Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the exceptional craftsmanship of our spiral wound gasket, meticulously designed with a robust solid outer and inner ring. The enhancement of an inner ring is not just a feature; it's a revolution in gasket performance, ensuring optimal centering on the flange face with the precision of an external guide ring. This vital addition mitigates the risk of the gasket collapsing into the pipe during installation, safeguarding the sealing element against extreme temperatures and aggressive media. It also fills the void between flanges, thwarting erosion and significantly reducing potential failure risks. Mirroring the winding alloy, the inner ring adheres to the stringent DIN 2699 standards, a German benchmark, and is imperative for gaskets featuring PTFE fillers as per ASME B16.20 standards, with particular importance for graphite fillers. Ideally suited for both raised and flat-faced flanges, the external ring offers unparalleled radial strength to prevent blowouts, doubling as a compression stop. Typically crafted from carbon steel and treated with paint or zinc plating to resist corrosion, the outer ring is also available in alloys for high-temperature and severe media applications.
