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