The use of elbows in industry:
In the duct system, the elbow is a pipe that changes the direction
of the duct.
According to the angle, there are 45° and 90°180° which are the
most commonly used. 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,
forgeable cast iron, carbon steel, non-ferrous metals and plastics.
There are ways to connect with the pipe: direct welding (the most
common way) flange connection, threaded connection and socket type
connection.
According to the production process, it can be divided into:
welding elbow, stamping elbow, casting elbow, etc.
A commonly used connection pipe fitting in pipeline installation,
used to connect the pipe bend.
Other names: 90 degree elbow, right angle bend, love and bend, etc.
The purpose of the elbow: to connect two pipes with the same
nominal diameter to make a 90-degree turn.
