CG Type Spiral Wound Gasket with Outer Ring

spiral wound gasket

A spiral wound gasket is manufactured by spirally winding a preformed metal strip and a filler on the outer periphery of metal winding

mandrels. The winding mandrel outside diameter forms the inner diameter of the gasket and the superposed metal and non-metallic

windings are continually wound until the required outer diameter is attained.

 

Spiral wound gasket with outer ring with suitable dimensioning of the centering ring, the sealing element is accurately centered on

the flange face by the bolts. A general purpose gasket for use with flat face and raised face flanges

Basic Type - R

Basic construction type, inner and outer diameters are reinforced with several piles of metal without filler

to give greater stability and better compression characteristics. Suitable for tongue and groove, male and

female or grooved to flat face flange assemblies.

Inner Ring Type - IR

Solid inner metal ring acts as a compression stopper. To prevent accumulation of solids, reduce turbulent flow

of process fluids and minimize erosion. Damages of gasket between flange bore and the inside diameter, the

annular space is filled up by solid inner metal ring. Suitable for male and female pipe flanges.

Outer Ring Type - CG

Solid inner metal ring acts as a compression stopper. To prevent accumulation of solids, reduce turbulent flow

of process fluids and minimize erosion. Damages of gasket between flange bore and the inside diameter, the

annular space is filled up by solid inner metal ring. Suitable for male and female pipe flanges

Inner and Outer Ring Type - CGI

A inner ring & outer ring type gasket will give an additional compression limiting stopper for gasket inner and outer

side. It will prevent the corrosion on flange faces at annular space. Suitable for used with flat face and raised face

flanges and specified for high pressure temperature service class 900 and above or other situations

 

Specifications:

Products are manufactured in accordance with all relevant gasket standards to suit flange designations: ASME B 16.20, MSS SP-44, API 605,

DIN 2632-2638 DIN EN1514-2, JIS B2404, BS EN1514-2 , etc. Or products can be customized according to the users’ requirements

(no-standard spiral wound gasket). Please provide the specific drawings if the gasket is no-standard.

 

Main Applications

Pipe, valve, pump, thermal exchange, condensing tower, plain hole and man hole of flange, etc. Petrochemical, chemical, mechanical

manufacturer, power station, metallurgy, shipbuilding, medical and pharmaceutical unclear power station and navigatio

 

Advantages for spiral wound gasket:

• Combinations of metal strip and filler are selected to suit the specific fluid media and operating conditions.

• Make gaskets suitable for high pipeline pressure on flat or raised flange faces.

• Gasket are made in a wide variety of sizes and shapes.

• Temperatures from cryogenic up to 1000 °C

• High and low temperature resistance

• Quick to install and remove

 

Package:

Spiral wound gasket: packaged with plastic film, and in wooden pallets or cases.

Shipping:

Spiral wound gasket: by sea, by train or by air.
