Flexitallic range of spiral wound gasket products manufactured in accordance with ASME B16.20 are available for immediate delivery.
Some of the basic styles available are the Style R, Style RIR, Style CG and the Style CGI. The Style R is in accordance with the requirements of BS 7531 grade X. The basic construction type and inner and outer diameters are reinforced with several plies of metal without filler to give greater stability and better compression characteristics. These are suitable for tongue and groove or male and female or grooved to flat face flange assemblies.
The style RIR has a solid inner metal ring that acts as a compression stop and fills the annular space between flange bore and the inside diameter. This is designed to prevent accumulation of solids, reduce turbulent flow of process fluids and minimise erosion of flange faces. They are suitable for male and female flanges.
The CG style utilises an external ring which accurately centres gasket on flange face; provides additional radial strength to prevent gasket blow-out and acts as a compression stop. A general purpose gasket suitable for use with flat face and raised face flanges. Class 900 and above an internal ring is recommended.
A style CG gasket fitted with internal ring which gives an additional compression limiting stop and provides heat and corrosion barrier protecting gasket windings and preventing flange erosion. Suitable for use with flat face flanges and specified for high pressure/temperature service - class 900 and above or where corrosive or toxic media are present.
In addition to spiral wound gaskets, we are available to supply, ring type joints, kammprofiles and metal-jacketed gaskets.
