What kind of production process of elbow is common

What kind of production process of elbow is commonly used?

The function of the elbow is to change the pipe diameter during the degree turn.With the size of the head is the same, but the size of the head can not be used to turn, the price is about twice as high as the equivalent diameter of the elbow.In some construction sites, an elbow and a small head are welded together instead of this product.Its material has carbon steel, stainless steel, alloy steel, cast steel and so on.Common standards have national standards of its main producing area in Hebei Cangzhou Mengcun.Other names of elbow: reducing 90 elbow, reducing elbow, large and small bend, special shaped elbow use: connect two pipes with different diameters, so that the pipeline for 90 turn at the same time to reduce the diameter.The production process adopted is to use the whole elbow drawing sliver shrinking process to produce.According to the process, hot push elbow, stamping elbow, welding elbow, etc.According to the material there are carbon steel elbow, stainless steel elbow, welding elbow, etc.According to the specifications: there are short radius elbow and long radius elbow, elbow of different degrees.Elbow is to use a standard elbow billet shear load into a shape of elbow, pressed and then by means of conventional or stamping equipment commonly used power, make the elbow billet deformation force and deformation in the mould is directly, thereby gaining a certain shape, size and performance of the product parts production technology, slowly under pressure is gradually into a circle, as a circular ring shell, the welding forming,Then you use the elbow device and you're done.Pipe blank, die and equipment are the three elements of reducing elbow machining.The quality of the national standard push elbow is good. The forming process of the carbon steel most valuable elbow is the most important forming production process of the elbow.

The radius of curvature of butt welding elbow

The curvature radius of butt welding elbow is divided into long radius butt welding elbow and short radius butt welding elbow.The radius of curvature of the long radius butt welding elbow is equal to 1.5 times the pipe diameter.The radius of curvature of the short radius butt welding elbow is equal to the outside diameter of the pipe.Customers in the order of elbow if there is no special instructions, the general choice is the long radius butt welding elbow.
