DN15-DN600 stainless steel blind flange blanking flange

DN15-DN600 stainless steel blind flange , blanking flange is a solid, circular plate used to seal off the end of a piping system or a pressure vessel opening. Different from the standard Flanges that allow fluid or gas to pass through, a Blind Flange has no central bore and completely blocks the pipeline.

Key Features of the blind flange, blanking flange:

1. Bolted Connection: They are bolted to a matching flange rather than permanently welded shut, allowing easy access for internal inspections or cleaning.

2. Gasket Use: Like regular flanges, they are paired with a gasket (often a solid, ring, or full-face gasket) between the mating surfaces to ensure a leak-proof seal.

3. Face Types: They are available in various face designs to match the connected pipe, most commonly Raised Face (RF), Flat Face (FF), or Ring Type Joint (RTJ).

4. Material: DN15-DN600 stainless steel blind flange , blanking flange is made from stainless steel, 304/304L & 316/316L Stainless Steel Available.
