pressure pipe

I would like to ask everyone, now we are testing the wall thickness of pressure pipelines. How to determine whether the pressure pipelines are safe to use? Is there a standard? When should the line:handshake be replaced?
There is stress calculation software. You can calculate it based on the software.

Questions for landlords: First: To check the stress level of the pressure pipeline from the perspective of stress calculation to determine the safety level of the pipeline, it is recommended to use CAESAR_II software performs simulation calculations. second: The safety level of the pipeline is determined through the design of the determined parameters related to pipeline corrosion. third: The quality level of pipeline design and installation is determined through GB 50184-1993 Industrial Metal Pipe Engineering Quality Inspection and Assessment Standards. GB 50235-97 Industrial Metal Pipe Engineering Construction and Acceptance Specifications and other relevant specifications. To determine the safety of the pressure pipeline. Through the above 3 points, I think the poster should know what to do!

I totally agree with the theoretical basis above. But it is recommended to have a clear value as a reference. In addition, it costs money to hire someone to inspect the pipeline.
There are clear instructions in the design documents.
1. The pipe thinning value is not greater than the design allowance. 2. There are no obvious defects in key parts such as elbows. It is best to contact the local safety supervision department for inspection. It is good for both the public and oneself.
During actual operation, the actual wall thickness of the pipe should be measured. If it is within the range of the design requirements, it will be fine. If the pipe wall (especially elbows and other places where stress is concentrated) is not thick enough, the pipe fittings should be replaced as soon as possible.
