Flange wholesale Changsha flange price purchase first choice Gerunde Pipe Industry

- .Flange (<) is also called flange or flange. Flange is a part that connects pipes to each other and is connected to the pipe end. There are bolt holes on the flange, and the bolts tightly connect the two flanges. The flanges are usually sealed with gaskets (flange gaskets).

Most gaskets are cut from non-metallic plates or made to specified sizes by professional factories. The materials are asbestos rubber plates, asbestos plates, polyethylene plates, etc. There are also metal-clad gaskets made by wrapping non-metallic materials such as asbestos with thin metal plates (tinplate, stainless steel), and a wound gasket made of thin steel strips and asbestos strips.
