Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Delve into the exceptional capabilities of this spiral wound gasket, meticulously crafted with a robust outer and inner ring. Engineered to perfection, an additional inner ring is adeptly incorporated to boost its performance significantly. This feature ensures impeccable gasket stability by preventing the risk of it collapsing into the pipe upon installation. It also safeguards the sealing element from extreme temperatures and harsh mediums, effectively filling the void between flanges to avert flange erosion and notably diminish failure risks. Complying with the DIN 2699 German standard, the inner rings are a requisite for all spiral wound gaskets, especially when paired with PTFE fillers as mandated by ASME B16.20 standards. They are deemed crucial for gaskets with graphite fillers as well. This particular gasket profile is optimal for both raised and flat-faced flanges. The inclusion of an external guide ring ensures precise centering on the flange face while providing remarkable radial strength that mitigates the chance of gasket blowout and serves as a compression stop. This component is typically crafted from carbon steel—either painted or zinc plated to resist corrosion—yet it can also be fashioned from alloys to withstand high temperatures and more rigorous medium applications.
