SPECTACLE FLANGES

What is a spectacle flange?

• Made from single metal piece, these

flanges are cut into two discs: one is a

solid plate while the other is a ring.

• The two discs pieces are joined

together with a section of steel similar

to that of the nose piece of a pair of

glasses.

• Hence, the name ‘spectacle flanges’.

They are also called as ‘figure8’ flanges.

Uses of Spectacle flanges

• The main purpose of this flange

is to prevent any kind of leakage

during the maintenance period

of pipes.

• Spectacle flanges are pressure

retaining plates used in high

pressure piping networks.

• When a piping system is under

inspection, cleaning or maintenance

process, the blind end of the

spectacle flange blocks the flow of

the inner fluid in the pipe.

• On the other hand, the open end (or

the ring) permits flow of the inner

fluid during operation period of the

piping system.

• In short, the spectacle flange can

be easily rotated to open and

close the flow from pipes.

• They are permanently installed

on pipes and installations that

require separate regularly for

various maintenance purposes.

Merits

• These flanges do not require

welding

• They have high pressure

tolerance.
