Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This cutting-edge spiral wound gasket is expertly engineered with a robust solid outer ring and an integrated inner ring to amplify its performance in high-stakes environments. The intelligently inserted inner ring not only prevents the risk of gasket implosion during installation but also shields the sealing element from extreme temperatures and aggressive media. It effectively fills voids between flanges, thus safeguarding against flange erosion and minimizing the chance of failure. Crafted typically from the same high-quality alloy as the winding, the inner ring adheres to the rigorous DIN 2699 (German) standard and is indispensable for gaskets with PTFE filler per ASME B16.20 standards, while also crucial for graphite fillers. Designed for raised and flat-faced flanges, the external guide ring precisely positions the gasket on the flange face and reinforces radial strength to thwart gasket blowout. Additionally, it serves as a reliable compression stop. The outer ring, typically composed of carbon steel with anti-corrosive finishes like paint or zinc plating, can be tailored from specialized alloys for applications demanding high temperatures and severe conditions.
