Some problems in the quality and wall thickness of stainless steel pipes:

1. The wall thickness of Stainless Steel Weld Fittings is uneven. The unevenness mainly occurs at the position where the stainless steel pipe is deformed more, such as the wall thickness of the back of the bend is thicker than other positions: the thickness of the branch pipe and the stainless steel pipe body is different. In order to detect these problems, it is difficult to detect them with common measuring instruments such as vernier calipers. At this time, only ultrasonic coating thickness gauges can be used to measure them.

2. Quality exceeds the standard: The problem of strength exceeding the standard is mainly caused by the problem of heat treatment after forming. The solution is to use the appropriate heat treatment method to carry out another heat treatment process.

3. Inspection of stainless steel pipes before leaving the factory and after delivery: For the final process to ensure the quality of sanitary stainless steel pipes, inspection plays a key role, especially for stainless steel pipes that bear ultra-high pressure and flammable and toxic substances, the inspection process is crucial.
