Large Diameter National Standard Carbon Flat Welding Flange Welded Flange Plate Support To Cust
Flange connection is to fix two pipes, pipe fittings or equipment
respectively on a flange plate, and the flange pad is added between
the two flanges, which is fastened together with bolts to complete
the connection.Some pipe fittings and equipment have their own
flanges, which are also flange connections.Flange connection is an
important connection mode in pipeline construction.Flange
connection is easy to use and can withstand large pressure.Flange
connection is widely used in industrial pipelines.In the home, the
pipe diameter is small, and low pressure, no flange connection
visible.If you are in a boiler room or production site, there are
flanged pipes and equipment everywhere.
1, according to the connection flange connection type can be
divided into: plate flat welding flange, with flat welding neck
flange, butt welding neck flange, socket welding flange, threaded
flange, flange cover, with neck butt welding ring flange, ring flat
welding flange come loose, ring groove surface flange, flange
cover, large diameter plate flange, large diameter high blind
flange, butt welding neck flange, eight words ring flange, etc.
As welded iron flanges, many customers question whether the quality of welded iron flanges is better than forged welded flanges.Actually iron plate welding quality and the quality of the welding flange forging flange is the same, but the iron plate welding flange exactly what place can not be guaranteed, is also the most insecure iron plate welding flange material, because the process of general, the density of iron plate welding flange is no problem, but in the process of producing,The blank of the iron plate welding flange is rarely tested, so after the production, the material of the iron plate welding flange can not be guaranteed without testing.
