SPIRAL WOUND GASKET
COMPELLING DESCRIPTION:
Exceptional Product Type:XINSEN-SD
Remarkable Features:
This meticulously engineered spiral wound gasket, featuring robust outer and inner rings, includes an additional inner ring to significantly enhance performance. The external guide ring ensures precise centering on the flange face. This inner ring is integral, preventing the gasket from collapsing into the pipe during installation and shielding the sealing element from extreme temperatures and harsh mediums. It also fills the void between flanges to counteract erosion and mitigate the risk of failure. Typically, the inner ring mirrors the alloy composition of the winding. The German DIN 2699 standard mandates inner rings in all spiral wound gaskets, and ASME B16.20 standards require them for gaskets with PTFE filler, deeming them crucial for graphite fillers as well. This profile is predominantly employed in both raised and flat-faced flanges. The external ring adds valuable radial strength to avert gasket blowout and functions as a compression stop. Commonly, this profile is used in both raised and flat-faced flanges. The outer ring is often crafted from carbon steel, either painted or zinc-plated to guard against corrosion, though it can also be made from alloys suitable for higher temperatures and more challenging medium applications.
