A spectacle blind flange is a safety device used to isolate a section of pipeline or equipment when they need to be inspected or removed from piping system. It is not like a valve, the spectacle blind flange is a permanent or long term isolation block. The spectacle blind flange is made of two pieces metal discs which are joint together by a part of steel handle. The two discs are connected by a hinge, so that the blind flange can be rotated to open or close the pipeline. Technical Specifications a. Material: Carbon steel, stainless steel, alloy steel b.
