Production methods can be divided into pushing, pressing, forging, casting and so on.
According to the manufacturing standard, it can be divided into GB standard, electric standard, ship standard, chemical standard, water standard, American standard, German standard, Japanese standard, Russian standard, etc.
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; Short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R= 1.0d. (D is elbow diameter, R is radius of curvature).
According to the pressure grade, there are about 17 kinds of tubes, which are the same as American standards, including Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS The two most commonly used are STD and XS.
According to different shapes and uses, it can be divided into: groove elbow, card sleeve elbow, double socket elbow, flange elbow, reducing elbow, fixed seat elbow, internal and external tooth elbow, stamping elbow, push elbow, socket elbow, butt welding elbow, inner wire elbow and so on.
