The origin of alloy elbow

Alloy elbow is a general category of a variety of elbow, the role is to connect the pipe bend, is to connect two pipes with the same nominal diameter, so that the pipeline to do 90° or other Angle of the turn. It is a variety of materials, alloy elbow is very widely used.

Alloy elbow is divided into long radius elbow and short radius elbow, long radius elbow refers to its radius of curvature is equal to 1.5 times the outer diameter of the pipe, namely R=1.5D. A short radius elbow has a radius of curvature equal to the outer diameter of the pipe, i.e., R=1.0D. D is the diameter of the elbow and R is the radius of curvature.

The standard difference of alloy elbow: national standard, two standard, non standard, electric standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard, Russian standard and so on.

The difference of elbow raw materials: stainless steel elbow: 304L, 316L, ASTM/ASMEA403WP304-304L-304H-304LN-304N, 310S, SUS304, 30408 and so on.

Carbon steel elbow: ASTM/ASMEA234WPB, WPC, 20#, Q235B, Q245R, A105, etc.

Alloy steel elbow: 16 manganese, Q345B, Q345R, ASTM/ASMEA234, WP1-WP12-WP11-WP22-WP5-WP91-WP911, 12CR1MOV, 15CrMoV, 35CrMoV, etc.

Alloy elbow is mainly used for connecting pipe fittings in pipeline installation, for connecting pipe corners. Connect two pipes of the same nominal size to make a 90° or other Angle turn. Alloy elbow is a general category of a variety of elbow, its material is diverse, common carbon steel, manganese steel, nickel steel and so on.
