Introduction to common problems of sanitary stainless steel pipe fittings. There are many kinds of sanitary stainless steel pipe fittings, including sanitary tee, sanitary elbow, sanitary clamp, etc. Because of their advantages in the field of environmental protection and health, they are widely used in these fields, especially in flammable and explosive pipelines. However, there are also some problems in the quality of stainless steel pipe fittings. Let's take a look.

Common problems of sanitary stainless steel pipe fittings mainly include the following:

1. Uneven wall thickness of sanitary stainless steel pipe fittings

The uneven wall thickness of sanitary stainless steel pipe fittings mainly occurs in the part with the largest deformation of stainless steel pipe fittings, such as the wall thickness at the back of the elbow is thinner than other parts; The wall thickness of pipe orifice and stainless steel pipe fitting body is different. In order to detect these problems, it is not easy to detect them with common measuring tools such as caliper. At this time, they can only be detected with ultrasonic thickness gauge.

2. The problem of hardness exceeding the standard is mainly caused by the heat treatment process after forming. The solution is to conduct another heat treatment with the correct heat treatment process.

3. Inspection of stainless steel pipe fittings before delivery and after arrival

As the last process to ensure the quality of sanitary stainless steel pipe fittings, inspection plays an important role, especially for stainless steel pipe fittings that are subject to high temperature, high pressure and flammable and toxic media.
