Elbow manufacturers introduce the types and classifications of elbows  

The curvature radius of elbow can be divided into: long radius elbow and short radius elbow;  A long radius elbow has a radius of curvature equal to 1.5 times the outer diameter of the pipe, that is, R= 1.5d;  A short radius elbow has a radius of curvature equal to the outer diameter of the pipe, that is, R= 1.0d;  (D is the elbow diameter,R is the radius of curvature;  D can also be multiplied;)  

Elbow by Angle: there are 45 degrees elbow and 90 degrees elbow 180 degrees elbow three more commonly used, according to the needs of the project can also include 60 degrees and other abnormal Angle elbow  

Welding elbow press pressure rating to points: about 17 species, and the pipe standard is the same: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS;  Sch80, Sch100 Sch120, Sch140 Sch160, XXS, which is commonly used is the STD and XS two;  

Welding elbow material range:  

Carbon steel elbow is suitable for welded steel pipe, seamless steel pipe, 16Mn steel pipe.  

Stainless steel pipe is suitable for all kinds of materials except ultra low carbon stainless steel pipe.  

Carbon steel coil tube installation is suitable for 16Mn steel coil tube.  

Copper tube is suitable for pure copper, brass and bronze tube.  

The applicable scope of pipe fittings, valves and flanges refer to the pipe material.  

Alloy steel pipe is suitable for all kinds of materials except high alloy steel pipe according to the specification.
