Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This spiral wound gasket, a marvel of engineering, features a robust solid outer and inner ring to ensure unparalleled sealing performance. The inclusion of an inner ring is a game-changer, enhancing the gasket's capabilities by precisely centering it on the flange face. This critical element not only mitigates the risk of gasket implosion into the pipe during installation but also shields the sealing component from extreme temperatures and harsh mediums. It masterfully fills the void between flanges, thus thwarting flange erosion and significantly reducing failure risks. Typically crafted from the same high-grade alloy as the winding, the inner ring adheres to the stringent DIN 2699 German standard, which mandates its presence in all spiral wound gaskets. For those utilizing PTFE fillers, inner rings are a necessity under ASME B16.20 standards, and they are highly recommended for graphite fillers. This innovative profile excels in both raised and flat-faced flanges, with the outer ring providing additional radial strength to avert blowout and functioning as a reliable compression stop. Crafted often from carbon steel, which is either painted or zinc-plated to guard against corrosion, the outer ring can also be tailored from advanced alloys for applications involving higher temperatures and more severe conditions.
