Some fittings and equipment have their own flanges, which are also flanged connections.

Flat welding flange threaded connection (wire connection) flange and welded flange. Low pressure small diameter wire flange, high pressure and low pressure large diameter are welded flange, thickness of flange and bolt of different pressure The diameter and quantity are different. According to the different grades of pressure, the flange pad also has different materials, from low pressure asbestos pad, high pressure asbestos pad to metal pad. Flange connection is convenient to use and can withstand large pressure. In industrial pipeline In the home, the flat welding flange connection is widely used. In the home, the pipe diameter is small, and it is low pressure, and the flange connection is not visible. If it is in a boiler room or production site, flanged pipes and equipment are everywhere.
