Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This advanced spiral wound gasket is ingeniously crafted with a solid outer and inner ring, yet features an enhanced inner ring to significantly boost performance. This inner ring is meticulously inserted to avert potential gasket implosion during installation, safeguard the integral sealing element from extreme temperatures and harsh mediums, and seamlessly occupy the void between flanges to prevent flange erosion, thereby reducing failure risks. Crafted typically from the same high-grade alloy as the winding, the inner ring adheres to the rigorous DIN 2699 standard specifications, mandating inner rings in all spiral wound gaskets. According to ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and highly recommended for those with graphite fillers. This specialized profile is predominantly implemented in raised and flat faced flanges. Furthermore, the external guide ring not only ensures precise centering on flange faces but also furnishes additional radial strength to thwart gasket blowout and serves as a vital compression stop. Constructed often from robust carbon steel, either painted or zinc plated to resist corrosion, the outer ring can also be fabricated from alloys to withstand higher temperatures and more severe mediums.
