Method of flange connection
Flange connection consists of a pair of flanges, a gasket and a number of bolts and nuts.
Flanges with holes, can wear bolts, so that the two flanges are tightly connected, between the flanges with gasket sealing. The gasket is placed between the sealing surface of two flanges. After the nut is tightened, the specific pressure on the surface of the gasket reaches a certain value and generates deformation, and fills the uneven place on the sealing surface, so that the connection is tight without leakage. Flanges are threaded connection flanges and welded flanges.
Low pressure small diameter threaded flange, high pressure and low pressure large diameter are used welding flange, flange thickness and the number of connecting bolt diameter and different pressures are different.
Flange connection is an important connection mode in pipeline construction. Flange connection is to put two pipes or equipment, first each fixed on a flange, between the two flanges, flange pad, with bolts fastening together, completed the connection. Some pipe fittings and equipment have flanged, also belong to flange connection. Flange pads are also made of different materials according to the different levels of pressure, ranging from low pressure asbestos pads, high pressure asbestos pads and tetrafluoroethylene pads to metal pads. Flange connection easy to use, can withstand greater pressure. Flange connection is characterized by easy disassembly, high strength, good sealing performance. When installing the flange, it is required that the sealing surface of the two flanges should not be damaged and should be cleaned. Gaskets used for flanges should be selected according to the design regulations.
