How to choose the common processing method of seamless elbow

Seamless elbow is a pipe fitting used for pipe turning.The proportion of all pipe fittings used in the pipeline system is about 80%. For bending pipes with different thickness of materials, different forming processes are generally selected.Now, the common forming process of seamless elbow is hot push, stamping, kneading and so on.Seamless elbow in the production of common processing methods: rolling method: seamless elbow in the production of the general do not need a core shaft, suitable for thick wall pipe fittings.

Seamless elbow common material is seamless steel pipe.Selection methods such as water cut, eager to open cut out elbow pipe, in the selection of intermediate frequency continuous pushed to push the machine, after push type is made by hot press continuous correction, continuous groove back, nondestructive testing in the factory after the subsequent processing, such as rolling seamless elbow pipe materials are tubular billet, round tube beginning and end of the embryo to cut boot cut processing growth degree of about one meter of billet, and the pass band to heating furnace.

Because most of the pipe fittings are used for welding, in order to advance the welding quality, the requirements are strict, the thickness of the edge, the number of viewpoints and the error planning have rules.The surface quality and mechanical properties of the tube are the same.For convenience of welding, the steel of the pipe fittings and the connected pipe are the same.Is all the pipe fittings to go through the surface treatment, the surface of the oxide sheet after shot peening treatment spray off a large set of small, but the total weight generally can not cross 1 ton.For large pieces, a single package is required, and the other is the packaging symbol. The symbol is to indicate the standard, steel number, batch number, manufacturer logo, etc.

45 degree elbow manufacturers sell to all over the world

The company mainly produces 45 degree elbow, 45 degree elbow using advanced technology and equipment to produce various materials of elbow worldwide: such as Malaysia, Turkmenistan, India, Russia and so on.
