Introduction to common problems of sanitary pipe fittings

Introduction to common problems of sanitary pipe fittings. There are many kinds of sanitary 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 pipe fittings.

Introduction to common problems of sanitary pipe fittings:

1. Uneven wall thickness of sanitary pipe fittings

The uneven wall thickness of sanitary pipe fittings mainly occurs in the part with the largest deformation, such as the wall thickness at the back of the elbow is thinner than other parts; The wall thickness of pipe orifice and pipe fitting body is not equal. 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 sanitary pipe fittings before delivery and after arrival

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