 General application of the flange on the pressure vessel, are not allowed to cast flanges, must be forged flanges. Because the

casting flange to withstand greater pressure, prone to leakage. National standards in accordance with the pipe flanges and chemical

industry standards, casting flange only on the overall flange. Casting flange is definitely more economical. Workpiece internal part of

defective lamination formed in the forging process can casting process, forging process, or the deformation process, make a thick cast-

like organization to fight the fine and recrystallization, combined with subsequent heat treatment, so its mechanical properties,

especially toughness has improved greatly .

Forged flanges and cast flanges processing, the former forging, which uses the casting. Commonly used flanges are generally forged.

Forging better performance than the casting performance. Forging its microstructure should be more uniform mechanical properties will be

better. But forging whether there will be limitations. For example, flange size, flange shape complexity. Whether there will be some of

the flange is not suitable for forging. Forging heat treatment after forging good. This is the performance of the flange is forged and

cast flanges performance difference. Finished the allowable stress, and the casting flange is generally used for device interface

flange.

Cast flanges contain toxic level may not be used for extremely high or medium hazard media, as well as the design pressure greater than

or equal to 0.15MPa flammable media pressure vessel, shall not be used for shell and tube heat recovery boiler and mobile pressure

vessels; and forged flanges do not have this restriction. Laminated, the internal organization of forging can material defect density

increases, the internal organization of more uniform and continuous, making its mechanics performance has improved greatly.

There are many different forged flanges and cast flanges in the production process, production and processing in accordance with their

production, their production of flange to ensure good product quality and value in use, full of good performance .
