    • Process flow
    • Seamless elbow: elbow is a pipe fitting used at the bend of a pipe. The largest proportion of all pipe fittings used in the pipeline system is about 80. Usually, different forming processes are selected for bends with different materials or wall thickness. The seamless elbow forming process used by the manufacturer is hot push, stamping, extrusion and so on.
    • Folding Thermal Push
    • The forming process of hot-push elbow is the process of using special elbow pushing machine, core die and heating device to make the blank set on the die move forward under the push of the pushing machine, and be heated, expanded and bent in motion. The deformation characteristic of hot push elbow is to determine the diameter of pipe billet according to the law of constant volume before and after plastic deformation of metal material. The diameter of pipe billet is smaller than the diameter of elbow. Compensate to other parts of the inner arc thinning due to diameter expansion, thus obtaining a uniform wall thickness elbow.
    • The hot-push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness and continuous operation, which is suitable for mass production, so it has become the main forming method of carbon steel and alloy steel elbows, and has also been applied in the forming of stainless steel elbows of some specifications.
    • The heating mode of forming process includes intermediate frequency or high frequency induction heating (heating ring can be multi-ring or single ring), flame heating and reflecting furnace heating. The heating mode depends on the requirements of forming product and energy situation.
    • Folding stamping forming
    • stamping forming elbow is the earliest forming process used in batch production of seamless elbow. it has been replaced by hot push method or other forming process in the production of elbow of common specifications, but in some specifications of elbow due to less production quantity, too thick wall thickness or too thin.

    Technical requirements for folding and editing of this paragraph
    1. because most of the pipe fittings are used for welding, in order to improve the welding quality, the end part is groove, leaving a certain angle, with a certain edge, this requirement is also more strict, how thick the edge, how much angle and deviation range are stipulated. The surface quality and mechanical properties are basically the same as the pipe. For the convenience of welding, the pipe fittings are the same as the steel type of the connected pipe.
    2., all pipe fittings must be surface treated, the internal and external surface of the oxide sheet through shot peening treatment, and then coated with anticorrosive paint. This is for export needs, moreover, in the domestic is also to facilitate transportation to prevent corrosion and oxidation, to do this work.
    3. is the requirement of packing for small pipe fittings, such as export, need to make wooden cases, about 1 cubic meter, the number of bends in this box should not exceed one ton, this standard allows suits, that is, large sets and small ones. But the total weight should not exceed 1 ton. For large y, a single package, such as 24" must be a single package. Also is the packing mark, the mark is to indicate the size, the steel number, the batch number, the factory trademark and so on.
