Stainless butt welded elbows is one type of ASTM A182 F304 pipe fittings,they are 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 90 degrees, so it is also called vertical elbow.


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.
