How to choose the material of stainless steel slip on flange

　　It 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. stainless steel 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 ASTM A105 PN16 Stainless Steel Slip On 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 joint 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, and the seal roughness of the cast aluminum . And there is no obvious radial groove and mark.
