Knowledge about the Elbow

If classified in accordance with the material, it might be classified into carbon steel elbow, cast steel elbow, alloy steel elbow, stainless steel elbow, copper elbow, aluminum alloy elbow, plastic elbow, PVC elbow and PPR elbow, and so on. The elbow is used in the turning point in connecting the pipe. When the pipe is installed, it truly is used to connect the pipe with the same diameter or with the distinct diameter to make the pipeline turn at a specific angle. Of all of the pipe fittings employed in the pipeline system, it accounts for the very best percentage with about 80%. Usually, the pipe elbow of different material or different wall thickness varies in processing. Classification Classified based on the angle, you'll find 3 commons, that is the 45°elbow, the 90°elbow and the 180°elbow. In addition, there are other styles of uncommon angle elbows, including the 60°elbow, as a consequence of the engineering needs. The material for making the elbow includes cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, nonferrous metal and plastic. The connecting way includes welded joint (The most frequent way), flange connection, thermal welded joint, electrofusion welding, threaded joint and bell and spigot joint. Classified according to the processing, it might be classified into welded elbow, stamping elbow, pushing pipe elbow and casting elbow, and so forth. Other kinds of elbows involve ninety degree elbow, square elbow, etc. Classified as per the machining way, it could be classified into pushing elbow, seamless elbow, forged elbow and casting elbow, etc. Classified in accordance with its radius of curvature, it might be classified into long radius elbow and short radius elbow. Long radius elbow means its radius of curvature is 1.five times of the diameter of pipe, that is R=1.5R. Short radius elbow means its radius of curvature equals to the diameter of the pipe, that is R=1.0D. (D refers to the diameter of the elbow and R refers to radius of curvature.) If classified in accordance with its application goal, it includes groove elbow, socket elbow, sanitary elbow, flanged elbow, decreasing elbow, street elbow, stamping elbow, pushing elbow, bell and spigot elbow, butt welded elbow, and women thread elbow. If classified in line with the level of the pressure, it involves 17 categories, such as Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS;Sch80, SCH100, Sch120, Sch140, Sch160 and XXS. Among them, STD and XS are the most frequent.
