Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing our Semi-Metal Spiral Gasket, a marvel of engineering precision and reliability, featuring both solid outer and inner rings for heightened performance and durability. An expertly inserted inner ring elevates gasket efficiency by accurately centering it on the flange face, safeguarding against potential implosion during installation. This innovative design also shields the sealing element from harsh temperatures and aggressive mediums. It skillfully fills voids between flanges, thus preventing erosion, while significantly minimizing failure risks. Typically, the inner ring is crafted from the same robust alloy as the winding, meeting the stringent German DIN 2699 standards for all spiral wound gaskets. Inner rings are indispensable for gaskets with PTFE fillers as per ASME B16.20 standards and are crucial for graphite fillers. This exceptional profile is ideally suited for both raised and flat-faced flanges, offering unmatched compatibility and performance. Furthermore, the external ring enhances radial strength, effectively preventing gasket blowout and serving as a reliable compression stop. Often composed of carbon steel with protective painting or zinc plating to resist corrosion, the outer ring can also be tailored from alloys for applications involving higher temperatures and more severe conditions.
