Product Description

Flange is the main connection of pipes, pipe fittings equipment when construction tools, connect two pipes or pipe fittings equipment together.Two flange end face sealing surface, also called the water table.Runs above the seal groove, also called sealed water line, combined with the flange surface mat, after docking with the flange bolts or double stud will pipe tightly together, fixed, is the main purpose of the flange.


Forging flange of main processing technology of free forging, it is the use of force or pressure in the arrival of the iron metal in between the free deformation, not subject to any restrictions and obtain the required shape and size and certain mechanical property of forging a processing method.The advantage of the free forging is: simple tools and equipment used, high universality and low cost.Forging flange eliminates the blowhole defects, make blank has higher mechanical properties.Shortcomings: because it is manual control, so the flange forging precision low, machining allowance, labor intensity, low productivity.


Hebei JiMeng high-pressure flange pipe group co., LTD. Of free forging equipment mainly air hammer and simple structure, less investment board hammer of the two.Air hammer tonnage is small, generally is 40 kg to 750 kg, we usually use it to smaller flange forging specification products;Board hammer impact generated by using their own fall to the forging flange, large tonnage, can forging flange products of 0.3 T - 0.7 T.


Basic free forging process including upsetting, long pull, punching, cutting, bending, torsion, moving, welding process, etc.Flange forging used to have upset and punching process.


Upset: after the billet heating, one end is placed within the drain cap or tire mold, plastic deformation limit this part, and then the other end of the hammer block, upsetting forming, the flange of the product, so that we can mass production need save production time.


Punch: flange in the middle is hollow, so use punching technology.The thickness of the small flange blank single punching method can be used punching;Specifications of the flange blank double punching method must be used.
