Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing our state-of-the-art spiral wound gasket, meticulously designed for optimal performance. This premium gasket is equipped with a robust outer and inner ring for maximum durability. The enhanced inner ring is ingeniously added to bolster gasket efficiency, preventing potential implosion during installation and safeguarding the sealing element from extreme conditions. It fills the flange voids, thus averting flange erosion and minimizing failure risks. Crafted from the same high-quality alloy as the winding, the inner ring adheres to the strict DIN 2699 standards and is mandatory for gaskets with PTFE filler per ASME B16.20 specifications, and highly recommended for graphite fillers. Perfectly suited for raised and flat-faced flanges, this profile is complemented by an external guide ring that precisely centers the gasket and provides extra radial strength to avert blowout, acting as a decisive compression stop. Typically constructed from corrosion-resistant carbon steel, the outer ring is also available in alloys for high-temperature and intense medium environments, ensuring unrivaled reliability and longevity.
