Carbon Steel Elbow

Carbon steel elbow is a metal pipe fitting that changes the direction of the pipe on carbon steel pipe.The connection is made by wire fastening and welding.Points according to the Angle 45 ° and 90 ° 180 ° three most commonly used, according to the requirements of the project also includes 60 °, and other abnormal Angle bend.The bending materials include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metal and plastics.The pipe is connected by direct welding (most commonly used) flange connection, hot-melt connection, electric welding connection, threaded connection and socket connection.According to the production process can be divided into: welding elbow, stamping elbow, pushing elbow, casting elbow, etc.Other names: 90 degrees bend, right Angle bend, love and so on.

classification

Carbon steel elbow is first divided into long radius elbow and short radius elbow by its radius of curvature.Long radius elbow means that its radius of curvature is 1.5 times the outer diameter of the pipe, or R=1.5D.Short radius elbow means that its radius of curvature is equal to the outside diameter of the pipe, which is R=1.0D.(D is the diameter of the elbow and R is the radius of curvature.D can also be expressed in multiples.According to the pressure level, there are about 17 kinds of pipes, which are the same as the American pipe standard, including: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s and XS.Sch80, Sch100, Sch120, Sch140, Sch160, XXS, the two most commonly used are STD and XS.According to bend Angle, has 45 ° elbow, and 180 ° 90 ° elbow bend.The implementation standards include GB/ t12459-2005, GB/ t13401-2005, GB/ t10752-1995, HG/ t21635-1987, d-gd0219, etc.

Scope of application

Due to the stamping elbow has good comprehensive performance, so it is widely used in chemical industry, building, water supply, water drainage, oil, light and heavy industry, frozen, sanitary, plumbing, fire protection, electric power, aerospace, shipbuilding and other basic engineering.
