Connection method
Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate first, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection . Some pipe fittings and equipment already have their own flanges, which are also flanged connections. Flange connection is an important connection method in pipeline construction. Flange connection is easy to use and can withstand greater pressure. In industrial piping, within the home, the pipe diameter is small, and it is low pressure, and flange connections are not visible. If in a boiler room or production site, there are flanged pipes and equipment everywhere
According to the connection method, the flange connection type can be divided into: plate flat welding flange, flat welding flange with neck, butt welding flange with neck, socket welding flange, threaded flange, flange cover, butt welding ring with neck Loose flange, flat welding ring loose flange, ring groove face flange and flange cover, large diameter flat flange, large diameter high neck flange, eight-character blind plate, butt welding ring loose flange, etc.
