1: Uneven wall thickness of 304 stainless steel pipe fittings
The uneven wall thickness of 304 stainless steel pipe fittings mainly occurs in the parts of the stainless steel pipe fittings with the largest deformation, such as the wall thickness of the back of the elbow is thinner than other parts; The wall thickness of the nozzle is not equal to that of the stainless steel pipe fitting body. To check out these problems, calipers and other commonly used measuring tools are not easy to detect, at this time only the use of ultrasonic thickness measurement instrument can be measured.

2: Hardness Excessive
The problem of hardness exceeding standard is caused by the heat treatment process after forming.The solution is to use the correct heat treatment process to carry on the heat treatment again.

3:Inspection of 304 stainless steel pipe fittings before delivery and after arrival
In order to ensure the quality of 304 stainless steel pipe fittings in the last process, inspection plays an important role, especially for the stainless steel pipe fittings under high temperature and high pressure and flammable and highly toxic medium inspection process is particularly important.
