  • What is a Spectacle Blind Flange: Spectacle blind flange (spectacle flange) is also called figure-8 blind flange, it is made of two pieces metal discs which are joint together by a part of steel handle. It is not like a valve, the spectacle blind flange is a permanent or long term isolation block.
  • Parts of the Spectacle Blind Flange: One piece disc of the spectacle flange is a blind without any hole on it, is could block the flow fluid when working, another piece disc is a blind which have an opening to allow the fluid run through the pipe when working. The spectacle blind flange shape is like a pair of glasses, so it is also called glasses flange. The spectacle flange can be rotated to place either the blind or hollow end within a piping system, thereby the system could be opening or closing.
  • Sealing Face of Spectacle Blind Flanges: The spectacle flange face should be same with the pipe flanges, it could be raised face (RF), flat face(FF) or ring type joint face (RTJ). The face dimensions should have same specification with the pipe flanges.
