What is bending?What is bend bending?What is the difference with stamping elbow

Simmer bend: refers to the pipe processing into elbow, generally refers to the water and electricity professional metal pipe and electrical PVC thread pipe;

Simmer elbow: mostly refers to the metal elbow of water supply and drainage professional. Small pipe diameter elbow can be obtained by bending;

Cold bending, hot bending: general small and medium diameter elbow can be obtained by cold bending processing;For larger pipe sizes, hot bending is required.That is, medium frequency elbow machine.Simmer bending processing generally refers to the completion of the site.Stamping elbow: most of the project water system used (especially large pipe diameter) can purchase finished elbow, processing method is stamping, product consistency is good.The elbow made by medium frequency elbow pushed by machine: in the late 1980s, I came into contact with the process of making steel elbow by using the method of machine + mold inner tube + medium frequency heating, but later, because of the difficulty in controlling the inner and outer wall thickness, it was rarely used in practice.

What is the difference between stamping elbow and ordinary elbow?

Seamless elbow and stamping elbow is not a kind of, the difference is as follows: 1, hot pressing elbow is stamping elbow, it is made of material heating with a special die stamping, small diameter;Welding elbow is "shrimp bend", it can be cut on the pipe or steel plate after welding, its specifications can be very large.The number of bends and the bending radius are determined by the creator freely.The bending radius of both is not large, which is generally about 1 times of the pipe diameter. The bending radius of the simmering bending is about 8 times of the pipe diameter, and its smoothness is also the same as that of the stamping bending.2, seamless elbow is made of pipe bending, can be welded, so it is called welding elbow, and does not mean that it has its own weld, in fact, on the contrary, welding elbow is made of straight pipe stamping and bending, taking into account the structure of the force problem generally use seamless pipe.Not welded pipe., while the so-called seamless elbow is a casting, not weldable.135
