Welding flange is used for high and low pressure large diameter

Flange is a kind of disk-shaped part, which is the most common in pipeline engineering. The flange is used in pairs and with the matching flange on the valve. In pipeline engineering, flange is mainly used for connection of pipeline. For the pipes to be connected, a flange plate shall be installed for each kind of installation. For the low-pressure pipes, the threaded flange can be used, and for the pressure above 4kg, the welding flange can be used. Add gasket between two flange plates, and then fasten them with bolts. Flanges with different pressures have different thicknesses and use different bolts.Forged Stainless Steel Weld Neck Flange is used for high pressure and low pressure big diameter. The thickness of flange plate and the diameter and quantity of connecting bolt are different under different pressure.
