strong stress compensation, stable and reliable sealing performance
Available in a full range of styles and materials, our spiral wound gaskets are manufactured in accordance with ASME B16.20 for use in all industry flanges, including ASME/ANSI B16.5, ASME B 16.47, Series A & B. American Seal & Packing assures strict adherence to these specifications as routine inspection procedures are applied throughout the manufacturing process. In addition, we maintain trace ability of all materials used in our gasket construction to provide material certifications as required.
Normal Pressure: from 150# to 2500#
Normal Diameter: from 1/2'' to 60''
Usage: Flat and raised faced diameter flanges up to and inclusive of Class 2500.
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 flang
The standard thickness of the metallic strip is 0.2 mm.
Filler is normally used for thickness from 0.5 mm to 0.6 mm.
- Flexible graphite 98%
- Flexible graphite 99.85%
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 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.
This limitations are general and can vary according to the special customer.
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).
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.
The dimensions of the standard SWG meet the ASME, BS and EN (DIN) standards.
