SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This exceptional spiral wound gasket is engineered with a robust solid outer and inner ring. An additional inner ring is meticulously inserted to significantly elevate gasket performance. This innovative feature aids in precisely centering the gasket on the flange face while bolstering protection. The inner ring is crucial to preventing the gasket from collapsing into the pipe during setup, shielding the sealing element from harsh temperatures and aggressive media, bridging the gap between flanges to avert flange erosion, and lowering the risk of gasket failure. Typically crafted from the same high-grade alloy as the winding, the inner ring adheres to the DIN 2699 standard from Germany, mandating its inclusion in all spiral wound gaskets. For gaskets with PTFE filler, ASME B16.20 standards necessitate an inner ring, and it's highly recommended for graphite fillers as well. This versatile profile suits both raised and flat-faced flanges. The external ring provides enhanced radial strength, preventing blowout and acting as a compression limiter. Outer rings are often composed of corrosion-resistant painted or zinc-plated carbon steel, though alloys are also available for high-temperature and demanding applications.
