There are mainly the following, specifically:
1. Uneven wall thickness of sanitary stainless steel pipe fittings
The uneven wall thickness of sanitary stainless steel pipe fittings mainly occurs in the parts where the stainless steel pipe fittings are deformed , such as the wall thickness of the back of the elbow is thinner than other parts; the wall thickness of the nozzle and the body of the stainless steel pipe fittings varies.
To check these problems, it is not easy to detect common measuring tools such as calipers. At this time, only ultrasonic thickness gauges can be used.
2. Hardness exceeds standard
The problem of excessive hardness is mainly due to the heat treatment process after forming. The solution is to use the correct heat treatment process to perform another heat treatment.
3. Inspection before and after delivery of stainless steel pipe fittings
As a process to ensure the quality of sanitary stainless steel pipe fittings, inspection plays an important role, especially for stainless steel pipe fittings that withstand high temperature and pressure and flammable and highly toxic media, the inspection process is particularly important.
