Stainless Steel Flanges: Types, Specifications, Weight Chart, HSN Code, Uses & Applications

  Stainless steel flanges are essential piping components designed to connect pipes, valves, pumps and other equipment through a secure bolted joint. Their corrosion resistance, mechanical strength and availability in different configurations make them suitable for demanding industrial environments. Depending on the piping requirement, options include Weld Neck, Slip-On, Blind, Socket Weld, Threaded, Lap Joint, Long Weld Neck, Spectacle Blind and Ring Type Joint designs. A suitable Stainless Steel flange Manufacturer can provide these products according to required dimensions, pressure ratings, material grades and applicable standards. What Are Stainless Steel Flanges? A flange is a rimmed or flat component used to create a detachable connection between piping components. Unlike permanent welded joints, a flanged connection can be dismantled for inspection, cleaning or maintenance. Stainless steel construction is particularly useful where corrosion resistance and long service life...
