Description

technical field [0001] The invention relates to the technical field of strength detection of three-way pipe fittings, in particular to a manufacturing strength detection device of a three-way pipe fitting. Background technique [0002] Three-way pipe fittings are important and large-scale fittings in oil and gas pipeline engineering. It is used in pipeline construction to change the direction of the pipeline, change the diameter of the pipe, branch the pipeline and realize special connections. In recent years, the construction of oil and gas pipelines has entered the peak period of development, and the three-way pipe fittings also tend to develop in the direction of high strength, large diameter, thick wall and high performance. The production process of the tee is complex, and there are many factors affecting the quality and performance. Due to the geometric structure of the tee fitting and the complexity of the external load, it often leads to a dangerous part with high s...

Problems solved by technology

The production process of the tee is complicated, and there are many factors affecting the quality and performance. Due to the geometric structure of the tee fitting and the complexity of the external load, it often becomes a dangerous part of the pipe system with high stress concentration.

[0003] In the process of liquid transportation, the water hammer effect often occurs inside the pipeline, which causes the inner wall of the pipeline to be impacted. Therefore, it is necessary to vibrate it when testing the strength of the tee fittings, and detect the vibration at the joint by simulating the vibration generated by the water hammer effect. Whether the strength is qualified, but the current existing pipe fitting strength detection device can only detect the single vibration amplitude of the pipe when testing the pipe, which is inconvenient to test the withstand strength of the three-way pipe fittings when they are subjected to different impact forces, which affects the test results. The accuracy reduces the scope of application; in addition, because the shape of the three-way pipe can be divided into positive three-way and oblique three-way, the existing detection equipment can only detect single-shaped three-way pipe fittings, and the scope of use is limited.
