Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing the ultimate in sealing technology: our Heavy-Duty Metal Spiral Wound, Semi-Metallic, Spiral Gasket for Tough Applications. This elite gasket features a robust solid outer and inner ring, meticulously engineered for peak performance. An expertly integrated inner ring significantly enhances the gasket's durability and fortifies it against extreme conditions. This essential component prevents implosion during installation, shields the sealing element from harsh temperatures and media, and fills the critical void between flanges to reduce erosion and risk of failure. Crafted to meet the rigorous German DIN 2699 standards, which mandate inner rings for all spiral wound gaskets, this design also aligns with ASME B16.20 regulations requiring an inner ring for PTFE fillers, and is deemed essential for graphite fillers as well. Optimized for both raised and flat-faced flanges, the external guide ring not only ensures perfect centering on the flange face but provides superior radial strength to counteract gasket blowouts while acting as a compression stop. The outer ring, typically forged from corrosion-resistant carbon steel, can alternatively be crafted from other alloys to withstand higher temperatures and more aggressive environments.
