Tongue and groove stainless steel flange 

Tongue And Groove Face Flanges The connection between the flat welding flange and the pipe is to insert the pipe into the appropriate position of the hole flange, and then weld the lap joint. Like the concave-convex flange, the tongue-and-groove flange gasket will not be extruded in the groove, the pressing area is the smallest (only 52-68% of the flat flange and the concave-convex flange), and the gasket is evenly stressed. Since the gasket is not in direct contact with the medium, the corrosion of the medium and the penetration of the pressure mechanism are minimal, and it can be used in occasions with strict sealing requirements such as high pressure, flammable, explosive, and toxic media. This kind of sealing surface gasket has good neutrality during installation, and it is difficult to process the sealing surface and replace the gasket.       Material  …
