Alloy Steel A234 WP12 90 Degree Long Radius Elbow 20 Inch SMLS Butt Weld
A234 WP12 CL1 Alloy Steel Pipe Elbow Long Radius SMLS 20 Inch 90 DEG Wrought
Elbow is a fitting that changes the direction of a pipe run. According to the angle, there are three commonly used elbows: 45 ° and 90 ° 180 °, and other abnormal angle elbows such as 60 ° are also included according to the needs of the project. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics. The connection methods with pipes include: direct welding (commonly used) flange connection, hot-melt connection, electric fusion connection, threaded connection, socket connection, etc. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc.
Purpose: connect two pipes with the same or different nominal diameter to make the pipeline turn 90 °, 45 °, 180 ° and various degrees.
Pipe fittings are divided by standards and materials:
