SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
Our premium DONHONSIL Spiral Gasket, featuring robust solid outer and inner rings, is designed to elevate your sealing solutions to new heights of reliability. Engineered with an inserted inner ring, this gasket ensures superior performance by precisely centering itself on the flange face. This innovative design not only prevents potential implosion into the pipe during installation but also safeguards the sealing element from harsh temperatures and aggressive mediums. The inner ring seamlessly fills the gap between flanges, averting flange erosion and significantly reducing the risk of failure. Crafted from the same high-grade alloy as the winding, the inner ring complies with the stringent DIN 2699 (German) standards and is mandatory for gaskets with PTFE fillers in line with ASME B16.20 standards, while being highly recommended for graphite fillers. This configuration excels in raised and flat-faced flanges. The external guide ring adds an extra layer of radial strength, acting as a safeguard against gasket blowout and functioning as a reliable compression stop. Typically constructed from carbon steel, either painted or zinc-plated to combat corrosion, the outer ring can also be fabricated from specialized alloys for applications involving extreme temperatures and demanding mediums.
