sch40 Seamless elbow

Seamless elbow: The elbow is a pipe fitting used at the bend of the pipe. In all the pipe fittings used in the pipeline system, the proportion is large, about 80%. Usually, different forming processes are selected for elbows of different materials or wall thickness. Manufacturers commonly used seamless elbow forming processes include hot pushing, stamping, extrusion and so on.

Hot push forming: hot push elbow forming process is the use of elbow pushing machine, core die and heating device, so that the blank on the mold in the push machine to move forward, in the movement is heated, expanded and bending forming process. The deformation characteristic of hot pushing elbow is to determine the diameter of the tube billet according to the law of constant volume before and after plastic deformation of the metal material. The diameter of the tube billet is less than the diameter of the elbow. The deformation process of the blank is controlled by the core mold, so that the compressed metal flow in the inner arc can be compensated to other parts thinned by expanding the diameter, so as to obtain the elbow with uniform wall thickness. Hot push elbow forming process has the characteristics of beautiful appearance, uniform wall thickness, continuous operation and suitable for mass production, so it has become the main forming method of carbon steel and alloy steel elbow, and is also used in the forming of some specifications of stainless steel elbow.

The heating method of forming process has medium frequency or high frequency induction heating (heating ring can be multiple or single ring), flame heating and reflector furnace heating, which heating method depends on the requirements of forming products and energy situation. Stamping forming: stamping forming elbow is an early application in the mass production of seamless elbow forming process, in the common specifications of elbow production has been replaced by hot push method or other forming process, but in some specifications of elbow due to less production, too thick or too thin wall thickness. The product is still in use when there are special requirements. The stamping forming of the elbow is made of a tube blank equal to the outside diameter of the elbow, which is directly pressed by a press in the die.

Our company mainly produces seamless elbow, seamless carbon steel elbow, tee, size head, cap, bend and other types of pipe fittings.
