Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the engineering marvel of our spiral wound gasket! This advanced sealing solution is equipped with a robust solid outer and inner ring. The cleverly integrated inner ring is engineered to elevate performance by offering protection against extreme conditions while ensuring flawless installation. It prevents gasket implosion, shields the sealing element from extreme temperatures and harsh mediums, and effectively fills the void between flanges to guard against erosion. The inner ring, crafted to match the alloy of the winding, stands as a testament to precision and durability. Adhering to the DIN 2699 standard, these inner rings are pivotal for PTFE fillers as per ASME B16.20 standards, and nearly indispensable for graphite fillers. Our gasket profile excels in both raised and flat-faced flanges. Adding to its resilience is the external guide ring, which provides unmatched radial strength, acts as a compression stop, and prevents blowouts with ease. Typically made of carbon steel with protective finishes like paint or zinc plating, the outer ring is also available in high-performance alloys for those demanding higher temperature and severe medium applications. Experience the unparalleled reliability and strength designed for industrial excellence.
