Flange (also known as flange or flange) is a part of the pipe and pipe connected to each other. It is connected to the pipe end. There are holes in the flange, and bolts can be worn to make the two flanges tightly connected. Flanged pipe fittings are pipes with flanges (flanges or lands) that can be cast or threaded or welded. Flange (joint) is a pair of methods. Lan, a gasket and a plurality of bolts and nuts. The gasket is placed between the two flange sealing surfaces. After the nut is tightened, the specific pressure on the surface of the gasket reaches a certain value and then deforms, and fills the sealing surface with irregularities. At the same place, the joints are tight and leakproof. Some fittings and equipments have their own flanges, which are also flange connections. Flange connections are an important connection method for pipeline construction.
The flange connection is easy to use and can withstand large pressures. Flange connections are widely used in industrial piping. In the home, the pipe diameter is small and low pressure, and the flange connection is not visible. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.
In layman's terms, the role of the flange is to secure and seal the joint of the pipe.
