The role of flanges in pipelines

　　Stainless steel flanges are a type of disc-shaped component that is most common in pipeline processes, and flanges are used in pairs.

　　In pipeline engineering, flanges are mainly used for connecting pipelines. Install a flange plate in various pipelines that need to be connected. Low pressure pipelines can use threaded flanges, and welding flanges can be used for pressures above 4 kilograms. Add sealing points between the two flange plates and tighten them with bolts. Flanges with different pressures have different thicknesses and use different bolts.

　　When connecting water pumps and valves to pipelines, the local parts of these equipment are also made into corresponding flange shapes, also known as flange connections. Any connecting part that is bolted together and closed at the periphery of two planes is generally referred to as a "flange", such as the connection of a ventilation duct. This type of part can be referred to as a "flange type part". But this connection is only a partial part of the equipment, such as the connection between stainless steel flanges and water pumps, so it is not easy to refer to water pumps as "flange type parts". Smaller parts such as valves can be called "flange parts".
