Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the robust engineering of our spiral wound gasket, masterfully crafted with a solid outer and inner ring for unparalleled performance. Designed with precision, an inserted inner ring significantly boosts the gasket's performance by ensuring accurate centering on the flange face. This innovative inner ring is crucial in preventing the gasket from imploding into the pipe during installation, safeguarding the sealing element against extreme temperatures, and resisting aggressive mediums. It fills the flange gap to prevent erosion and minimizes the risk of failure. Constructed typically from the same alloy as the winding, the inner ring's inclusion is mandated by the DIN 2699 standard for all spiral wound gaskets and is essential for PTFE fillers under ASME B16.20 standards, as well as highly recommended for graphite fillers. This versatile profile suits both raised and flat-faced flanges. Meanwhile, the external guide ring bolsters radial strength, averting gasket blowout and serving as a dependable compression stop. Our outer rings are generally forged from carbon steel, expertly painted or zinc-plated to resist corrosion, and are available in specialized alloys for high-temperature and severe medium applications.
