How to choose stainless steel flange material? The material of the connection disk of this structure is carbon steel or stainless steel. If carbon steel is used, the surface needs to be nickel-plated and the clamp material is cast aluminum ZL7. The sealing roughness of the connection disk is 20 and there must be no obvious radial groove And scoring.

It is mainly used in the food industry and surgical equipment. The addition of molybdenum makes it obtain a special structure resistant to corrosion. Because it has better resistance to chloride corrosion than 304, it is also used as "marine steel". SS316 is usually used in nuclear fuel recovery equipment. 18/10 grade stainless steel usually also meets this application level.

In order to save stainless steel materials, a welding ring is used. This structure must be processed after the welding ring and the tube have been welded. Generally used hanging below 2.5MPa operating pressure. Smooth-face flat welding flanges are not suitable for equipment with high air tightness requirements for toxic and flammable and explosive media due to poor connection rigidity and poor sealing performance.
