Stainless Steel Material of ASTM A182 F316 CLASS150 Figure 8 Spectacle Blind Flange As Per ASME B16.48
A spectacle blind flange is generally a piece of metal that is cut to fit between two pipe flanges and usually sandwiched between two gaskets. There are three types of spectacle flange: spacer fange, spade fange (paddle flange), spectacle blind flange. ... The shape of spectacle flange is like glasses.
Spectacle Blinds are simple safety devices that are installed between two pipe flanges. ... To stop the flow in the pipeline, the blind end is rotated into place between the flanges. This positively isolates the downstream piping and equipment. A Spectacle Blind is generally installed as a permanent fixture.
Flange Applications:
Water works, shipbuilding industry, petrol chemical & gas industry, power industry, valve industry,and general pipes connecting projects etc.
