Carbon steel pipe fitting is a widely used pipe fitting product at present. The main materials are q235 20#, 35#, 45# and 16mn.

The main products include carbon steel elbow, carbon steel flange, carbon steel tee, carbon steel tee, carbon steel reducing pipe (size head), carbon steel head (cap), etc. The main implementation standards include national standards, American standards, and Japanese standards, among which national standards also include the standards of the ministry of chemical industry, sinopec pipe fitting standards, and electric power pipe fitting standards.

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

Scope of application:

Due to its good comprehensive performance, carbon steel pipe fittings are widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, freezing, sanitation, water heating, fire control, electric power, aerospace, shipbuilding and other basic projects.
