Manufacturing Processes

The forging process generally consists of the following steps:

         Selecting high-quality billet blanking

         Heating

         Forming

         Forging

         Cooling

Flanges are parts that connect pipes to pipes and valves, and are connected to the pipe ends; flanges are also used on the inlet and outlet of equipment, and are used to connect two devices. They are parts that connect pipes to pipes. at the pipe end. It is an accessory product for pipelines.

Forged flanges have better pressure resistance and temperature resistance, and are generally suitable for working environments with high pressure and high temperature.

Forged steel flange has higher precision and performances, it's widely used in different industries for connecting equipment or pipelines, especially for high temperature and high pressure environments.

Forged flange is a plate-type device, usually in circular appearance which could be attached the ends of pipes, fittings, valves or other objects to facilitate assembly and dis-assembly of the piping system. It offers impressive mechanical performance as a connecting parts.

Forged Steel Flange

     It has good streamline shape and compact structure, have good mechanical properties.

     If the forging process is improper, the grain will be large or uneven, and the hardening crack will occur.

     Forgings is compatible with high shear and tensile forces.

     The internal structure of the forging is uniform.

Forged Steel Flange Advantages

      Good pressure resistance

      Good temperature resistance

      Excellent durability

      Easy for installation

Technology and Method of Forging Steel FlangeIts technology and method includes free forging, die forging and fetal membrane forging. According to the quality of the forgings and number of production batches, different forging methods are selected.

Free Forging

The free forging productivity is low, the machining allowance is large, but the tool is simple and the versatility is large, so it is widely used for forging a single piece and a small batch of forgings with a simple shape.

Die Forging

The die forging is collectively referred to as model forging, in which the heated blank is placed in the forging die fixed on the die forging equipment.

What is the difference between cast flange and forged flange?

Forged and casted flanges are both frequently utilized flanges, however forged flanges are less expensive and have more exact approximate shapes and sizes. However, casted flanges have casting faults and fissures.
