[0023] In the following description, for the purpose of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc., in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to those skilled in the art that the present application can be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

[0024] In order to make the objectives, technical solutions and advantages of the present application clearer, the following will be described with reference to the accompanying drawings through specific embodiments.

[0025] Reference will be made to Figure 1 , Figure 1 A flowchart of an intelligent grouping method for submerged arc welding steel pipes is provided for an embodiment of the present application. The method can be executed by an electronic device, and for each submerged arc welding steel pipe produced by a target production line, the method can include S101-S103. The target production line is used to produce submerged arc welding steel pipes.

[0026] S101: Real-time acquisition of production information of the submerged arc welding steel pipe; the production information includes a current production project corresponding to the submerged arc welding steel pipe.

[0027] In the present embodiment, the submerged arc welding steel pipe is a steel pipe produced by using a submerged arc welding process. Submerged arc welding is a method of welding by burning an electric arc under a layer of flux, which has the characteristics of high welding efficiency and good weld quality, and is widely used in the fields of oil and natural gas pipelines. The production information is a quantitative or qualitative representation of the steel pipe production process and result. For example, the production information can include the current production project, production unit, grade, wall thickness, process and production time corresponding to the submerged arc welding steel pipe, and can also include the voltage, current and their respective fluctuation parameters of each processing equipment in the process of processing the submerged arc welding steel pipe in the target production line. The production project can be each process in the process of processing the steel plate into the submerged arc welding steel pipe, such as edge milling or edge planing treatment of the steel plate, edge rolling process, welding process, expanding process, hydraulic testing process, non-destructive testing process, heat treatment process, appearance and geometric dimension measurement process, weight measurement process or performance testing process, etc.

[0028] In the embodiment, production information can be obtained in real time based on various sensors arranged in the target production line, and relevant personnel can also enter the production information manually so that the electronic device obtains the production information.

[0029] S102: Determine the production batch corresponding to the submerged-arc welded steel pipe based on the production information of the submerged-arc welded steel pipe and a preset batching rule.

[0030] In the embodiment, the preset batching rule can be determined based on the requirements in Annex A of TSGD7006-2020 Supervision and Inspection Rules for Pressure Pipe, and specifically, the inspection rules require that the same unit, the same brand, the same outer diameter, the same wall thickness, the same process, the production cycle not exceeding 7 days, and the number not exceeding 200 are one batch; the product quality is stable, and no quality problems have been found for one year, and the number of batches can be increased, but each batch cannot exceed 600. In addition to the above requirements in the supervision and inspection rules for pressure pipes, relevant personnel can also add other limitations or adaptive adjustments to achieve batching suitable for actual production processes.

[0031] In the embodiment, the purpose of batching is to facilitate quality inspection and traceability. Steel pipes in the same batch usually have similar production conditions, such as production parameters, time, process, etc. After being grouped into a batch, the inspector can perform inspection tasks uniformly for the whole batch of steel pipes, such as batch sampling and recording quality data. If quality problems are found later, all steel pipes in the same batch can be quickly located, potential problems in the production process can be traced back, and the quality control efficiency can be improved. At the same time, the division of production batches can be more orderly, and the risk of delayed or missed inspection due to excessive data volume can be reduced.

[0032] In the embodiment, the production batch refers to a collection of a plurality of submerged-arc welded steel pipes grouped according to the preset batching rule. Each production batch can be named differently, such as A01, A02, or A, B, etc. The production information of the submerged-arc welded steel pipes in each production batch, such as production unit, brand, outer diameter, wall thickness, and process, is consistent. Therefore, in the embodiment, the batch to which the submerged-arc welded steel pipe belongs can be determined based on the production information of the submerged-arc welded steel pipe and the preset batching rule.

[0033] S103: Determine the target inspection task corresponding to the production batch based on the current production project, and send the target inspection task to the target device; the target inspection task is used to remind the target personnel to inspect the submerged-arc welded steel pipe corresponding to the production batch.

[0034] In the embodiment, the target monitoring task refers to a quality inspection task that needs to be completed for a specific production batch of steel pipes and is directly related to the current production project. For example, if the production project is a non-destructive testing process, the target monitoring task can be ultrasonic testing range confirmation and defect judgment standard implementation. Determining the target monitoring task corresponding to the production batch based on the current production project refers to determining the quality monitoring content that needs to be performed for the batch of steel pipes according to the specific production process to which the steel pipes belong, such as welding, hydraulic testing, etc. For example, if the current production project is a welding process, the corresponding target monitoring task can include welding inspection, such as welder qualification inspection, welding parameters, welding outer tube sampling inspection, and repair sampling inspection, etc. If the production project is a hydraulic testing process, the monitoring task can be pressure test inspection, etc. Different production projects correspond to different target monitoring tasks.

[0035] In the embodiment, after determining the target monitoring task, the target monitoring task can be sent to the target device to remind the target personnel to perform the corresponding monitoring. The target device is a terminal device corresponding to the target personnel, and the target device can be a terminal device such as a mobile phone, a tablet, or a computer of the target personnel. The target personnel is a worker responsible for performing the monitoring task.

[0036] From the above, it can be concluded that the embodiment of the present application can obtain the production information of each submerged arc welded steel pipe produced by the target production line in real time, including the corresponding current production project, determine the production batch based on these production information and the preset grouping rule, accurately divide the batch according to the actual production situation of the steel pipe according to the established rule, solve the grouping difficulty problem caused by complex data, make the grouping more scientific and reasonable. After determining the production batch, the embodiment of the present application determines the target monitoring task corresponding to the production batch based on the current production project, and sends the target monitoring task to the target device, which can timely and accurately convey the monitoring task to the relevant monitoring personnel, remind them to monitor the submerged arc welded steel pipe of a specific production batch, avoid monitoring omission, ensure the efficient and accurate execution of the monitoring work, and further ensure the safety and compliance of the submerged arc welded steel pipe product, and improve the product quality and controllability of the production process.

[0037] In an embodiment of the present application, the production information further includes: a production time and a production parameter group; the production parameter group contains at least one production parameter;

[0038] The preset grouping rule includes: taking the submerged arc welded steel pipes with the same production parameter group and a production time difference value not exceeding a preset time length as one production batch, and the number of submerged arc welded steel pipes in each production batch does not exceed a preset number; the production time difference value refers to the difference between the production times of any two submerged arc welded steel pipes in the same production batch;

[0039] Determine the production batch corresponding to the submerged-arc welded steel pipe based on the production information of the submerged-arc welded steel pipe and the preset batch grouping rule, including:

[0040] Determine the target historical production batch from a plurality of historical production batches based on the production time corresponding to the submerged-arc welded steel pipe; the historical production batch is a historically created production batch, and the number of submerged-arc welded steel pipes in each historical production batch is less than a preset number;

[0041] In response to being unable to determine the target historical production batch, create a production batch based on the production parameter group of the submerged-arc welded steel pipe, and divide the submerged-arc welded steel pipe into the created production batch; the production parameter group corresponding to the created production batch is the production parameter group of the submerged-arc welded steel pipe.

[0042] In this embodiment, the production parameter group refers to a set composed of at least one key parameter related to the production process, and as an optimization, at least the parameters in the preset batch grouping rule should be included, such as production unit, grade, outer diameter, wall thickness, process, etc. In this embodiment, the preset batch grouping rule can be set based on the aforementioned “Pressure Pipe Supervision and Inspection Rules” as follows: the submerged-arc welded steel pipes with consistent production parameter groups and a production time difference value not exceeding a preset time length are taken as one production batch, and the number of submerged-arc welded steel pipes in each production batch does not exceed a preset number; the production time difference value refers to the difference between the production times of any two submerged-arc welded steel pipes in the same production batch.

[0043] In this embodiment, the preset time length can be 7 days (it can also be converted into other time units such as hours, minutes, or seconds, etc.). The preset number can be less than or equal to 200, or less than or equal to 600, and the specific value can be set based on historical inspection results. If the historical inspection results meet the product quality stability, no quality problems have been found for 1 year in succession, the preset number can be set to or less than or equal to 600, otherwise, the preset number is set to less than or equal to 200.

[0044] In this embodiment, the historical production batch refers to the production batch to which the submerged-arc welded steel pipes historically produced by the target production line belong, that is, the historically created production batch, and the batch that has not reached the preset number. The target historical production batch refers to the unfulfilled batch that meets the production time condition selected from the historical production batch.

[0045] If no historical production batch meeting the time condition is found through screening, for example, all existing historical production batches are full, and / or the production time is more than a preset time length from the current steel pipe, a production batch can be created based on the production parameter group of the submerged-arc welded steel pipe, and the submerged-arc welded steel pipe is divided into the created production batch. That is, the current steel pipe is taken as the first submerged-arc welded steel pipe of the new batch. The production parameter group corresponding to this production batch is also the production parameter group of the submerged-arc welded steel pipe. When a submerged-arc welded steel pipe with the same parameter group is produced subsequently, the interval between the production time of the submerged-arc welded steel pipe and the production time of the current steel pipe is not more than the preset time length, and the number of submerged-arc welded steel pipes in the created production batch does not reach the preset number, the submerged-arc welded steel pipe can be classified into the created production batch.

[0046] From the above, it can be concluded that the embodiment of the present application incorporates the production time and the production parameter group into the production information and sets the submerged-arc welded steel pipes with the same production parameter group and the production time difference not more than the preset time length as a production batch, and the number of each batch does not exceed the preset number. The group batch rule comprehensively considers the key elements of the production process, can accurately classify the steel pipes with similar production characteristics and similar production time into the same batch, and avoids the grouping confusion caused by complex production conditions. At the same time, in actual production, the production rhythm and quantity of different specifications and models of steel pipes are different, and the above grouping strategy can adapt to various production scenes. Whether it is the first production of a new specification steel pipe or the re-production of an existing specification steel pipe, the batch can be reasonably divided to ensure that the steel pipes in each batch have high homogeneity and relevance. The embodiment classifies the submerged-arc welded steel pipes with similar characteristics and similar production time into the same batch through reasonable grouping, so that the inspectors can concentrate on monitoring each batch, reducing the workload and time cost of the inspectors. At the same time, since the steel pipes in the same batch have high consistency in production parameters and production time, the monitoring result can more accurately reflect the overall quality condition of the steel pipes in the batch. Once a quality problem is found, the specific batch can be quickly located, the cause of the problem can be analyzed, and targeted improvement measures can be taken to avoid the problem from being enlarged, and the accuracy and effectiveness of the monitoring are improved.

[0047] In an embodiment of the present application, determining the production batch corresponding to the submerged-arc welded steel pipe based on the production information of the submerged-arc welded steel pipe and the preset group batch rule further includes:

[0048] In response to determining that the target historical production batch is at least one, the production parameter group of the submerged-arc welded steel pipe is matched with the production parameter group corresponding to each target historical production batch to obtain a matching result corresponding to each target historical production batch. The production parameter groups corresponding to the target historical production batches are different.

[0049] In response to the target matching result existing in each matching result, the submerged-arc welded steel pipe is divided into a target historical production batch corresponding to the target matching result; the target matching result is a matching result that is consistent among the matching results;

[0050] In response to the target matching result not existing in each matching result, a production batch is created based on the production parameter group of the submerged-arc welded steel pipe, and the submerged-arc welded steel pipe is divided into the created production batch; the production parameter group corresponding to the created production batch is the production parameter group of the submerged-arc welded steel pipe.

[0051] In the embodiment, if the target historical production batch is at least one, that is, the target historical production batch can be determined, the production parameter group of the submerged-arc welded steel pipe can be matched with the production parameter group corresponding to each target historical production batch. It should be noted that in the matching process in the embodiment, each parameter in the parameter group should be matched one by one. For example, the production unit should be matched with the production unit, and the grade should be matched with the grade. Only when the plurality of production parameter groups of the submerged-arc welded steel pipe are completely consistent with the production parameter group corresponding to a target historical production batch, that is, the matching result is a target matching result, the submerged-arc welded steel pipe can be divided into the target historical production batch.

[0052] In the embodiment, if the target matching result does not exist in each matching result, it indicates that the production parameter groups of all target historical batches are inconsistent with the current steel pipe. At this time, a production batch should be created based on the production parameter group of the submerged-arc welded steel pipe, and the submerged-arc welded steel pipe is divided into the created production batch. The creation process is consistent with the foregoing, and will not be described herein again.

[0053] From the above, in the case that at least one target historical production batch can be determined, the plurality of production parameter groups of the current submerged-arc welded steel pipe are accurately matched one by one with the production parameter groups corresponding to each target historical production batch. Only when the plurality of production parameter groups of the submerged-arc welded steel pipe are completely consistent with the production parameter groups corresponding to a certain target historical production batch, the submerged-arc welded steel pipe is divided into the target historical production batch, so that the submerged-arc welded steel pipes in each batch are highly consistent in production parameters, thereby having stronger homogeneity in production process, quality characteristics and the like. The batch with high homogeneity can more accurately reflect the overall quality level of the steel pipes in the batch, so that the monitoring and inspection results are more representative and reliable. When there is no target matching result in each matching result, i.e., the production parameter groups of all target historical batches are inconsistent with the current steel pipe, the embodiment creates a new production batch, which ensures that the production process will not be interrupted due to the inability to batch when a steel pipe with a new parameter combination is encountered, thereby maintaining the continuity of production. In addition, the steel pipes in the new batch have the same production parameter group, which meets the requirements of the batch grouping rule, so that the new batch has rationality and operability in subsequent monitoring and management.

[0054] In an embodiment of the present application, the target historical production batch is determined from the plurality of historical production batches based on the production time corresponding to the submerged-arc welded steel pipe, including:

[0055] For each historical production batch:

[0056] The creation time corresponding to the historical production batch is obtained;

[0057] In response to the difference between the creation time corresponding to the historical production batch and the production time of the submerged-arc welded steel pipe being greater than a preset time length, the historical production batch is excluded;

[0058] In response to the difference between the creation time corresponding to the historical production batch and the production time of the submerged-arc welded steel pipe being less than or equal to a preset time length, the historical production batch is determined as the target historical production batch.

[0059] In the embodiment, the creation time can be taken as the screening criterion to select the batch with the production time difference from the current steel pipe production time within the preset range from the existing unfilled batches. Specifically, if the difference between the creation time of the historical production batch and the production time of the submerged arc welded steel pipe is greater than the preset time length, the historical production batch is excluded. In the embodiment, the reason for taking the creation time as the screening criterion is that a new production batch is created because no submerged arc welded steel pipe with the same production parameter set is produced within the preset time length or the submerged arc welded steel pipe with the same production parameter set is produced within the preset time length, but the number of the submerged arc welded steel pipes in the batch reaches the preset number. Therefore, when a production batch is created, the production time is necessarily the earliest, the production time of the subsequently produced submerged arc welded steel pipe is necessarily later than the production time, and the production time of the submerged arc welded steel pipe divided into the production batch is necessarily later than the creation time of the production batch.

[0060] Therefore, if the time difference exceeds the preset time length, the historical batch does not meet the preset group batch rule and is no longer a candidate batch. The batch with a too large production time difference is filtered out through the time threshold, the production time of the steel pipes in the same batch is ensured to be within a reasonable range, and the submerged arc welded steel pipes with a large time span are prevented from being divided into a group, thereby reducing the monitoring and inspection quality of the submerged arc welded steel pipes. Conversely, if the time difference is within the preset time length, the batch meets the time condition and becomes a candidate batch for subsequent parameter matching, that is, a target historical production batch.

[0061] As can be seen from the above, in the embodiment, the difference between the creation time of the historical production batch and the current production time of the submerged arc welded steel pipe is taken as the screening basis, the historical production batch with a difference greater than the preset time length is excluded, and only the historical production batch with a difference less than or equal to the preset time length is reserved as the target historical production batch. The batch with a similar production time to the current steel pipe production time can be accurately selected from the numerous historical production batches as a candidate, and the steel pipes with a large production time span are prevented from being divided into the same batch. In the embodiment, the batch with a too large production time difference is filtered out through the time threshold, the production time of the steel pipes in the same batch is ensured to be within a reasonable range, the monitoring and inspection personnel can concentrate on monitoring the steel pipes with relatively consistent production conditions, the quality condition of the steel pipes in the batch can be more accurately evaluated, the quality risk is reduced, and the overall quality level of the product is improved.

[0062] In an embodiment of the present application, the target monitoring task includes a target monitoring level, a target monitoring item, and a target standard file; the target standard file is a standard file corresponding to the target monitoring item;

[0063] The target monitoring task is determined based on the current production item, including:

[0064] The current production item is determined as the target monitoring item;

[0065] determine a target inspection level based on the current production item and a first mapping table; the first mapping table is used to represent a mapping relationship between each production item and each inspection level;

[0066] determine a target standard file based on the current production item and a second mapping table; the second mapping table is used to represent a mapping relationship between each production item and each standard file.

[0067] In the embodiment, the target inspection task is a general term of quality supervision and inspection tasks that need to be performed for a specific production batch, and is also a specific basis for guiding the work of the inspector, which includes the target inspection level, the target inspection item and the target standard file. The target inspection level refers to the strictness or depth of inspection, such as routine inspection, intensified inspection, sampling ratio, etc. The higher the level, the more stringent the inspection. It can also be divided according to alphabetical levels such as A, B and C levels. A level is more important than B and C levels. For example, A level refers to key items that have a significant impact on the safety performance of pressure pipes. When the manufacturing process reaches the point of such items, the inspector should be notified in advance to arrive on site, and the inspector supervises the implementation of the item on site. Its result is confirmed to be qualified by the inspector on site and signed, and then the manufacturing can continue. B level is a key item that has a greater impact on the safety performance of pressure pipes. The inspector generally supervises on site or inspects the physical object. If the inspector cannot arrive on site in time, the inspected unit can continue to manufacture the item after self-inspection. The inspector subsequently inspects the manufacturing result on site to confirm whether the item meets the requirements. C level is an inspection item that has an impact on the safety performance of pressure pipes. The inspector confirms whether the item meets the requirements by reviewing the relevant self-inspection report records and other data of the inspected unit.

[0068] In the embodiment, the target inspection item refers to the specific content that needs to be inspected, such as the result of hydraulic test or non-destructive testing result, etc. The target standard file refers to a technical file used to regulate the inspection item, which can be a national standard, an industry specification, an enterprise internal standard, etc. It specifies what standards and indicators the current production batch should meet. Different production items, i.e. different production processes, correspond to different standard files.

[0069] In the embodiment, the target inspection level can be determined based on the current production item and the first mapping table, for example, it can be determined based on Table 1. It should be noted that Table 1 is only an exemplary part of the table and does not exhaust all mapping relationships.

[0070]

[0071] Similarly, in the embodiment, the target standard file can also be determined based on the current production item and the second mapping table. The second mapping table is not described again in the embodiment.

[0072] From the above, the embodiment can make each production batch obtain the inspection task highly consistent with its own production characteristics by explicitly determining the current production project as the target inspection project and accurately determining the target inspection level and the target standard file according to the first mapping table and the second mapping table, different production projects have different quality risk points and key inspection indexes, the inspection personnel can focus on the core quality problems of the production batch, avoid the single inspection mode, improve the pertinence and effectiveness of the inspection work, and ensure that the quality of each production batch can be effectively controlled.

[0073] In an embodiment of the present application, if the step of creating a production batch based on the production parameter group of the submerged-arc welded steel pipe is performed in the process of determining the production batch corresponding to the submerged-arc welded steel pipe based on the production information of the submerged-arc welded steel pipe and the preset batch grouping rule, the target inspection task corresponding to the production batch is determined based on the current production project, and the method further comprises:

[0074] re-determining the target inspection level to the highest inspection level; the highest inspection level is higher than any inspection level in the first mapping table.

[0075] In the embodiment, if the step of creating a production batch based on the production parameter group of the submerged-arc welded steel pipe is performed in the process of determining the production batch corresponding to the submerged-arc welded steel pipe based on the production information of the submerged-arc welded steel pipe and the preset batch grouping rule, it indicates that the submerged-arc welded steel pipe is the first submerged-arc welded steel pipe of a new batch, and the first one of a production batch should be checked most carefully. Therefore, the target inspection level should be re-determined to the highest inspection level regardless of the target inspection level determined in the foregoing step. It should be noted that the highest inspection level is not embodied in the first mapping table, and the highest inspection level is higher than any inspection level in the first mapping table.

[0076] In an embodiment of the present application, if the step of dividing the submerged-arc welded steel pipe into the target historical production batch corresponding to the target matching result is performed in the process of determining the production batch corresponding to the submerged-arc welded steel pipe based on the production information of the submerged-arc welded steel pipe and the preset batch grouping rule, and the number of submerged-arc welded steel pipes in the target historical production batch reaches the preset number after the submerged-arc welded steel pipe is divided into the target historical production batch corresponding to the target matching result, the target inspection task corresponding to the production batch is determined based on the current production project, and the method further comprises:

[0077] re-determining the target inspection level to the highest inspection level; the highest inspection level is higher than any inspection level in the first mapping table.

[0078] In the embodiment, if the step of dividing the submerged-arc welded pipe into the target historical production batch corresponding to the target matching result is performed in the process of determining the production batch corresponding to the submerged-arc welded pipe based on the production information of the submerged-arc welded pipe and the preset batch grouping rule, and the number of the submerged-arc welded pipes in the target historical production batch reaches the preset number after the submerged-arc welded pipe is divided into the target historical production batch corresponding to the target matching result, it is indicated that the submerged-arc welded pipe is the last submerged-arc welded pipe in the target historical production batch to which the submerged-arc welded pipe is added, the first pipe of a production batch should be most carefully checked, and therefore the target inspection level is re-determined to the highest inspection level regardless of the target inspection level determined in the foregoing step. It can be understood that if a submerged-arc welded pipe is the first pipe or the last pipe in a batch, an inspector should be reminded to perform inspection.

[0079] It can be concluded from the above that, in the embodiment, the target inspection level of the first submerged-arc welded pipe of a newly created production batch is re-determined to the highest inspection level, which can ensure that the starting pipe of the batch is most comprehensively and carefully checked. When the submerged-arc welded pipe is divided into a target historical production batch and the number of the batch reaches the preset number, the submerged-arc welded pipe becomes the last pipe of the batch, and the target inspection level of the submerged-arc welded pipe is also promoted to the highest. When the production of a batch is close to the end, the quality condition of the last pipe can reflect the situation of the later stage of the batch production to a certain extent. Strict inspection of the first pipe and the last pipe can help to find quality problems in the later stage of production and prevent unqualified products from flowing into the market, thereby further ensuring product quality.

[0080] In an embodiment of the present application, the intelligent batch grouping method for submerged-arc welded pipes further includes:

[0081] In response to the production information of the submerged-arc welded pipe satisfying a preset fluctuation condition, the target inspection level is re-determined to the highest inspection level; the highest inspection level is higher than any inspection level in the first mapping table; wherein the preset fluctuation condition is that an electrical fluctuation value is greater than a preset fluctuation threshold; the electrical fluctuation value is determined based on the production information of the submerged-arc welded pipe.

[0082] In the embodiment, the production information further includes an actual welding current, an actual welding voltage and an actual welding speed; whether the production information of the submerged-arc welded pipe satisfies the preset fluctuation condition can be determined based on the following manner:

[0083] obtaining a standard welding current, a standard welding voltage and a standard welding speed;

[0084] determining a current fluctuation based on the actual welding current and the standard welding current of the submerged-arc welded pipe;

[0085] determine the voltage fluctuation based on the actual welding voltage of the submerged-arc welded steel pipe and the standard welding voltage;

[0086] determine the speed fluctuation based on the actual welding speed of the submerged-arc welded steel pipe and the standard welding speed;

[0087] The current fluctuation, the voltage fluctuation and the speed fluctuation are weighted to determine the electrical fluctuation value.

[0088] In the embodiment, the standard welding current, the standard welding voltage and the standard welding speed can be determined based on the enterprise process card. The calculation formula of the current fluctuation can be | actual welding current - standard welding current | / standard welding current * 100%. The calculation method of the voltage fluctuation and the speed fluctuation is the same. If the electrical fluctuation value obtained by weighting the current fluctuation, the voltage fluctuation and the speed fluctuation is relatively large, it indicates that the current production parameters of the submerged-arc welded steel pipe are unstable, and abnormalities may occur, so the monitoring and inspection personnel can be reminded to conduct on-site monitoring and inspection.

[0089] In the embodiment, in addition to the actual welding current, the actual welding voltage and the actual welding speed in the welding process, the actual detection result and the standard detection result in the nondestructive testing process can also be compared. For example, if an out-of-standard defect is found, the target monitoring and inspection level can be re-determined to the highest monitoring and inspection level. The monitoring and inspection personnel can set other conditions for triggering the re-determination of the target monitoring and inspection level to the highest monitoring and inspection level according to actual needs.

[0090] From the above, the embodiment of the present application sets the preset fluctuation condition, re-determines the target monitoring and inspection level to the highest monitoring and inspection level when the production information of the submerged-arc welded steel pipe meets the condition, can respond in a timely manner according to the actual situation in the production process, and ensures that the steel pipe is more strictly and meticulously monitored when the production parameters abnormally fluctuate, thereby improving the accuracy of product quality control.
