Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing the pinnacle of gasket engineering: our spiral wound gasket, crafted to meet the most demanding industrial standards. This innovative gasket boasts a robust outer and inner ring design. The strategically inserted inner ring significantly boosts performance by securely centering the gasket on the flange face. Designed to prevent gasket implosion during installation, the inner ring offers a protective shield against extreme temperatures and harsh media. It effectively fills the void between flanges, safeguarding them from erosion and minimizing the risk of failure. Typically crafted from the same alloy as the winding, the inner ring complies with the rigorous DIN 2699 standard (German) and is essential for gaskets with PTFE filler under ASME B16.20 standards, and strongly encouraged for those with graphite fillers. Optimally suited for both raised and flat-faced flanges, the gasket's external ring adds superior radial strength, averting blowouts and serving as a reliable compression stop. Commonly made from carbon steel with protective coatings or durable alloys, this outer ring is designed for high-temperature and severe media applications, ensuring lasting resilience and performance.
