Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Crafted with precision, this spiral wound gasket boasts a robust design featuring solid outer and inner rings. An expertly inserted inner ring amplifies the gasket's performance, ensuring flawless functionality. This essential component accurately centers the gasket on the flange face, preventing the risk of implosion into the pipe upon installation. It offers exceptional protection for the sealing element against extreme temperatures and harsh mediums, effectively fills voids between flanges to guard against erosion, and significantly reduces failure risks. The inner ring, crafted from the same robust alloy as the winding, adheres to the esteemed DIN 2699 German standard, mandating its presence in all spiral wound gaskets. For gaskets employing PTFE fillers, the ASME B16.20 standards necessitate an inner ring, highlighting its importance, especially for graphite fillers. This premium profile is ideally suited for both raised and flat-faced flanges. Additionally, the external guide ring imparts extra radial strength, acting as a steadfast compression stop to avert gasket blowouts. Often constructed from durable carbon steel—painted or zinc plated for corrosion resistance—the outer ring can also be made from special alloys to withstand higher temperatures and more severe mediums, ensuring unmatched reliability.
