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:
