SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This exceptional spiral wound gasket boasts a robust design with both solid outer and inner rings. The inclusion of an inner ring significantly boosts its performance, ensuring precise centering on the flange face thanks to an external guiding ring. The inner ring's primary role is to prevent implosion into the pipe during installation, protect the sealing element from extreme conditions, and fill any voids between flanges to safeguard against erosion, thereby enhancing longevity and reliability. Crafted usually from the same alloy as the winding, the inner ring adheres to the DIN 2699 standard, requiring its presence in all spiral wound gaskets. For gaskets featuring PTFE filler, ASME B16.20 standards mandate inner rings, and they are highly recommended for those with graphite fillers. This versatile profile is ideally suited for both raised and flat faced flanges. Additionally, the outer ring affords extra radial strength to avert any blowout and serves as a compression limiter. Commonly made from carbon steel with an anti-corrosion finish or tailored from alloys for high-temperature and severe application needs, this component epitomizes durability and efficiency.
