Description
Blind flange is like a flange cover, also called blind disk or flanged pipe plug. Blind flange has no holes in the center, for to seal the pipe opening. So it's function is the same as the pipe plug or the pipe cap. The difference is blind flange is a detachable equipment, easy to replace or do maintenance.
Forged flanges combine two separate machinery parts together. They can be an extension to a structure in order to make the object stronger. Industrial flanges have numerous uses including connecting sheets, pumps, pipes and structures that specifically require an intermediate point of connection.

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.

Technology and Method of Forging Steel Flange
Its 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.
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.
