The connection of cast flanged pipe fittings is to fix two pipes, pipe fittings or devices on the flanged pipe fitting plate respectively. The connection is made by tightening the two flanged fitting plates, flange gaskets and bolts together. Some fittings and devices used to have their own flanges, which is also how flanged fittings are connected.

Flange pipe connection is an important connection method in pipeline construction. Flanged pipe fittings are used in building valves that interrupt the cathode maintenance, transmission and distribution network and buried pipe valve wells that need to be interrupted by potential segments (areas). Forged flanged pipe fittings are easy to use and can withstand high pressure. Carbon steel flange connections usually use bolted connections, which are closed in two surrounding planes at the same time, but this connection is only part of the equipment.

For example, if the cast flanged pipe fittings are connected with the water pump, it is not good to call the water pump "flanged pipe fittings parts". Assuming that in the boiler room or production site, there are pipes and devices connected by flanged pipe fittings everywhere. Low pressure small diameter wire connection method flanged pipe fittings, high pressure and low pressure large diameters are all welded and cast flanged pipe fittings.

The thickness of flanged pipe fittings with different pressures, the diameter and number of connecting bolts are different flat welding methods. Cast flange pipe fittings can only use up to 16kg, and generally use 10kg or 6kg pipes. According to those who specialize in casting products of flanged pipe fittings, the pipe fittings are installed on the external thread of the pipe end to cover the pipe. It is used to close the pipeline, and has the same effect as the pipe plug, and has the functions of dustproof, waterproof and anti-corrosion. The plasticity of the plastic itself makes the cap have strong mechanical strength acceptance ability, strong sealing, good chemical stability, light weight, heat insulation, sound insulation, impact resistance and high specific strength.

The two sealing surfaces of the bolt press each other against the flange gasket to form a seal, but this also damages the seal. In order to maintain the seal, a huge bolt effect force needs to be maintained, and for this, the bolt needs to be made larger. A larger bolt needs to mate with a larger nut, which means a larger diameter bolt is needed to allow for the tightening of the nut.
