Detailed introduction

In a piping system, an elbow is a fitting that changes the direction of the pipeline. According to the angle, there are three commonly used Z angles: 45 ° and 90 ° and 180 °. In addition, according to engineering needs, there are also other abnormal angle elbows such as 60 °. The materials of elbows include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics. There are several ways to connect pipes, including direct welding (commonly used in Z), flange connection, hot melt connection, electric fusion connection, threaded connection, and socket connection. According to production processes, it can be divided into: welded elbow, stamped elbow, push elbow, cast elbow, butt welded elbow, etc. Other names: 90 degree elbow, right angle bend, love bend, etc.

Other names: 90 ° elbow, right angle elbow, Love bend, stamped elbow, pressed elbow, machine made elbow, welded elbow, etc.

Usage: Connect two pipes with the same or different nominal diameters to make turns of 90 °, 45 °, 180 °, and various degrees in the pipeline.

Bending radius less than or equal to 1.5 times the pipe diameter is considered an elbow, while bending radius greater than 1.5 times the pipe diameter is considered an elbow
