Seamless elbow
Seamless elbow in carbon steel elbow: Seamless elbow is a kind of pipe turning. In the pipe system used in all pipe fittings, about 80%. Generally speaking, for different data or wall thickness of the elbow to choose different forming technology. Manufacturers commonly used seamless elbow forming process has hot push, stamping, extrusion and so on.
Hot push forming hot push elbow forming process is the use of common elbow push machine, core die and heating installation, so that the billet set on the mold in the push machine to move forward, in the movement of heating, expanding and bending forming process. The deformation characteristic of hot push elbow is to determine the diameter of tube blank according to the law of constant volume before and after plastic deformation of metal data.
The diameter of the tube blank is smaller than the diameter of the elbow, and the deformation process of the blank is controlled by the core mold, so that the metal activity in the inner arc is tightened, and the other parts are reduced due to the expansion of the diameter, so as to get the elbow with the average wall thickness. The forming technology of hot push elbow has beautiful appearance, even wall thickness and continuous operation.
Suitable for mass consumption characteristics, so it has become the main forming method of carbon steel, alloy steel elbow, and also used in the forming of some specifications of stainless steel elbow. The heating method of the forming process has medium frequency or high frequency induction heating (heating ring can be many or single ring), flame heating and reflector heating, using that kind of heating molding process please our sales staff say clear molding process.
