How to cut a steel pipe into a 90 degree elbow

　　The steel pipe automatic cutting machine has low cost. One person can operate multiple machines at the same time. It makes employees' work easy, unmanned automatic operation, fast cutting without secondary processing, no burrs, no deformation, narrow cutting slits, and high precision.

　　Cut the steel pipe into two sections by drawing a line along the 45-degree direction of the steel pipe axis. Rotate one section 180 degrees in the radial direction, then align the two cutting surfaces and weld them to form a 90-degree elbow.

　　Elbows are pipe fittings that change the direction of a pipeline. According to the angle, there are three most commonly used elbows: 45°, 90°, and 180°. In addition, according to project needs, other abnormal angle elbows such as 60° are also included. Elbow materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals and plastics, etc.

　　The methods of pipe connection include: direct welding (the most common method) flange connection, hot melt connection, electrofusion connection, threaded connection and socket connection, etc.

　　Elbow is a commonly used connecting pipe fitting in plumbing installation. It is used to connect pipe corners and change the direction of pipes. 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, love bend, etc. Other names: 90° elbow, right-angle bend, love bend, stamping elbow, pressed elbow, machine-made elbow, welding elbow, etc.

　　Purpose: Connect two pipes with the same or different nominal diameters to make the pipelines turn at 90°, 45°, 180° and various degrees.

　　A bending radius less than or equal to 1.5 times the pipe diameter is an elbow, and a bending radius greater than 1.5 times the pipe diameter is an elbow.
