Description

Technical Field

[0001] The present invention relates to a steel pipe information query system, and in particular to a steel pipe butt welding method and an off-line steel pipe information query system, belonging to the technical field of oil and gas transmission pipeline production and construction. Background Art

[0002] The conveying medium of high-pressure oil and gas transmission pipelines is flammable and explosive, making "how to further improve the safety and reliability of pipelines" the most important issue throughout the entire pipeline construction industrial chain. Multiple high-pressure oil and gas transmission pipeline failure accidents that have occurred in recent years indicate that quality defects in the girth welds of steel pipes are the main cause. To reduce the quality risk of on-site girth welds, pipeline construction has put forward higher requirements for the perimeter and out-of-roundness quality of pipeline components such as steel pipes and hot-bent elbows, requiring a narrower strength change range to control the stress of on-site girth weld butt joints, achieve excellent matching of girth weld joints, and provide necessary conditions for the use of fully automatic welding for on-site girth welds.

[0003] In the construction of oil and gas transmission pipelines, steel pipe butt welding is the key to affecting construction quality and progress. The traditional manual observation butt welding method severely restricts the improvement of the butt welding quality level. The mechanical rough forming makes it extremely difficult to further improve the dimensional accuracy of the ends of large-diameter submerged arc steel pipes. Providing macroscopic dimension data of each steel pipe in real time at the construction site and achieving the optimal matching butt joint of the steel pipe ends are the keys to enhancing the inherent safety of oil and gas transmission pipelines.

[0004] Starting from the requirements of oil and gas pipeline construction, realizing digital support for the entire life cycle of steel pipes from raw materials, product manufacturing, product storage and transportation, construction, operation and maintenance, etc. can significantly improve the level of inherent safety assurance of oil and gas transmission pipelines. Since a large number of steel pipes are used in the same project and each steel pipe needs to be tracked one by one, the information of each steel pipe is large and there are non-negligible differences. The information comes from different manufacturing links, and the information collection and application involve different internal and external entities or departments. During the transportation and use of steel pipes, they need to face various natural environments such as high temperature, cold, rain, snow, swamps, mountains, deserts, etc., and there is a lack of information network support in the wild, which restricts the comprehensive and timely acquisition of steel pipe information. At present, during the processes of steel pipe delivery, transportation, delivery, transfer stacking, on-site pipe laying, and butt welding, steel pipe information is obtained through shipping documents, markings on the inner and outer surfaces of steel pipes, etc., and only some basic information of the steel pipe can be known, such as pipe number, specification, length, diameter, etc. It cannot meet the needs of current high-quality oil and gas pipeline construction in terms of timeliness and comprehensiveness. Especially during transportation, transfer stacking, on-site pipe laying, and butt welding, there are no off-line query conditions for steel pipe information, and all the characteristics and detailed information of the end of each steel pipe cannot be obtained during on-site butt welding, making it difficult to achieve the best matching of butt-welded steel pipes, and seriously affecting the further improvement of on-site steel pipe girth weld quality and construction efficiency. Summary of the Invention

[0005] In order to overcome the above-mentioned deficiencies in querying comprehensive information of steel pipes and optimal pipe pairing information in the construction of existing high-quality oil and gas pipelines, the present invention provides a steel pipe pairing method and an offline query system for steel pipe information.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a steel pipe pairing method, including an offline query system for steel pipe information, and its steps are as follows:

[0022] S2-4. According to the pairing rules, automatically search in the data of the relevant information of the steel pipes required for construction for the information data of the pipe end circumference and the pipe end out-of-roundness that match the B end of the steel pipe with serial number 001, confirm and identify the serial number 002 of this steel pipe and its A end.

[0023] S2-5. According to the information data of the pipe end circumference and the pipe end out-of-roundness of the B end of the steel pipe with serial number 002, automatically search in the relevant information data of the steel pipes for the information data of the pipe end circumference and the pipe end out-of-roundness that have not been paired and match the B end of the steel pipe with serial number 002, confirm and identify the serial number 003 of this steel pipe and its A end.

[0024] S2-6. Loop step S2-5, sequentially number 004, 005... and the A end and B end of each steel pipe according to the steel pipe pairing order until the automatic pairing of all steel pipes is completed.

[0042] See the attached Figure 1 、 2 . A steel pipe pairing method of the present invention includes a steel pipe information offline query system, and its steps are as follows:

[0043] S1. The mobile terminal 1 logs in to the application server 2 to obtain relevant information data of the steel pipe information database 4 and cache it. Specifically as follows:

[0044] S1-1. Judge the network environment of the mobile terminal 1

[0045] If it is already connected to the network, log in to the app;

[0046] If there is no network, set up a network connection, enter the networked state and log in to the app;

[0048] S1-3. Obtain the steel pipe numbers required for construction related to the contract and their relevant information;

[0049] S1-4. Cache the steel pipe numbers required for construction and their relevant information in the mobile terminal 1.

[0050] S2. Apply the steel pipe information data of the mobile terminal 1 at the construction site to optimize the completion of steel pipe pairing, specifically as follows:

[0051] S2-1. Judge the network environment of the mobile terminal 1,

[0052] If online, access the application server 2 through the mobile terminal 1 or the computer 6 to obtain real-time steel pipe information data;

[0053] If offline, access the steel pipe information data cached in the mobile terminal 1;

[0054] S2-2. Query the steel pipe numbers required for construction and their relevant information data;

[0055] S2-3. Determine the steel pipe No. 001, and obtain the information data of the pipe end circumference and pipe end out-of-roundness of the B end morphology of the No. 001 steel pipe;

[0056] S2-4. According to the pairing rules, automatically search in the relevant information data of the steel pipes required for construction for the information data of the pipe end circumference and pipe end out-of-roundness that match the B end of the No. 001 steel pipe, confirm and mark the steel pipe No. 002 and its A end;

[0057] S2-5. According to the information data of the pipe end circumference and pipe end out-of-roundness of the B end of the No. 002 steel pipe, automatically search in the relevant information data of the steel pipes for the information data of the pipe end circumference and pipe end out-of-roundness that have not been paired and match the B end of the No. 002 steel pipe, confirm and mark the steel pipe No. 003 and its A end;

[0058] S2-6. Loop step S2-5, and sequentially number 004, 005... and the A end and B end of each steel pipe according to the steel pipe pairing order until the automatic pairing of all steel pipes is completed;

[0059] S2-7. Store or cache the pairing information;

[0060] S2-8. Store or cache the completion information.

[0061] Further, the pairing rules in the step S2-4 include: the difference in the pipe end circumference and pipe end out-of-roundness dimensions of the steel pipes, and the priority order of the pipe end circumference and pipe end out-of-roundness of the steel pipes.

[0062] Further, in the pipe pairing rules, priority is given in the order of the pipe end circumference and the pipe end out-of-roundness of the steel pipe.

[0063] Furthermore, in the steel pipe application software 5, there is a preset range of dimensional differences in the pipe end circumference and the pipe end out-of-roundness of the paired steel pipes, which can be selected as needed. The range of dimensional differences in the pipe end circumference and the pipe end out-of-roundness for steel pipe pairing is related to the steel pipe diameter, that is, it can be preset in advance or manually set according to the on-site steel pipe pairing requirements.

[0064] Each contract is associated with a customer. When the customer logs in to the mobile terminal app, the system will obtain the associated contracts of the user based on the user ID, and obtain the information data related to the steel pipe numbers that the customer can view according to the contract information.

[0065] See Appendix Figure 3 A steel pipe information offline query system of the present invention includes a mobile terminal 1, an application server 2, an Internet access control server 3, a steel pipe information database 4, a steel pipe application software 5, and a computer 6. The app of the steel pipe application software 5 is installed on the mobile terminal 1, the application server 2, the Internet access control server 3, and the computer 6. The steel pipe numbers and steel pipe information are stored in the steel pipe information database 4.

[0066] The cache interface uses the RESTful API of a Web service architecture that communicates using the HTTP protocol, and operates and accesses the application server 2 and the steel pipe information database 4 through standard HTTP methods and the URI (Uniform Resource Identifier).

[0067] The user's mobile terminal 1 logs in to the application server 2 in an online state to obtain real-time steel pipe data, and the steel pipe data is cached in the mobile terminal app; the user logs in to the mobile terminal app in an offline state and enables the cache interface to obtain the steel pipe data cached in the mobile terminal app.

[0068] When each steel pipe is taken offline from the production line and put into storage, a two-dimensional code label containing the pipe number and information data is attached.

[0069] The steel pipe information database 4 extracts steel pipe information in units of roots according to the pipe numbers. The steel pipe information includes: manufacturer, specification, steel pipe dimensions, pipe end morphology, physical and chemical properties, and execution standards.

[0070] Further, the pipe end morphology includes: pipe end circumference and pipe end out-of-roundness.

[0071] The steel pipe information data includes but is not limited to: manufacturer, specification, raw materials, chemical composition, metallography, mechanical properties, non-destructive inspection results, macroscopic dimensions (length, pipe end circumference, pipe end out-of-roundness, overall pipe end morphology, misalignment, pouting), execution standards, etc.

[0072] The construction operations of oil and gas pipelines are mostly carried out in relatively remote areas. Before entering the construction area without network signal, first log in to the mobile terminal system, obtain the data of welded steel pipes required for construction operations, and cache them in the memory of the mobile terminal.

[0073] Applying the steel pipe alignment method and the offline query system for steel pipe information of the present invention, after the steel pipes required for the project arrive at the construction site, on-site alignment is carried out before welding, and adjustments can also be made during construction.

[0074] First, by logging in to the mobile terminal system, scanning the code or entering the pipe number, obtain the basic information of the steel pipe and geometric information such as the pipe end circumference and pipe end out-of-roundness of the steel pipe on the mobile terminal, and select the pipe end to be welded.

[0075] For the ports of the steel pipes that need to be welded, the system intelligently judges whether it meets the size difference range of the welding port by comparing the difference information of the selected pipe end circumferences and pipe end out-of-roundness of the two steel pipes. If not, the system prompts that it does not meet the pipe end matching requirements.

[0076] Then, adjust the welding port according to the prompt information, or replace the steel pipe until the pairing condition is met.

[0077] When the ports of the two steel pipes meet the pairing conditions, the system prompts that the pairing is successful, click to confirm, and record the paired steel pipe information.

[0078] Embodiment

[0079] For the steel pipe alignment of the contract for the X construction section of the M oil and gas pipeline, the steps are as follows:

[0080] S1. The mobile terminal logs in to the application server, obtains and caches the relevant information data of the steel pipe information database involved in the contract for the X construction section of the oil and gas pipeline.

[0081] S1-1. Judge the network environment of the mobile terminal. If it is connected to the network, log in to the app.

[0084] S1-4. Cache the pipe numbers of the steel pipes required for construction and their relevant information in the mobile terminal.

[0087] S2-2. Query the steel pipe numbers required for construction and their related information data;

[0088] S2-3. Determine the steel pipe No. 001, and obtain the information data of the pipe end circumference and pipe end out-of-roundness of the B-end morphology of the No. 001 steel pipe;

[0089] S2-4. Automatically search in the relevant information data for the information data of the pipe end circumference and pipe end out-of-roundness of the steel pipe that matches the B-end of the No. 001 steel pipe. When the information data of a certain steel pipe meets the pairing requirements, confirm and mark the serial number 002 and the A-end of the steel pipe;

[0090] S2-5. According to the information data of the pipe end circumference and pipe end out-of-roundness of the B-end of the No. 002 steel pipe, automatically search in the relevant information data for the information data of the pipe end circumference and pipe end out-of-roundness of the steel pipe that has not been paired and meets the pairing requirements with the B-end of the No. 002 steel pipe. When the information data of a certain steel pipe meets the pairing requirements, confirm and mark the serial number 003 and the A-end of the steel pipe;

[0091] S2-6. Loop through step S2-5, and sequentially number 004, 005... and the A-end and B-end of each steel pipe according to the steel pipe pairing order until the automatic pairing of all steel pipes is completed;

[0092] S2-7. Cache the pairing information of the contract steel pipes in the X construction section of the M oil and gas pipeline;

[0093] S2-8. Cache the completion information;

[0094] When the mobile terminal can receive a network signal, the system background automatically submits the cached operation data to the remote server.

[0095] In the above S2-4, S2-5, and S2-6, if there are multiple steel pipes that meet the pairing conditions, you can confirm according to the system recommendation, or manually select one of them and confirm.

[0096] During the process of steel pipe pairing from start to end, the difference values of the steel pipe end circumference and end out-of-roundness dimensions should be set to increase from small to large according to needs.

[0097] When performing construction operations on-site, if the mobile device can receive a network signal, the on-site QR code scanning operation interacts with the Internet access control server; if the mobile terminal cannot receive a network signal, the mobile terminal QR code scanning operation will retrieve the locally cached data, perform intelligent judgment, and cache the operation data in the mobile terminal. When a network signal can be received, the system background automatically submits the cached operation data to the remote server.

[0098] When applying the present invention at the pipeline construction site, the user scans the QR code on the steel pipe through the mobile terminal 1 or manually enters the pipe number, and accesses the steel pipe information database 4 under the control of the Internet access control server 3 to query the comprehensive quality information of the steel pipe to be welded, especially the end morphology characteristics, so as to realize the optimal matching of steel pipe assembly and improve the efficiency and quality of girth welding construction, and promote the improvement of the essential safety level of the conveying pipeline.
