Uses: Connect two pipes with the same nominal diameter or different diameters to make the pipe turn at a certain angle.
1 Divided into materials: carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, etc. (However, Xiaomuchangzi is pure forging)
2 According to the production method, it can be divided into: pushing, pressing, forging, casting, etc. (Now it is generally pure forged)
3 According to manufacturing standards, it can be divided into: national standard, electric standard, water standard, American standard, German standard, Japanese standard, etc.
4 According to its radius of curvature: it can be divided into long radius elbow and short radius elbow. The long radius elbow refers to the outer diameter of the pipe whose radius of curvature is equal to 1.5 times, that is R = 1.5D. The short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, ie R = 1.0D. (D is the diameter of the elbow, R is the radius of curvature).
5 If divided by pressure level: there are about 17 kinds, 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; the most commonly used are STD and XS.
