How to divide the radius of curvature of seamless elbow

When ordering seamless elbow pipe fittings, the customer should first make it clear that the seamless elbow pipe fittings ordered are long radius seamless elbow or short radius seamless elbow. Generally, the default seamless elbow pipe fittings are long radius seamless elbow pipe fittings.

The following is a brief introduction of seamless elbow according to its radius of curvature, can be divided into long radius elbow and short radius elbow. The curvature radius of the long radius elbow is equal to 1.5 times the outer diameter of the pipe, i.e., R=1.5D. The radius of curvature of the short radius elbow is equal to the outer diameter of the pipe, i.e., R=1D. Where D is elbow diameter and R is curvature radius. In the absence of special instructions, 1.5D elbows are generally selected.

If divided according to the pressure level, there are about 17 kinds of pipe standards, which are the same as those of the United States, including Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, among which STD and XS are commonly used.

According to the Angle of the elbow, there are 45 degree elbow, 90 degree elbow and 180 degree elbow.

Materials: carbon steel, alloy steel and stainless steel.
