Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Unveil the exceptional Spiral Gasket, engineered meticulously with a robust dual-ring design, featuring both solid outer and inner rings. The precision-inserted inner ring elevates the gasket's capabilities, ensuring optimal performance by providing unwavering stability against installation stress and guarding against potential implosion into the pipe. This strategic addition shields the sealing element from harsh temperatures and chemicals, fills the flange void to avert erosion, and minimizes the risk of failure. Fabricated usually from the same alloy as the winding, the inner ring complies with the exacting DIN 2699 standard, mandating its presence in all spiral wound gaskets. For gaskets utilizing PTFE filler, ASME B16.20 standards stipulate the necessity of the inner ring, which is also deemed critical for those with graphite fillers. This design is adeptly applied in both raised and flat faced flanges. The external guide ring serves a dual purpose: reinforcing radial strength to thwart blowouts and acting as a reliable compression limiter. Typically constructed from carbon steel—either painted or zinc-plated to resist corrosion—the outer ring can also be fashioned from specialized alloys for heightened resilience in extreme environments and temperatures.
