Technical Benefits: >Metallic winding suited for cyclic loading
                                     >Outer ring center gasket
                                     >Inner/outer ring provides additional blow-out strength
                                     >Inner/outer ring provides a compression stop
                                     >Prevents flange erosion
                                     >Prevents inward buckling
                                     >Reduces turbulent flow
                                     >Recommended for high pressure/temperature applications
Applicable Standards: >ASME B16.20
                                           >BS, JIS,DIN
                                           >Suited for ASME B16.47 series A/B flanges
Construction

Metallic Strip
The standard thickness of the metallic strip is 0.2 mm.

Filler
Filler is normally used for thickness from  0.5 mm to 0.6 mm.
- Flexible graphite 98%
- Flexible graphite 99.85%
- PTFE
- Ceramic
- Asbestos

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 avoid excessive 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 srtip.

Thickness

The standard manufacturing thickness for spiral wound gaskets are: 3.2 mm; 4.5 mm; 6.5 mm (measured across metallic strip not including the filler, which protrudes slightly beyond the metal).

Manufacturing tolerances
The tolerance of the gasket diameters (d1, d2, d3, d4, s, s1) are stipulated by ASME B 16.20 and  DIN 2632-2638 standards. The gaskets designed for non-standard flanges meet the recommendations by the ASME B 16.20.

Dimensions
The dimensions of the standard SWG meet the ASME, BS and EN (DIN) standards.
