Spiral Wound Gasket

CGI Type (Gasket with Inner and outer Ring)

This type Gaskets, consist of a Gasket (Winding + Filler) with a solid metal inner and outer guide ring. A winding with an alternate combination of a STEEL strips and soft non-metallic FILLER with solid inner and outer guide ring. This type CGI is identical to CG, with the addition of an inner ring. The inner ring provides the same functions as in GI type.

CG Type (Gasket with outer Ring)

This type Gaskets, consist of a Gasket (Winding + Filler) with a solid metal outer guide ring. A winding with an alternate combination of a steel strips and soft non-metallic filler with solid outer guide ring. The outer guide ring serves to center the gasket properly in the flange joint, act as an anti- blowout device and compression gauge to prevent the spiral wound component from being crushed. Normally the outer guide rings are furnished in mild steel (Carbon steel) but can be supplied in other metal when required by operating conditions.

GI Type (Gasket with inner Ring)

This type Gaskets, consist of a Gasket (Winding + Filler) with a solid metal inner ring. A winding with an alternate combination of a STEEL strips and soft non-metallic FILLER with solid inner guide ring. The inner ring provides radial support for the gasket one the inner diameter is to help prevent the occurrences of inside buckling, collapsing and imploding. Its inner diameter is normally sized slightly larger than the inner diameter of the flange bore, minimizing turbulence avoiding uneven flow. The inner rings are normally supplied in the material as the wedding strips would component. This Gasket mostly used in valves and pumps.

R Type (Only Gasket)

This type of gasket comprises of winding with an alternate combination of a STEEL strips and a soft non-metalic FILLER. the metal strip in the gasket is performs superior resiliency and self-adjusment when compared to conventional gaskets

ONGI (Gasket with Inner Ring & Outer Nose)

This type Gasket, consist of a Gasket at (winding + filler) with Nose (Bare) outer winding a solid metal inner ring and outer bare (Nose) winding. A winding with an alternate combination of a STEEL strips and soft non-metallic filler with solid inner ring and outer nose (Base) winding. This type gaskets are mostly used in Heat exchangers where the minimum space available. The inner ring provides the same function as in GI type & CGI type. Outer Nose winding is used material same as winding metal.

ONG (Gasket with Outer Nose)

This type Gasket, consist of a Gasket at (winding + filler) with Nose (Bare) outer winding a solid metal winding as inner ring and outer bare (Nose) winding. A winding with an alternate combination of a steel strips and soft non-metallic filler with solid outer nose (Bare) winding. This type gaskets are mostly used in Heat exchangers where the minimum space available. The inner diameter of Gasket larger than the flange bore. Outer nose winding is used as some material of winding metal.
