Types Of Elbow

In the pipeline system, the elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three most commonly used ones: 45° and 90°180°. In addition, according to engineering needs, it also includes other abnormal angle elbows such as 60°. The elbow materials are cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics.

The ways to connect with the pipe are: direct welding (the most common way) flange connection, hot melt connection, electrofusion connection, threaded connection and socket connection, etc. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle bend, etc.

A commonly used connection pipe fitting in pipeline installation, connecting two pipes with the same or different nominal diameters to make the pipe bend at a certain angle, and the nominal pressure is 1-1.6Mpa.

The elbow is a commonly used connection pipe fitting in plumbing installation, used for the connection of the pipe bend, and used to change the direction of the pipe.

Other names: 90° elbow, right angle bend, love bend, stamping elbow, pressed elbow, machine elbow, welding elbow, etc.

Purpose: To connect two pipes with the same or different nominal diameters, so that the pipeline can be turned at 90°, 45°, 180° and various degrees.

A bending radius less than or equal to 1.5 times the pipe diameter belongs to an elbow, and more than 1.5 times the pipe diameter belongs to an elbow.
