Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing the superior spiral wound gasket designed to excel in performance with its robust solid outer and inner rings. Ingeniously, we've integrated an inner ring to significantly boost the gasket's efficacy. This inclusion ensures precise centering on the flange face, offers protection from harsh conditions, and prevents the implosion risk during installation. Moreover, it fills the gap between flanges effectively, safeguarding against flange erosion and minimizing failure risks. Crafted usually from the same high-quality alloy as the winding, the inner ring is crucial, especially when dealing with PTFE fillers, as per ASME B16.20 standards, and is equally vital for graphite fillers. This gasket profile is ideally suited for raised and flat-faced flanges, providing unmatched reliability. Additionally, the external guide ring delivers enhanced radial strength, averting any possibility of blowout and serving as a dependable compression stop. While often made from corrosion-resistant painted or zinc-plated carbon steel, the outer ring can also be fashioned from specialty alloys for applications demanding higher temperatures and more challenging mediums.
