Spiral Wound Gaskets in Dubai

Spiral Wound Gaskets in Dubai

A spiral-wound gasket is made of alternate plies of V-preformed metal strip and soft filler that are tightly and spirally wound together. According to the need of the mating flange, the gasket is provided with an outer ring, an inner ring or both outer and inner rings. The outer ring serves as a compression stop, anti-blowout device, which properly centers the gasket on the flange. The inner ring acts as a compression stop and is used to fill the annular space between the flange bore and the gasket inside diameter to minimize turbulence of process fluids and erosion of flange faces.

 

Advantages 

Sealing under heavy operating conditions

Strong stress compensation, stable and reliable sealing performance even under frequent pressure fluctuation condition

Solid construction provides stability and saleability even when the sealing surfaces are slightly corroded or bent

Easy installation

Flexible graphite 98%

Flexible graphite 99.85%

PTFE

Ceramic, Micalit

 

Centering ring :

The centering ring does not come into direct contact with contained fluid. It is normally made of carbon steel and electro plated or painted to avoid corrosion. Other materials are available on request.

Inner ring:

Inner ring is used to avoidexcessive compression due to high seating stress in high-pressure service and it is also used to reduce turbulence in the flange area. It is normally made of the same material as the gasket metallic strip

Ring Materials:

Carbon Steel

SS 304, SS316, SS321

Monel, Inconnel , Duplex etc...
