Carbon steel Spectacle Blind Flanges

Carbon steel spectacle blind flange is also known as figure-8 blind flanges. They are generally made of pieces of metal. Spectacle blind flange cut to fit between two pipe flanges and usually sandwiched between two gaskets. A spectacle blind flange raised face is often made from two metal discs that are attached to each other by a small section of steel.

The shape of spectacle blind flange is similar to a pair of glasses or “spectacles” hence the name spectacle blind. One end of the blind will have an opening to allow flow through the pipe during operation and the other end of stainless steel spectacle blind flange is solid to block flow during maintenance.

The whole idea of a spectacle blind flange ASME b16.48 is so that one can be absolutely sure that an item of equipment is properly and securely blanked off with no possibility of leakage through a valve at the time of maintenance. It is possible to divert the flow to other items of equipment but not just bypassed around the blank as this would compromise the safety function of the spectacle blind.

A flat face 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 flange, spade flange paddle flange, spectacle blind flange. At DINESH INDUSTRIES, Spectacle Blind Flanges Manufacturer In India, a spectacle blind flange is a combination of a spade flange and a spacer flange.

The shape of piping spectacle blind flange is like glasses. After replacing the gaskets, the bolts can be re-assembled and tightened. It is necessary that the pipeline should be valve off and pressure relieved before loosening the flange bolts. If you want to prevent unnecessary weight to a flange connections, designer usually will choose the separated two parts spacer flange and spade flange instead of the raised face spectacle blind flange.
