304H
are widely used in low pressure piping systems, as no welding is involved while connecting the flanges to pipes or other equipment. However, the flange may be welded around the joint after assembly, but it is not considered a satisfactory method of increasing its applications. Grade 304H Threaded flanges are also known as 304H ss screwed flanges and are similar to ss 304H slip-on flanges, but the bore is threaded to enable assembling without welding. Stainless Steel 304H pipe flanges are usually used with pipes that have external threads.
We offer wide range of ASME B16.48 F304 Weld Neck Flanges, ANSI B16.5 304H Socket Weld Flanges, 304L Stainless Steel Blind Flanges, SS 304H Orifice Flanges, SS 304 Spectacle Blind Flanges, B16.47 F304L Screwed / Threaded Flanges, ASME B16.48 F304L Reducing Flanges, EN 1092-1 SS 304H Ring Type Joint Flanges (RTJ) etc.
