SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This exceptional spiral wound gasket features a robust outer and inner ring design. The inner ring is meticulously inserted to enhance the gasket's performance while an external guide ring ensures precise centering on the flange face. The inner ring also serves multiple crucial functions: preventing the gasket from collapsing into the pipe during installation, safeguarding the sealing element from extreme temperatures and harsh media, filling the flange void to prevent erosion, and reducing the risk of failure. Typically made from the same high-grade alloy as the winding, the inner ring adheres to DIN 2699 (German) standards, which mandate inner rings in all spiral wound gaskets. For gaskets with PTFE filler, inner rings are essential as per ASME B16.20 standards and are highly recommended for graphite fillers. This versatile profile is predominantly used in raised and flat-faced flanges. The external ring adds extra radial strength to prevent blowouts and serves as a compression stop. Often crafted from carbon steel—either painted or zinc-plated for corrosion resistance—it can also be made from specialized alloys to suit higher-temperature and more severe media applications.
