To ensure that the performance parameters of the high-pressure manifolds used meet the requirements, regular testing must be conducted in accordance with standard regulations.

[0003] Since the wall thickness of high-pressure manifolds is constantly thinned due to erosion, which is a major cause of high-pressure manifold failure, the wall thickness of high-pressure manifolds needs to be tested during regular inspections.

[0004] However, due to the presence of high-pressure media within the high-pressure manifold, it is impossible to detect the pipe wall thickness under actual operating conditions. Summary of the Invention

A strain-pressure curve database was established to obtain the slope threshold of the strain-pressure curve corresponding to the high-pressure manifold that has not failed.

[0010] Multiple pressure values ​​are obtained inside the high-pressure manifold to be tested. Multiple strain values ​​are obtained on the outer wall of the high-pressure manifold to be tested corresponding to multiple pressure values. A strain-pressure curve is established under the current degree of loss of the high-pressure manifold to be tested, and the slope is calculated based on the strain-pressure curve.

[0011] The degree of wear of the high-pressure manifold under test is determined by comparing the slope of the strain-pressure curve under the current degree of wear with the slope threshold in the strain-pressure curve database.

[0012] In some embodiments, multiple pressure values ​​within the high-pressure manifold are obtained, and multiple strain values ​​corresponding to the multiple pressure values ​​are obtained on the outer wall of the high-pressure manifold, including:

[0013] Different pressures were applied to the pipes of the same high-pressure manifold to obtain different pressure values, and multiple strain values ​​were measured at the same location on the outer wall of the same high-pressure manifold.

[0014] In some embodiments, the method for establishing the ε-F curve under the current loss level of the high-pressure manifold is as follows: the method for establishing the strain-pressure curve under the current loss level of the high-pressure manifold is as follows: based on multiple pressure values ​​F and multiple strain values ​​ε corresponding to multiple pressure values ​​F, combined with the formula: ε=aF+b, the least squares method is used to linearly fit the strain-pressure curve, and the slope a is calculated.

[0015] In some embodiments, the greater the slope, the greater the current loss of the high-pressure manifold.

[0016] In some embodiments, measurements are taken at different levels of loss in the high-pressure manifold, including:

[0017] Multiple measurements were performed on the high-pressure manifolds that had not failed under different levels of loss.

[0018] Multiple measurements were performed on the failed high-pressure manifold under different levels of loss.

[0019] In some embodiments, the slope threshold is the slope value of the strain-pressure curve corresponding to the unfailed high-pressure manifold and the failed high-pressure manifold.

[0020] In some embodiments, the slope of the strain-pressure curve under the current loss level of the high-pressure manifold under test is used as a reference. , compared with the slope threshold in the strain-pressure curve database The comparison is used to determine the degree of loss in the high-pressure manifold under test, including:

[0021] like Greater than If the high-voltage manifold under test is in a failed state, then the high-voltage manifold under test is in a failed state. Less than If the high-pressure manifold under test is in normal working condition, then the test manifold is in normal working condition.

[0022] Secondly, the present invention also provides a high-pressure manifold wall thickness detection system, including a data acquisition unit, a data coordinator, and a host computer data processor;

[0029] Fourthly, the present invention also provides a computer-readable storage medium storing one or more programs that can be executed by one or more processors to implement the steps in the high-pressure manifold wall thickness detection method as described above.

[0030] Compared with existing technologies, this method obtains multiple strain-pressure curves by measuring high-pressure manifolds under different levels of loss. The method for establishing each strain-pressure curve involves acquiring multiple pressure values ​​within the high-pressure manifold pipeline, acquiring multiple strain values ​​on the outer wall of the high-pressure manifold corresponding to these pressure values, establishing a strain-pressure curve for the current level of loss of the high-pressure manifold, calculating the slope based on the strain-pressure curve, establishing a strain-pressure curve database based on multiple sets of strain-pressure curves, obtaining the slope threshold of the strain-pressure curve corresponding to unfailed high-pressure manifolds, and then acquiring the slope threshold of the strain-pressure curve within the pipeline of the high-pressure manifold under test. By obtaining multiple pressure values, the strain values ​​of the outer wall of the high-pressure manifold under test corresponding to these pressure values ​​are acquired. A strain-pressure curve is established under the current degree of wear of the high-pressure manifold under test. The slope of the strain-pressure curve under the current degree of wear of the high-pressure manifold under test is calculated. The slope of the strain-pressure curve under the current degree of wear of the high-pressure manifold under test is compared with the slope threshold in the strain-pressure curve database to determine the degree of wear of the high-pressure manifold under test. The above method uses the relationship between the internal pressure of the pipeline and the strain force of the outer wall of the pipeline to reflect the pipe wall thickness, thereby enabling rapid and effective detection of the actual working condition of the high-pressure manifold under test.

[0042] During implementation, multiple strain-pressure curves were obtained by measuring the high-pressure manifold under different levels of loss. The method for establishing each strain-pressure curve involved acquiring multiple pressure values ​​within the high-pressure manifold pipeline, acquiring multiple strain values ​​on the outer wall of the high-pressure manifold corresponding to these pressure values, establishing a strain-pressure curve for the current level of loss of the high-pressure manifold, calculating the slope based on the strain-pressure curve, and establishing a strain-pressure curve database based on multiple sets of strain-pressure curves. The slope threshold of the strain-pressure curve corresponding to the unfailed high-pressure manifold was then obtained. This process was further refined by acquiring multiple strain-pressure values ​​within the pipeline of the high-pressure manifold under test. This method involves obtaining multiple strain values ​​corresponding to multiple pressure values ​​on the outer wall of the high-pressure manifold under test, establishing a strain-pressure curve for the current wear level of the high-pressure manifold, and calculating the slope based on the strain-pressure curve.

[0045] In step S100, the method for establishing the strain-pressure curve under the current loss level of the high-pressure manifold is as follows:

[0046] S120. Based on multiple pressure values ​​F and multiple strain values ​​ε corresponding to multiple pressure values ​​F, and combined with the formula: ε=aF+b, the least squares method is used to linearly fit the strain-pressure curve, and the slope a is calculated.

[0047] Step S100 has explained how to establish the ε-F curve under the current loss level of the high-pressure manifold, wherein the larger the slope a is, the greater the current loss level of the high-pressure manifold.

[0048] Step S100 allows for measurements to be taken of the high-pressure manifold under different loss levels, thereby obtaining multiple sets of data. Curve (i.e., strain-pressure curve), where is The strain values ​​to be recorded in the strain-pressure curve database. The pressure values ​​to be recorded in the strain-pressure curve database are established.

Obtain multiple pressure values ​​corresponding to the outer wall of the high-pressure manifold under test. Multiple strain values Establish the current loss level of the high-voltage manifold under test. Curve, and according to The slope is calculated from the curve. .

[0054] It should be noted that, in establishing the above During the process, high-pressure manifolds have varying wall thicknesses. According to standards, measurements can be taken after 100 hours, 200 hours, ... 500 hours of operation, and more data will be stored. In the middle. Among them, the high-pressure manifold data after 500 hours of operation can be considered as the data of the failed high-pressure manifold.

[0055] After measuring the high-voltage manifold under test and establishing its current loss level... After the curve is obtained, the current loss level of the high-pressure manifold under test can be directly obtained. slope of the curve Then, the operating condition of the high-pressure manifold under test can be determined according to step S400. Specifically, according to... and To determine the degree of loss in the high-pressure manifold under test.

[0056] In step S400, according to and To determine the degree of loss in the high-voltage manifold under test, the following measures are taken:

[0057] like Greater than If the high-voltage manifold under test is in a failed state, then the high-voltage manifold under test is in a failed state. Less than If the high-pressure manifold under test is in normal working condition, then the test manifold is in normal working condition.

[0058] In summary, by measuring the high-pressure manifold under different loss levels, multiple sets of data were obtained. Curve, each The method for establishing the curve is as follows: obtain multiple pressure values ​​F inside the high-pressure manifold, obtain multiple strain values ​​ε on the outer wall of the high-pressure manifold corresponding to the multiple pressure values ​​F, establish the ε-F curve under the current loss level of the high-pressure manifold, and calculate the slope a based on the ε-F curve.
