Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the robust and meticulously engineered Standardized Metal Spiral Wound, Semi-Metallic, Spiral Gasket for Compliance, equipped with unparalleled features to meet the demanding needs of your applications. This sophisticated gasket design incorporates a solid outer and inner ring with an added inner ring to significantly boost performance. This ingenious inclusion ensures superior protection by preventing potential gasket implosions during installation, shielding the sealing element from extreme temperatures and harsh mediums, and effectively filling voids between flanges to avert erosion. The inner ring, crafted from the same material as the winding, adheres to the esteemed DIN 2699 standard, mandating its presence in all spiral wound gaskets, particularly when using PTFE fillers as per ASME B16.20 standards. This is also crucial for graphite fillers. Optimally tailored for raised and flat-faced flanges, the external guide ring not only guarantees precise centering on flange faces but also imparts additional radial strength, serving as a compression stop to combat gasket blowout. Typically composed of carbon steel—painted or zinc-plated to combat corrosion—it can also be crafted from higher-grade alloys for extreme temperatures and challenging medium applications.
