Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This exceptional spiral wound gasket boasts a robust outer and inner ring structure. The inclusion of an inner ring significantly elevates the gasket's performance by providing enhanced security and stability. It is meticulously engineered with an external guide ring for precise centering on the flange face. The inner ring is crucial; it safeguards against potential implosion into the pipe during installation, shields the sealing element from extreme conditions, fills voids to prevent flange erosion, and minimizes failure risks. Typically, the inner ring matches the winding's alloy, adhering to the DIN 2699 standard which mandates inner rings for all spiral wound gaskets. ASME B16.20 standards require inner rings for gaskets with PTFE filler and highlight their importance for graphite fillers as well. Designed for raised and flat-faced flanges, the outer ring offers additional radial strength to combat blowout and serves as a vital compression limiter. Often crafted from carbon steel with corrosion-resistant paint or zinc plating, the outer ring can also be made from specialized alloys for optimal performance in high-temperature and severe environments.
