It can be divided into pushing, pressing, forging, casting and so on. The manufacturing standard can be divided into national standard, electric standard, ship standard, chemical standard, water standard, n Standard, German standard, Japanese standard, Russian Standard and so on. According to its curvature radius: can be divided into long radius elbow and short radius elbow. A long-radius elbow is the outer diameter of a tube with a radius of curvature equal to 1.5, or r = 1.5 D; a short-radius elbow is the radius of curvature equal to the outer diameter of the tube, or r = 1.0 d. (d is the elbow diameter, r is the radius of curvature) . According to the pressure level: there are about 17, and the United States of pipe standards are the same: Sch5s, Sch10s, SCH10, SCH20, SCH30, Sch40s, STD, SCH40, Sch60, Sch80s, XS; SCH80, SCH100, Sch120, SCH140, Sch160, xxs; SCH100, SCH140, Sch160, XS; SCH100, Sch160, XS; SCH100, SCH140, Sch160, XS; Sch10s, Sch160, XS; Sch10s, the two most commonly used are STD and XS. According to different shapes, it can be divided into: Groove type elbow, clip type elbow, double bearing elbow, flange elbow, reducing elbow, sitting elbow, internal and external teeth elbow, stamping elbow, push elbow, socket elbow, butt welding elbow, internal wire elbow, etc. .
