SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This premium spiral wound gasket is engineered with a robust outer and inner ring. An inner ring is meticulously integrated to elevate gasket performance and ensure precise alignment on the flange face with an external guide ring. This ingenious design prevents the risk of the gasket collapsing into the pipe during installation, offers superior protection to the sealing element from extreme temperatures and harsh mediums, fills voids between flanges to avert flange erosion, and significantly minimizes the likelihood of gasket failure. The inner ring, crafted from the same high-quality alloy as the winding, adheres to the stringent DIN 2699 standard (German), which mandates inner rings in all spiral wound gaskets. For gaskets with PTFE filler, the ASME B16.20 standards necessitate inner rings, while they are deemed crucial for graphite fillers. This profile is ideally suited for both raised and flat-faced flanges. The external ring provides exceptional radial strength to prevent gasket blowout and serves as a compression stop. Typically, the outer ring is constructed from carbon steel, either painted or zinc-plated to resist corrosion, though it can also be made from advanced alloys to manage higher temperatures and more rigorous medium applications.
