45 ° elbow is to adopt the same as the pipe material of stainless steel sheet with stamping die stamping into half a piece of ring elbow, then two and a half ring bend group for welding.

45 ° stainless steel elbow according to its radius of curvature points: can be divided into long radius elbow and short radius elbow. The radius of the long radius is the diameter of the tube which is 1.5 times the radius of the tube, namely R= 1.5d; The radius of curvature of the short radius is equal to the diameter of the tube, which is R= 1.0d. (D is the diameter of the bend, R is the radius of curvature).

45 ° cast iron with the material of stainless steel elbow, stainless steel, alloy steel, malleable cast iron, carbon steel, nonferrous metal and plastic, etc. The way to connect the pipe is: direct welding (commonly used) flange connection, fusion connection, electric fusion connection, thread connection and socket connection, etc. According to the production process can be divided into: welding elbow, stamping elbow, pushing elbow, casting bend, etc. Other names: 90 degrees elbow, right Angle bend, love and bend etc.
