[0003] The piping system generally consists of three main parts: pipes, connectors, and devices. Different pipes are used to transport different materials. These pipes can be made of various materials, such as PVC, steel, copper, polyethylene, etc. Various connectors are used to connect pipes to each other and connect them to various devices connected to the piping system. These connections can include nuts, valves, couplings, etc. Various devices such as water pumps, transfer cases, air conditioning systems, heating and air conditioning devices are also connected to the piping system.

[0004] Most of the pipes in common pipeline systems are seamless steel pipes, and their processing procedures mainly include forging of pipe blanks, heating and perforation, rolling, shrinking and expanding, straightening, performance strength testing, packaging, etc. Among them, the performance strength test refers to the measurement of various parameters such as the outer dimensions, surface quality, bending performance, pressure resistance and sealing of the pipe. Performance testing is an important part of the pipeline production process.

[0005] According to different testing methods, pipeline performance strength tests can be divided into destructive tests and non-destructive tests. For example, tests on external dimensions, surface quality, and sealing performance are non-destructive tests, while tests on bending performance and pressure resistance performance are destructive tests. During the performance test, the test sequence should be arranged reasonably to reduce pipeline losses.

[0006] The above pipeline performance test process needs to be carried out on specific equipment. However, due to functional defects, the existing test equipment generally has the following problems when used for pipeline performance testing:

[0007] 1. The appearance inspection coverage is not comprehensive.

[0008] 2. It is impossible to select and adjust the test parts during bending and pressure resistance tests.

[0009] 3. It is inconvenient to transport and transfer pipelines between multiple different testing stations, the continuity of diversified testing is poor, and the testing efficiency is low.

[0010] 4. Improper testing sequence leads to detection errors.

[0011] 5. The air tightness test is inconvenient to operate.

[0012] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention
