Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the extraordinary features of our Graphite Metal Gasket, meticulously crafted with a spiral design and strengthened with a robust SS347 outer ring. This gasket is engineered with a solid outer and inner ring, with an additional inner ring thoughtfully inserted to significantly boost overall gasket performance. The external guide ring ensures precise centering on the flange face, minimizing the risk of gasket implosion during installation. This inner ring safeguards the sealing element from extreme conditions and mediums, fills the void between flanges to prevent erosion, and markedly reduces the likelihood of failure. Typically crafted from the same alloy as the winding, the inner ring adheres to the stringent DIN 2699 standards (German), which mandates inner rings in all spiral wound gaskets. ASME B16.20 standards require inner rings for gaskets with PTFE fillers, emphasizing their importance for graphite fillers as well. This gasket profile is expertly designed for use in raised and flat-faced flanges. The outer ring, made of durable carbon steel (often painted or zinc-plated to resist corrosion), can also be fashioned from high-grade alloys for applications involving higher temperatures and more severe environments. It provides additional radial strength to counteract gasket blowouts and functions as a reliable compression stop.
