The temperature limitation of the gasket is dictated by the combination of metallic and non-metallic materials used in its construction. Gasket widths as narrow as 5/16 (8mm) can be manufactured dependent on diameter. Very large gasket diameters can also be produced. Nominal gasket thick- ness is Gasket Tolerances:Cutting & ThicknessGenerally, RAM quotes gaskets at a tolerance of ± 0.5mm. This can seem to some designers/engineers a large margin of error. Below we discuss why this is the case and what can be done when tolerances are critical. How a rubber gasket is creating a seal. To work a gasket must be softer than the flanges and distorted by them. Inner Rings Required - GarlockNov 11, 2013 · dimensions as well as the required markings on the gaskets. You may encounter hybrid metal gaskets in the industry that are a cross between a spiral wound and kammprofile gasket. One such design is a thick, extruded wire that is spiral wound and welded to look like a kammprofile. However, products, such as this, are NOT ASME B16.20 compliant.
The Design/dimensions of the gasket diameters are stipulated by the ASME B16.20 * Due to the continuous development of our products, design or construction may change without prior notice. Specification:The Spiral Wound Gasket with center Ring is for use w ith flat face and raised face flanges, this gasket features increased compressive SPIRAL WOUND GASKETS - Flexitallic USAinvented the spiral wound gasket in 1912. SPIRAL WOUND GASKETS First and Foremost The concept of spiral wound gasket construction was originated by Flexitallic in 1912, starting a new era in safe, effective sealing. The primary purpose for this development was the increasingly severe temperatures and pressures used SPIRAL WOUND GASKETS DIMENSION TO ASME B16.20 4) Tolerance is ± 0.76 mm. 5) these gasket dimensionare not suitablefor use with slip-on screwed flanges, in this case consult themanufacturer. = For information only FOR CONTRACTING & TRADING LTD.

Tolerance in the Dimension of the Spiral Gasket Thickness tolerance is ±0.13 mm measured across the metallic portion of the gasket, not including the filler, which may protrude slightly beyond the metal. Outside diameter tolerance for NPS 12 through NPS 8 is ±0.8 mm; for NPS 10 through NPS Spiral Wound Gaskets - MSO IndustriesXR Gaskets Tolerance Table (Gasket with container outer ring) Size I.D.
