Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
The Spiral Wound Gasket is expertly engineered with a robust combination of a solid outer and inner ring to elevate its sealing capabilities. An inner ring has been meticulously inserted to amplify performance, and an exterior guide ring ensures precise centering on the flange face. This essential inner ring serves multiple protective functions: it mitigates the risk of the gasket collapsing into the pipe during installation; shields the sealing element from rigorous temperatures and media; fills any voids between flanges to avert flange erosion; and minimizes failure potential. Constructed typically from the same alloy as the winding, the inner ring adheres to the DIN 2699 standard (German), which mandates its presence in all spiral wound gaskets. For gaskets utilizing PTFE filler, ASME B16.20 standards necessitate an inner ring, and it is highly recommended for those with graphite fillers. This profile is ideally suited for use in both raised and flat-faced flanges. The outer ring, a strategic component, not only provides additional radial strength to avert blowouts but also functions as a compression stop. Frequently crafted from carbon steel—either painted or zinc-plated to resist corrosion—or from alloys for demanding temperature and medium conditions, the external ring is integral to the gasket's structural integrity and durability.
