Flange is a discoid parts, most common in the pipeline project, the flanges are used in pairs. In the pipeline project, the flange is mainly used for pipe connection. Need to connect pipes, various install a flange, low-pressure pipe can use a wire connected flange, the use of more than 4 kg pressure welding flange. Coupled between the two flange seal point, and then bolted. Pressure flanges of different thickness and use a different bolt. The flange also known as flange or lug. Parts of the tube and the tubes connected to each other. Connected to the pipe end. Holes in the flange that can be worn bolts, so that the two flange abuts. Between the flanges with gasket seal. Flange pipe fittings refers to with a flange fittings. It can be molded by threaded connection or welded form. Flange connection consists of a pair of flange, a gasket and a number of bolts and nuts. Gasket on the two-flange sealing surface and tighten the nut on the gasket surface pressure reaches a certain value distortion, and fill the Office of the uneven surfaces of the sealing surface between the flange connection is an important connection of the pipeline construction manner
