SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This advanced spiral wound gasket is engineered with a solid outer and inner ring, complemented by an inserted inner ring designed to elevate gasket efficacy. The external guide ring meticulously aligns the gasket on the flange face for optimal performance. The inner ring serves as a vital component, preventing potential gasket implosion into the pipe during installation, safeguarding the sealing element against extreme temperatures and harsh mediums. It also fills the void between flanges to avert flange erosion and diminishes the risk of failure. Crafted usually from the same alloy as the winding, the inner ring adheres to the DIN 2699 standard, mandating its inclusion in all spiral wound gaskets. In compliance with ASME B16.20 standards, the inner ring is necessary for gaskets with PTFE filler and is crucial for those with graphite fillers. This sophisticated profile is ideal for both raised and flat-faced flanges, with the external ring providing extra radial strength to prevent blowout, doubling as a compression stop. Typically, the outer ring is made from carbon steel, coated or zinc-plated to thwart corrosion, though adaptable to alloy construction for high-temperature and rigorous medium scenarios.
