The use and function of forged flanges

In the current industrial production industry, forged flanges are the most widely used and most effective products in industrial production. In the application, forged flange products have good corrosion resistance, and forged flanges can be connected. Various pipes. Therefore, it has been favored by most users. So, how much do you know about the role and use of forged flange products? See how the following is introduced.

The connection of the forged flange is to fix the two pipes, pipe fittings or equipment on one flange first, between the two flanges, and the flange pad, bolted together to complete the connection. Some fittings and equipment have their own flanges and are also flanged. Flange connection is an important connection method for pipeline construction.

The flange is used in the building valve of the cathodic protection transmission pipe network and the buried pipe valve well which needs to be separated by the potential piece (zone). It is convenient to use the butt flange forging flange connection, and can withstand large The pressure carbon steel flange is a joint part that is closed at the same time by bolting on both sides, but this connection is only a part of the equipment.

For example, forging flanges and pumps, it is not good to call the pump "flange parts". If it is in a boiler room or production site, there are flanged pipes and equipment everywhere. Both the low pressure and the large diameter are welded forged flanges. The thickness of the flanges of different pressures and the diameter and number of connecting bolts are different. The flat welding method can only be used for casting flanges up to 16Kg, and normal conditions are used at 10Kg or 6Kg. pipeline.

According to the professional who specializes in flange forging products, the pipe fittings are placed on the external thread of the pipe end to cover the pipe. It is used to close the pipeline and has the same function as the pipe plug. It is dustproof, waterproof, and anti-corrosive. The plasticity of the plastic itself makes the cap have strong mechanical strength, strong sealing, good chemical stability, lightweight, good heat insulation, sound insulation, shock resistance, and high specific strength.

The two sealing faces of the bolt press each other against the flange gasket and form a seal, but this also causes damage to the seal. In order to maintain the seal, it is necessary to maintain a huge bolt force, for which the bolt is made larger. Larger bolts are matched to larger nuts, which means that larger diameter bolts are needed to create the conditions for tightening the nuts.
