Basic process and process form of carbon steel elbow

The basic process of carbon steel elbow is: first of all, a polygonal circular shell or polygonal fan-shaped shell closed at both ends is welded. After the internal pressure medium is filled, internal pressure is applied. Under the action of internal pressure, the cross-section gradually becomes a circle from the polygon, and finally becomes a circular circular shell.According to the needs, a circular annular shell can be cut into 4 90° elbows or 6 60° elbows or other specifications of the elbow, this process is suitable for making the middle diameter of the elbow and the inner diameter of the elbow ratio is more than 1.5 times of any specification of large elbow, is currently an ideal method for manufacturing large carbon steel elbow.

Carbon steel material can be divided into :10# 20# A3 Q235A 20G Q345B 20G 16MN ASTM A234 ASTM A105 ST37 ASTM A403, etc.

According to the Angle points: 45°, 90°, 180° these three commonly used elbow, and other engineering needs, can be specially customized such as 60° or other angles.

Connection mode with carbon steel pipe: welding, flange connection, threaded connection, socket connection and so on.

According to the process form can be divided into: welding elbow, stamping elbow, casting elbow and so on.

Purpose: Connect two pipes, make the pipe change direction, 45° or 180° and 90° direction or other angles turn.
