Alloy Steel Pipe Fittings 45Elbow A234 Grade WP91 12" X0.875" Butt Welding Elbow

Introduction to Elbows

In the pipeline system, elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three most 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 (the most commonly used method) flange connection, hot-melt connection, electric fusion connection, threaded connection and socket connection. According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc. Other names: 90 degree elbow, right angle bend, etc.
