[0002] Pipe fittings are a general term for parts in pipeline systems that play roles in connection, control, direction change, diversion, sealing, and support. Pipe fittings, such as straight-through joints, need to be tested for thickness after processing. In the metallurgical industry, professional automated ultrasonic testing systems are mainly used to test the wall thickness of steel pipes.

[0003] The patent with application number 201721016849.3 discloses an ultrasonic detection device for layered detection and thickness measurement of thin-walled steel pipes, including: a base, a positioning block is installed at the bottom of the base, the positioning block has an opening that matches the outer diameter of the steel pipe to be tested, and the base is arranged on the outer diameter of the steel pipe to be tested in a manner perpendicular to the axis of the steel pipe to be tested through the positioning block; a mounting hole is penetrated from the bottom of the top of the base, an ultrasonic detection probe is arranged in the mounting hole, a delay block is arranged at the bottom of the ultrasonic detection probe, and the bottom of the delay block is exposed through the mounting hole; an elastic floating module is arranged in the mounting hole, so that the ultrasonic detection probe can float in the mounting hole. The ultrasonic detection device provided by the patent can automatically keep the sound beam perpendicular to the surface of the steel pipe by sliding the probe along the steel pipe, without the need for people to manually control the direction of the probe to keep it vertical, which is convenient and fast.
