Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing the remarkable James Walker Spiral Gasket with PTFE Filler and SS347 Material, a marvel of engineering designed to ensure superior performance and durability. This spiral wound gasket features a robust solid outer and inner ring, with an additional inner ring ingeniously inserted to enhance gasket performance. The innovative external guide ring ensures precise centering on the flange face, offering unmatched reliability during installation. The inclusion of the inner ring is a game-changer, preventing gasket implosion into the pipe, safeguarding the sealing element from extreme environments, filling voids between flanges, and minimizing the risk of failure. Crafted typically from the same alloy as the winding, the inner ring adheres to the stringent DIN 2699 standard of Germany, mandating its presence in all spiral wound gaskets. For PTFE fillers, the ASME B16.20 standards confirm its necessity, and it is deemed essential for graphite fillers as well. This gasket profile is the perfect fit for raised and flat-faced flanges, with the external ring providing additional radial strength to avert blowouts, serving as a reliable compression stop. While carbon steel, either painted or zinc-plated, is commonly used for the outer ring to prevent corrosion, specialized alloys are available for higher temperature and more demanding applications.
