Seamless elbow wall thickness error standard

The seamless elbow is one of the common connecting elements in the pipeline system, its function is to change the flow direction and velocity of the pipeline. When using seamless elbows, the error standard of wall thickness is very important, because it directly affects the service life and stability of seamless elbows. The following is a detailed introduction to the wall thickness error standard for seamless elbows.

1. Definition and classification of seamless elbows

A seamless elbow is a pipe connection element used to change the flow of a pipe. According to the curvature radius of the elbow and the bending Angle of the elbow, seamless elbows can be divided into different types, such as long radius elbows, short radius elbows and special elbows.

2. Definition and influence of wall thickness error

The wall thickness error refers to the difference between the actual wall thickness and the design wall thickness of the seamless elbow. The wall thickness error directly affects the strength and pressure resistance of the seamless elbow. Excessive wall thickness error may cause stress concentration in the elbow during use, which reduces the service life of the elbow and even causes failure.
