Flat welding flange connection is the two pipes, pipe fittings or equipment, first fixed on a flange, between the two flanges, plus flange pad, bolted together to complete the connection. Some pipe fittings and equipment have their own flanges, which are also flange connections. Flat welded flanges are divided into threaded connection (wire connection) flanges and welded flanges. Low pressure small diameter wire flange, high pressure and low pressure large diameter are welded flange, different pressure flange thickness and connection bolt diameter and number are different. According to the different levels of pressure, large flange pads also have different materials, from low pressure asbestos pads, high pressure asbestos pads to metal pads. The flange connection is easy to use and can withstand greater pressure.
