stainless steel #elbow and carbon #steelelbow angle, there are 45 ° 90 ...

The main difference between stainless steel #elbow and carbon #steelelbow is that the material is different. The chemical composition of stainless steel elbow will keep the elbow surface free from rust and corrosion for a long time.

In the pipeline system, the elbow changes the direction of the pipeline pipe fitting 。 According to the angle, there are 45 ° and 90 ° 180 ° three most commonly used, in addition, according to the needs of the project, it also includes 60 ° and other abnormal angle elbows.

Stainless steel elbow

Elbow Cast iron, stainless steel Alloy steel It can be calcined cast iron, carbon steel, nonferrous metals and plastics. The ways to connect with the pipe are: direct welding (the most common way) flange Connection Hot melt bonding , electrofusion connection Threaded connection And socket connection, etc. According to the production process, it can be divided into: Welded elbow 、 Stamping elbow 、 Hot pressed elbow 、 Push elbow Cast elbow, forged elbow, clamp elbow, etc. Other names: 90 ° elbow, right angle bend, Aier bend, white steel elbow, etc.
