One-shot seamless elbow

Seamless elbow is a common connection element in pipeline system, and it is also an important equipment for changing the direction of flow in pipeline system. It is made of seamless steel pipe and has good pressure resistance and sealing performance. It is widely used in industrial production and civil construction, such as petrochemical, coal mining, electric power, shipbuilding, construction, aerospace and other industries.

First, the classification of seamless elbows

The classification of seamless elbows is mainly based on their curvature radius and elbow Angle to distinguish, of which the curvature radius is generally 1.5D, 3D, 5D and so on. The elbow Angle is generally 45 degrees, 90 degrees, 180 degrees and so on. Different curvature radii and elbow angles are suitable for different piping systems and working environments.

Second, the manufacturing process of seamless elbow

1. Material preparation: Select the appropriate seamless steel pipe as the raw material according to the design requirements.

2. Bending processing: Put the seamless steel pipe into the pipe bending machine, and bend the steel pipe into the desired shape under heating by controlling the Angle and radius of curvature of the machine.
