Blind Flanges

Product description

Blind flange is also called blind board, and its proper name is flange cover. It is a flange without holes in the middle for sealing the pipe plug. There are many types of sealing surface, such as rise face, ring joint face, large or smalltongue face and groove face, large or small male face and female face. Blind flanges are mostly used to seal the end or opening of a pipe, which is why they come without a bore. This comes in handy for inspection and pressure tests, as it allows quick access to the pipe.
