What are the common problems with sanitary-grade stainless steel pipe fittings
There are many types of sanitary-grade stainless steel pipe fittings, including sanitary-grade elbows, sanitary-grade tees, sanitary-grade clamps, etc. Due to their certain advantages in the field of environmental protection and hygiene, they are widely used in these areas, especially in flammable and explosive pipelines. However, there are also some quality issues with sanitary-grade stainless steel pipe fittings. Let's take a look together.
Uneven wall thickness of sanitary-grade stainless steel pipe fittings
The uneven wall thickness of sanitary-grade stainless steel pipe fittings mainly occurs at the parts where the stainless steel pipe fittings deform the most, such as the back of the elbow where the wall thickness is thinner than other parts; the wall thickness at the pipe opening is different from that of the stainless steel pipe fitting body. To detect these problems, the commonly used measuring tools like calipers are not easy to detect them. At this time, only an ultrasonic thickness gauge can measure it.
2. Excessive hardness
The problem of excessive hardness mainly arises from the heat treatment process after forming. The solution to this issue is to conduct another heat treatment using the correct heat treatment process.
Therefore, to ensure the quality of sanitary-grade stainless steel pipe fittings, inspection plays a crucial role. Especially for stainless steel pipe fittings that are subjected to high temperatures, high pressures, and flammable and toxic media, the inspection process is particularly important.
