Large forged flange connection is to fix two pipes, pipe fittings or equipment on one flange, between the two flanges, plus flange pads, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment have their own flange, also belong to the flange connection.
Large forged flange connection is an important connection mode in pipeline construction. There are three types of sealing surface for large forged flange: flat sealing surface, which is suitable for situations with low pressure and non-toxic medium; concave and convex sealing surface, which is suitable for situations with slightly higher pressure; mortise sealing surface, which is suitable for situations with flammable, explosive, toxic medium and high pressure.
Large forged flange connection is easy to use and can withstand greater pressure. Stamping elbows of large forged flange connections are widely used in industrial pipelines. In the family, the pipe diameter is small, and is low pressure, can not see the flange connection. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.
