The butt welding elbow
The material of butt welding elbow fittings in our company is mainly divided into carbon steel: ASTM/ASME A234 WPB, WPC
Alloy: ASTM/ASME A234 WP 1-WP 12-WP 11-WP 22-WP 5-WP 91-WP911, 15Mo3 15CrMoV, 35CrMoV
Stainless steel :ASTM/ASME A403 WP 304-304L-304H-304LN-304NASTM/ASME A403 WP 316-316L-316H-316LN-316TIASTM /ASME A403 WP 321-321H ASTM/ASME A403 WP 347-347H
Low temperature Steel :ASTM/ASME A402 WPL3-WPL 6
High performance Steel: ASTM/ASME A860 WPHY 42-46-52-60-65-70
The main manufacturing standard of butt welding elbow is GENERALLY GB/T13401-2005, GB/T12459-2005, ASME B16.9, SH3409, HG/T21635, HG/T21631, SY/T0510, GB/T10752-1995.
Butt welding elbows are mainly divided into:
Butt welding elbow can be divided into long radius butt welding elbow and short radius butt welding elbow according to its radius of curvature. The radius of curvature of the long radius butt weld elbow is equal to 1.5 times the outer diameter of the pipe, that is, R=1.5D. The radius of curvature of short radius butt weld elbow is equal to the outer diameter of pipe, that is, R=1D. Where D is butt welding elbow diameter and R is radius of curvature. If there is no special instructions, the general choice is 1.5D elbow.
According to the pressure grade, there are about 17 kinds of pipe standards, which are the same as those in the United States :Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, among which STD and XS are commonly used.
According to the Angle of the elbow, there are 45 degree butt welding elbow, 90 degree butt welding elbow and 180 degree butt welding elbow and other different Angle elbow.
