What is the definition of stainless steel flange price?Release Date: September 22, 2015
[Wenzhou Fakai Valve]:
Stainless steel flange is a disc-shaped part, which is most common in pipeline engineering. Stainless steel flanges are used in pairs and with the matching stainless steel flange on the valve. In pipeline engineering, stainless steel flanges are mainly used for pipe connection.
For the pipelines to be connected, a piece of stainless steel flange is installed. Low-pressure pipelines can use wire-connected stainless steel flanges. Welded stainless steel flanges are used for pressures above 4 kg. Add a gasket between the two stainless steel flanges and tighten with bolts. Different pressure stainless steel flanges have different thicknesses and use different bolts.
PN is the nominal pressure, which means that the unit is 0.1MPa in the international unit system and kgf / cm2 in the engineering unit system.
The determination of the nominal pressure should not only be based on the maximum working pressure, but also based on the maximum working temperature and material characteristics, not only need to meet the nominal pressure is greater than the working pressure. The stainless steel flange also has a parameter DN, which is a parameter indicating the size of the stainless steel flange.
According to the connection method, the flange connection types can be divided into: plate type flat welding flange, flat neck welding flange with neck, butt welding flange with neck, socket welding flange, threaded flange, flange cover, butt welding ring with neck Loose sleeve flanges, flat weld ring loose sleeve flanges, ring groove surface flanges and flange covers, large diameter flat flanges, large diameter high neck flanges, blind straight plates, butt weld ring loose sleeve flanges, etc.
