SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This advanced spiral wound gasket is designed with a robust solid outer and inner ring for optimal performance. For enhanced durability and effectiveness, an inner ring is meticulously inserted to boost gasket performance, ensuring precise centering on the flange face with an external guide ring. The inner ring's role is pivotal: it safeguards against the gasket collapsing into the pipe during installation, shields the sealing element from extreme environmental conditions, and fills the flange void to avert erosion, thereby significantly reducing any potential failure. Typically, the inner ring is crafted from the same alloy as the winding for consistency and reliability. The prestigious DIN 2699 standard mandates inner rings for all spiral wound gaskets, aligning with ASME B16.20 standards for gaskets with PTFE fillers, emphasizing its importance for graphite fillings. This cutting-edge profile is expertly utilized in both raised and flat-faced flanges. The external ring not only provides exceptional radial strength to prevent blowouts but also serves as a compression stop, ensuring flawless functionality. Crafted from carbon steel—either painted or zinc-plated to resist corrosion—it can also be made from superior alloys for extreme temperature and harsh medium scenarios.
