Welded elbow is a kind of steel elbow formed by hot pressing or forging. Its connection form is directly butt welding the elbow and steel pipe.

According to its curvature radius, butt welding elbow can be divided into long radius butt welding elbow and short radius butt welding elbow; according to the pressure grade, there are about 17 kinds, which are the same as American pipe standard; according to the angle of elbow, there are 45 degree butt welding elbow, 90 degree butt welding elbow, 180 degree butt welding elbow and other elbows with different angles; According to the material is divided into: carbon steel, alloy steel and stainless steel.

 

Classification of butt welded elbows:

(1) Butt welding elbow can be divided into long radius butt welding elbow and short radius butt welding elbow according to its curvature radius. The curvature radius of the long radius butt welding elbow is equal to 1.5 times of the pipe outer diameter, i.e. r = 1.5D. The curvature radius of the short radius butt welding elbow is equal to the outer diameter of the pipe, i.e. r = 1D. Where D is the diameter of butt welded elbow and R is the radius of curvature. If there is no special instruction, generally 1.5D elbow is selected.

 

(2) According to the pressure rating, there are about 17 kinds, which are the same as the American pipe standards: sch5s, sch10s, sch10, sch20, sch30, sch40s, STD, sch40, sch60, sch80s, XS; sch80, sch100, sch120, sch140, sch160, XXS, of which the most commonly used are STD and XS.

 

(3) According to the angle of elbow, there are 45 degree butt welding elbow, 90 degree butt welding elbow, 180 degree butt welding elbow and other elbows with different angles.

 

(4) Materials: carbon steel, alloy steel and stainless steel.
