elbow in the piping system, the elbow is to change the pipe direction of the tube. Angle points, 45 ° and 90 ° 180 °, the three most commonly used, In addition, according to the project need to include other non-normal angle of 60 ° and other elbow. The Elbow materials of cast iron, stainless steel, alloy steel, forging cast iron, carbon steel, nonferrous metals and plastics. Links with the tube: soldered directly to the most commonly used flange connection, hot melt connection, fused connection, connection and socket type connection. In accordance with the production process can be divided into: welding elbow, punch, elbow, push the system elbow, casting elbow. Other names: 90-degree elbow, right angle, love bend. To the division of production methods can be divided into push the system, pressing, forging, casting and so on. (3) can be divided into GB, standard electric, water standard, American standard, German standard, Japanese standard, the Russian standard, such as the division of manufacturing standards. Its radius of curvature: can be divided into long-radius elbows and short radius elbow. The long radius bend radius of curvature is equal to 1.5 times the outer diameter of the tube, ie, R = 1.5D. The short radius bend radius of curvature is equal to pipe diameter, R = 1.0D. D is a elbow diameter, R is the radius of curvature of the main products, insulation elbow 
 , Seamless elbow elbow socket, new materials, wear-resistant elbow, elbow hot pressing, pushing the system elbow, butt welding seamless elbow, stainless steel stamping elbow variety of materials high in the low pressure elbow , Bend.
