The flange is sealed with gasket. Flange threaded connection (thread connection) flange, welding flange and clamp flange. The flanges are used in pairs, and the low pressure pipe can be used with wire flanges, and the welding flange is used for more than four kilograms of pressure. Between two flanges, add a gasket and tighten the bolt. The flange thickness of different pressure is different, and the bolts they use are different.
Flanges, or flanged flanges or flanges. The flange is the part of the pipe that is connected to the pipe and is used for the connection between the end of the pipe. Also useful for the flange of the equipment import and export, for the connection between two devices, such as reducer flanges.
