BL blind stainless steel RF flanges
Blind flanges are used to blank off pipelines, valves and pumps. They can also be used as an inspection cover. It is sometimes referred to as a blanking flange.
Blind Flange - A Blind flange is round plate which has all of the relevant boltholes but no centre hole, and because of this feature this flange is used to close off the ends of a piping systems and pressure vessel openings. It also permits easy access to vessels or Piping systems for inspection purposes.
