Categories of BW elbow

The butt welding elbow can be divided into long radius butt welding elbow and short radius butt welding elbow according to its radius of curvature. The radius of curvature of the long radius butt welding elbow is equal to 1.5 times the outer diameter of the pipe, ie R=1.5D. The radius of curvature of the short radius butt welding elbow is equal to the outer diameter of the pipe, ie R=1D. D in the formula is the diameter of the butt welding elbow, and R is the radius of curvature. If there is no special instruction, the 1.5D elbow is generally used.
