The common problems with sanitary grade stainless steel fittings are as follows:
1. Uneven wall thickness of sanitary grade stainless steel fittings
The uneven wall thickness of sanitary grade stainless steel pipe fittings mainly occurs in the parts where the stainless steel pipe fittings deform significantly, such as the wall thickness on the back of the elbow being thinner than other parts; The wall thickness of the pipe mouth and the stainless steel pipe fitting body is not equal. To detect these issues, commonly used measuring tools such as calipers are not easy to detect, and only ultrasonic thickness gauges can be used to measure them.
2. Hardness exceeds the standard
The problem of excessive hardness is mainly caused by the heat treatment process after forming, and the solution is to use the correct heat treatment process for another heat treatment.
3. Inspection of stainless steel pipe fittings before leaving the factory and after arrival
For the final process of ensuring the quality of sanitary grade stainless steel fittings, inspection plays an important role, especially for stainless steel fittings that can withstand high temperature, high pressure, and flammable and toxic media. The inspection process is particularly important.
