Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the exceptional performance of our spiral wound gasket, designed with a robust outer and inner ring. This innovative gasket is meticulously crafted with an added inner ring to significantly enhance its performance. The external guide ring ensures precise centering on the flange face, making installation seamless. The inclusion of the inner ring mitigates the risk of the gasket collapsing into the pipe during installation, ensuring optimal protection of the sealing element from harsh temperatures and elements. It also effectively fills any voids between flanges, preventing erosion and drastically reducing the possibility of failure. Made typically from the same alloy as the winding, the inner ring is crucial for gaskets with PTFE filler according to ASME B16.20 standards, and is highly recommended for graphite fillers, adhering to DIN 2699 standards. This gasket profile excels in both raised and flat-faced flanges, providing unparalleled radial strength to withstand high pressures and prevent blowouts. The outer ring, often composed of carbon steel and treated to resist corrosion, can be crafted from stronger alloys for use in high-temperature and demanding conditions.
