Steel pipe pressure test device and its test method

Abstract

A steel pipe pressure test device, comprising a support frame, the front and rear sides of the support frame are respectively connected with a loading frame and a material unloading frame, a positioning fixture is installed on the support frame, and a feeding translation frame is installed between the positioning fixture and the loading frame, A water tank is installed at the bottom of the support frame, and a fixed water pressure head is installed on the left end of the support frame. The fixed water pressure head is connected with a water pressure accumulator and a head. There is a drainage system and a head; the structure mainly includes automatic loading and unloading, and a water pressure head for simultaneous detection of multiple steel pipes is installed between the loading and unloading, and the quality of the steel pipes is tested by high-strength water pressure. Multiple steel pipes are detected at the same time to improve work efficiency. Therefore, an automatic structure for simultaneous positioning and simultaneous feeding of multiple steel pipes is configured to double the work efficiency, and the automatic operation reduces the labor intensity of employees.

Description

technical field [0001] The invention relates to the technical field of steel pipe detection, in particular to a steel pipe pressure-resistant detection device and a detection method thereof.

[0002] At present, steel pipes are the most widely used steel products, and their quality directly affects economic benefits and personnel safety. Therefore, the quality inspection of steel pipes is particularly important. Now there are many methods of non-destructive testing for strict testing. , in the process of flaw detection, it is necessary to automatically feed the flaw detector. The existing feeding device will cause inconvenient and unstable feeding during the feeding process.

Moreover, most of the existing technologies use air pressure to detect whether there is damage to the steel pipe. However, compared with water pressure, the pressure generated by the air pressure is small, and the damage may not be detected, and only one steel pipe can be detected at a time, so the work efficiency is low. At the same time, employees manually install on the detection equipment, and it is inevitable that inaccurate positioning and installation errors will lead to detection failure during the installation process. At the same time, the workload of employees is also very large.
