JinSeal, One of the Leading Spiral Wound Gasket Manufacturers In China, Has Been Involved in SWG Gasket for over 20 Years. Metal Spiral Wound Gasket Offers High Temperature and Pressure Sealing With Good Recovery Performance, Due to These Characteristics, Gasket Sealer is Widely Used in the Applications of Extreme Temperature or High Pressure, Shock, or Vibration Due to Its Best Resistance Property when Compared with Other Gaskets Types.

JinSeal Spiral Wound Gasket 5 Types More Details as Follows: 

CGI Type Spiral Wound Gaskets Are Supplied with an External and an Internal Ring Which is Suitable for Use on Flat Face and Raised Face Flanges and Can Be Especially for High Pressure or Temperature Environments or Where Corrosive or Toxic Media Exists. the Inner Ring Gives the Gasket a Greater Resistance to Thermal Shock and Prevents the Filler Material from Being Sucked in when in the Case of Vacuum Services As Well As Gives an Additional Compression Limiting Stop and Prevents Inward Buckling Ring. Always the Inner Ring’s Material is Typically the Same As the Winding Material but Can Be Provided in Other Material Depending on the Services.

CGI Type Spiral Wound Gasket

Item No.: JAG - SW20

Spiral Wound Gasket with Inner and Outer Ring for Raised & Flat Face Flange.

For Example: SS304/SS304+FG/CS

JinSeal Provides CG Type (with Only Outer Ring). These Gaskets Are Proved to Be Suitable in Most Applications and Allow Lower Clamping Forces Than Solid Gaskets, Albeit with a Higher Cost.

The Spiral Wound Gasket Copes with an Outer Ring Made from Stainless Steel, Carbon Steel or Other Material Like Duplex, Monel or Nickel Are Always for Applications of Raised Face Flanges. the Outer Ring Works As a Center Ring That Fixes the Gasket on the Flange Faces by Providing the Blow-out Resistance of the Windings As Well As Works As a Compression Stop. the CG Spiral Wound is a Good General-purpose Gasket and is Suitable for Use with Flat Face and Raised Face Flanges.

CG Type Spiral Wound Gasket

Item No.: JSG - SW30

Swg with Only Outer Ring, for Raised / Flat Face Flange

For Example SS304/FG/CS

RIR Type Spiral Wound is a Gasket with a Solid Inner Ring That Acts As a Compression Stop and Fills the Annular Space Between Flange Bore and the Inside Diameter. It’s Designed for Use on a Heat Exchanger Where the Sealing Area is Limited. the Inner Ring’s Use Can Prevent Accumulations of Solids As Well As Reduce Turbulent Flow of Process Fluids and Minimize Erosion of Flange Faces.

RIR Type Spiral Wound Gasket

Item No.: JSG - SW40

Swg with Only Inner Ring &. Without Outer Ring, It’s Suitable for the Male and Female Flange. 

R Type Spiral Wound Gasket

Item No.: JSG10

Swg with Only Filler and Winding (sealing Element Only), Suitable for High Pressure and Temperature Applications for TG/Male/Female Flange.

For Example SS304/FG.

R-type Spiral Gaskets Are the Basic Style, Its Inner and Outer Diameter Requires a Minimum of Three Plies and a Maximum of Five Plies of Preformed Stainless Steel Strip Without Filler, Which Provides Greater Stability and Better Compression Characteristics. the Outer Windings Shall Be Spot Welded Circumferentially with a Minimum of Three Welds or a Maximum Space Between Spot Welds of 76mm when the Gasket’s Dimension Increases

H Type Spiral Wound Gasket

Item No.: JSG - SWH

Spiral Wound Gasket for Heat Exchanger.

For Example SS304/FG with 1 Bar of Double Jacketed.

H Type Spiral Wound Gasket is a Kind of Heat Exchanger Spiral Wound Gasket Which is Created for Heat Exchangers, It’s the Same with Common Spiral Wound Gaskets in Structural Type Except That Barrettes(bar) Are Required and the Bars/ribs Are Securely Fastened to the Id of the Gasket. Always the Barrettes Are Always Double Jacketed Type or Kammprofile Type in the Same Material of Windings and Fillers. H-type Spiral Wounds Can Also Be Equipped with an External Ring and an Internal Ring to Provide Better Stability but Kindly Refer to JinSeal Technical Team for the Use of Applications.

How to Choose Filler

The Important Part is the Sealing Element (also Called Filler) Made Up of V-formed Ss Strip and Non-metallic Filling Tape, the Material Can Be Changed According to Different Chemical Compatibility Requirements. Graphite Filler Strip is Good to Be Used in a High-temperature Environment, PTFE Filling Strip is for Acids and Other Corrosive Mediums Non-asbestos’ Use is Increased when the Health Problems with Asbestos Became Known. but It’s Only Recommended for Low Temperature Less Severe Applications Due to the Rubber Content. Ceramic is in Extremely High-temperature Applications. the Filler is Not So Common As It Cannot Achieve the Same Leak Tightness As Graphite
