The connection of forged flange is to fix two pipes, pipe fittings or equipment separately on a flange plate first, between two flanges, add flange gasket, fasten together with bolts, and complete the connection. Some of the pipe and equipment has been equipped with flanges, is also a flange connection. Flange connection is an important connection method for pipeline construction.

Flange on the cathodic protection of pipeline network of floor building valve should be potential and fragmentation (area) isolation of buried pipe valve used in butt welding flange forging flange connection is convenient to use, can withstand greater pressure Carbon steel flanges flanges all at the same time in the two surfaces in the surrounding use of bolt connection closed connection parts, but this connection is only a partial equipment.

And water pumps, such as forging flanges, bad call pump flange parts "if in a boiler room or production site, the flange connection of pipes and equipment are everywhere low-pressure flange small diameter wire, high pressure and low pressure of large diameter used welding forging flange, the thickness of the flange and the connection of different pressure is different bolt diameter and number of flat welding casting flange can only be used in most 16 kg, normally used in 10 kg or 6 kg of the pipe.

According to the professional engaged in flange forging products professionals point out that installed on the end of the pipe female thread to cover the pipe fitting. Used to seal the pipe line, the same as the pipe plug, dustproof, waterproof, corrosion-proof. The plasticity of the plastic itself makes the cap have strong mechanical strength, strong sealing, good chemical stability, light weight, thermal insulation, sound insulation, shock resistance, and high specific strength.

The two sealing surfaces of the bolts squeeze each other on the flange gaskets to form a seal, but this also causes damage to the seal. In order to maintain the seal, the bolt has to maintain a large force, for which the bolt has to be made larger. Larger bolts need to match larger nuts, which means larger bolts need to create conditions for tightening nuts.
