Blind Flange – Stainless Steel ANSI/ASME
Walmi manufacture blind flange as per ANSI/ASME B16.5, which doesn’t have a bore as other kind of flanges. Blind flange always works as a seal.
Walmi typically supply blind flange with a raised face (RF), flat face (FF) or Ring Type Joint (RTJ) face. The standard raised face height is 1.6mm (1/16″) for blind flanges under 400#, 6.35mm(1/4″) for 400# and up. The raised face blind flanges have to be welded to the pipes.
Stainless steel blind flanges are often used to provide positive closer on the ends of pipes, valves, pumps or pressure vessel openings, which require easy access to the pipe inside line for inspection purpose. Stainless steel bland flanges are suited for high temperature and pressure applications, which are widely used in water conservancy, power plant, pressure vessel, oil & gas, steam and pipe fittings.
