Product Description

Revolutionary SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Outstanding Features:
This advanced spiral wound gasket boasts a robust solid outer and inner ring design. The ingenious inclusion of an inner ring significantly enhances gasket performance while the external guide ring ensures precise centering on the flange face. This inner ring is meticulously engineered to prevent the gasket from collapsing into the pipe upon installation. It safeguards the sealing element from intense temperatures and harsh mediums, filling the void between flanges to avert flange erosion, and minimizing the risk of failure. Crafted from the same high-quality alloy as the winding, this inner ring is specified by the DIN 2699 standard (German) for all spiral wound gaskets. According to ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and are highly recommended for those with graphite fillers. This sophisticated profile is ideally suited for use in both raised and flat-faced flanges. The external ring delivers unparalleled radial strength to thwart gasket blowout and serves as an effective compression stop. Typically fabricated from carbon steel, which is either painted or zinc-plated to resist corrosion, the outer ring can also be made from various alloys to cater to high-temperature and severe medium applications.
