What is a Blind flange?

Blind Flange

Stainless Steel Blind Flange, also known as a blind disk or flanged pipe plug, is similar to a flange cover. To seal the pipe entrance, a blind flange has no openings in the middle. As a result, it serves the same purpose as a pipe stopper or a pipe cap. The distinction is that a blind flange is a removable piece of equipment that is simple to repair or maintain. Sanjay Metal India is a leading ANSI B16.5 BLRF Flanges Stockist and Supplier in India.
