  Stainless Steel Flange is mainly used in food industry and surgical equipment, adding molybdenum to obtain a special structure for corrosion resistance. Because of its better chloride corrosion resistance than 304, it is also used as "marine steel". SS316 is usually used for nuclear fuel recovery. Grade 18/10 Stainless Steel Flange usually also meets this application level.

  In order to save stainless steel, the welding ring is adopted. The structure must be machined after the welding ring and nozzle are welded. The general use is below the operating pressure of 2.5MPa. Smooth surface 1/2" ANSI B16.5 Stainless Steel Flange are not suitable for toxic and flammable and explosive materials with high gas tightness because of their poor connection rigidity and poor sealing performance.

  The connection plate of this structure is made of carbon steel or stainless steel. If carbon steel is used, the surface needs to be plated with nickel. The sealing roughness of the cast aluminum ZL7. connection plate is 20, and there is no obvious radial groove and mark.
