How to distinguish and apply 90 degree and 45 degree elbows
Application of 90 degree and 45 degree elbows
What to pay attention to when buying elbows
In the pipeline system, elbow is a pipe fitting that changes the direction of the pipeline.
According to the angle, there are three most commonly used elbows: 45°, 90° and 180°.
In addition, according to project needs, other abnormal angle elbows such as 60° are also included.
Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics, etc.
What is a 90 degree elbow
The 90-degree elbow is the most commonly used product among elbow accessories.
It is mainly responsible for connecting pipe fittings that need to be docked.
In some cases, right-angle pipe connections are required, and only 90-degree elbow sizes can successfully complete the connection.
In the field of engineering, there are also various elbow products with different angles for selection, and the materials are rich and diverse, including metal, plastic and alloy.
What is a 45 degree elbow
A 45-degree elbow is a pipe fitting commonly used in piping systems that has an angle of 45 degrees and is used to change the direction of the pipe.
The calculation of 45-degree elbow usually involves parameters such as pipe diameter, angle, and bending radius.
