Carbon Steel Elbow

2018-10-10

Introduction: Carbon steel elbows are made of carbon steel elbows and are two large-diameter pipes connecting devices. It is usually composed of two elbows plus several fastening bolts. It is a metal pipe that changes the direction of the pipe on the carbon steel pipe.

Classification and application range of carbon steel elbows

A Carbon Steel Elbow is an elbow made of carbon steel and is a connection device for two large-diameter pipes. It is usually composed of two elbows plus several fastening bolts. It is a metal pipe that changes the direction of the pipe on the carbon steel pipe. Low-carbon steels have low plastic strength, they become hard after adding appropriate amounts of carbon, and plasticity reduces the strength. Elbow joints may need to withstand high tensile, compression, torsion, and shear strengths. Carbon steel elbows are a better choice.

Carbon steel elbow classification

Carbon steel elbows are divided according to the radius of curvature and can be divided into long radius elbows and short radius elbows. The long-radius elbow refers to its radius of curvature equal to 1.5 times the outer diameter of the tube, ie R = 1.5D. A short-radius elbow means that its radius of curvature is equal to the outer diameter of the tube, ie R = 1.0D. (D is the elbow diameter, R is the radius of curvature. D can also be expressed in multiples.)

Carbon steel elbows are divided according to pressure rating, there are about 17 kinds, and the United States tube standard is the same, there are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80 , Sch100, Sch120, Sch140, Sch160, XXS, the most common of which are STD and XS.

The elbow of carbon steel is divided by the angle of the elbow, with a 45° elbow, a 90° elbow and a 180° elbow. The implementation of the standards are GB/T12459-2005, GB/T13401-2005, GB/T10752-1995, HG/T21635-1987, D-GD0219 and so on.

Carbon steel elbows are divided according to their technological forms, which can be divided into welding elbows, stamping elbows, and casting elbows.

Carbon steel elbow application range

The production of carbon steel elbows is relatively simple and is mainly applied to pipeline systems with corrosive media. Elbows and flat rings can be made of different materials to reduce the cost of the elbows and improve performance. Its good performance advantages, can guarantee important use performance and operational contribution, widely used in thermal power, steel, smelting, cement, machinery, coal, mining, chemicals, ports and other industries.
