Introduction to the classification of stainless steel seamless elbows:
Stainless steel seamless elbows can be divided into long radius elbows and short radius elbows according to their curvature radius.
The radius of curvature of the long-radius elbow is equal to 1.5 times the outer diameter of the pipe, that is, R=1.5D, and the radius of curvature of the short-radius elbow is equal to the outer diameter of the pipe, that is, R=1D. Among them, D represents the diameter of the elbow, and R represents the radius of curvature. In general, 1.5D elbows are used.
There are about 17 types of stainless steel seamless elbows classified according to pressure grades, which are the same as the American pipe standards, including Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS, among which STD and XS are the most commonly used.
Stainless steel seamless elbows can be divided into 45° elbows, 90° elbows and 180° elbows according to the angle of the elbow.
The above is the introduction to the classification of stainless steel seamless elbows.
