welding 90° elbow 

90° Welding elbow  ASTM A234 WPB

English (Welded butt welding elbow here) are steel hot-pressing molding or bend forging forming, its connection form is directly to the elbow and the steel pipe butt welding, butt welding elbow's main manufacturing standards are generally GB/T13401-2005, GB/T12459-2005, ASME B16.9, SH3409, HG/T21635, HG/T21631, SY/T0510, GB/T10752-1995.
 
 
 
 
The butt welding elbow classification
 
 
(1) the butt welding elbow press its radius of curvature to points, can be divided into the butt welding elbow butt welding elbow long radius and short radius.Long radius butt weld bend radius of curvature is equal to 1.5 times the pipe diameter, R = 1.5 D.Short radius butt weld bend radius of curvature is equal to the pipe diameter, R = 1 d.Type D for butt welding of bend diameter, R is the radius of curvature.If no specific instructions, general selection is 1.5 D bend.
 
 
If (2) according to the grades of pressure points, about seventeen, and American standard pipe is the same, there are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS;Sch80, Sch100, Sch120, Sch140, Sch160, XXS, one of the most common is two kinds of STD and XS.
 
 
(3) according to bend Angle points, butt welding elbow has 45 degrees, 90 degrees 90 degrees of butt welding elbow and butt welding elbow bend and other different angles.
 
 
(4) material: carbon steel, alloy steel and stainless steel.
