Carbon Steel Elbow Long Radius
Carbon steel elbow has two degrees:90 deg and 45 deg.In real application,90 deg is more used type.90 deg elbow can be long radius (LR) and short radius (SR) while 45 deg elbow only has long radius (LR).
Carbon steel elbow is the most normal material for elbows.90 deg elbows have two types:long radius (LR) and short radius (SR).Have to be aware of is 45 deg elbows only has LR type.
BW elbow is formed by hot forming and connects steel pipes or other pipe fittings through butt welding process. Its function is to change the direction of the fluid by 45, 90, 180 degrees.Carbon steel elbow is a commonly used pipe fitting due to its affordable price and superior function.
There are two types of BW elbows: Long radius(LR) and Short radius(SR)
Long radius ELBOW
Long radius elbow refers to the pipe outer diameter with radius of curvature equal to 1.5 times, i.e R = 1.5D.
Short radius ELBOW
Short radius elbow means that its radius of curvature is equal to the outer diameter of the tube, i.e R = 1.0D.
The end of Butt welded fittings are connected to the pipe system by butt welding.Butt weld fittings provide permanent leak-proof performance.BW fittings could made from seamless or welded pipe,and then through several processes formed to get the shape of pipe fittings.
