SPIRAL WOUND GASKETS
Spiral Wound gaskets are available in a variety of styles to suit the particular flange facing being utilized on the flanges.
Style W
A winding is made of alternate plies of a metal wire and soft non-metallic filler. The metal wire in the gasket is preformed into a “chevron” configuration, allowing superior resiliency and self-adjustment when compared to conventional gaskets. The Style W is just a sealing component (winding) only, which is normally used on tongue and groove joints, male and female facings and groove to flat flange facings.
Style RW
Style RW gaskets consist of a winding with a solid metal outer guide ring. These gaskets can be used on plain flat face flanges and on raised face flanges. The outer guide ring serves to center the gasket properly in the flange joint, acts as an anti-blowout device, provides radial support for the Spiral Wound components, and acts as a compression gauge to prevent the Spiral Wound component from being crushed.
Normally the outer guide rings are furnished in mild steel, but can be supplied in other metal when required by operating conditions.

Spiral winding only (Sealing Element)
Style RWI
Style RWI is identical to style RW, with the addition of an inner ring. The inner ring also serves several functions. Primarily, it provides radial support for the gasket on the I.D. to help prevent the occurrences of buckling or imploding. Its I.D. is normally sized slightly larger than the I.D. of the flange bore, minimizing turbulence in process flow. The inner rings are normally supplied in the same material as the spiral wound
component. Brouz Arabian Factory normally manufactures standard Style RW and RWI spiral wound gaskets to ASME B16.20, designed to suit ASME B16.5 and ASME B16.47 flanges.
Style WI
Style WI gaskets consist of a winding with a solid metal Inner ring. Inner ring acts as a compression stop,
fills the annular space between flange bore and the inside diameter of the gasket .Designed to prevent
accumulation of solid ,reduce turbulent flow of process fluids and minimize erosion at flange faces .suitable
for male and female pipe flanges.
