PN is the nominal pressure, indicating that the unit is 0.1MPa in the SI system of units and kgf/cm2 in the engineering system of units. Tube flange commonly used bar (kg force kgf/cm2,1bar=0.1MPa) equipment flange commonly used MPa.
The determination of nominal pressure should not only be based on the highest working pressure, but also on the highest working temperature and material characteristics, rather than just meet the nominal pressure greater than the working pressure. Another parameter of flange is DN, DN is the parameter indicating the size of flange
Jiangyin Dongsheng Flange products are widely used in petroleum, chemical, shipbuilding, construction, machinery and other industries, stainless steel flange exports to Europe, the Middle East, the United States, Japan, South Korea and other countries and regions in the world.
