Product Description

SPIRAL WOUND GASKET: A Revolution in Sealing Technology

Product Type:XINSEN-SD: Advanced Engineering for Optimal Performance
Features:
Introducing a meticulously engineered spiral wound gasket that features both a robust solid outer and an inner ring. Our innovation includes a specially inserted inner ring designed to significantly enhance gasket performance. The external guide ring is precisely crafted to ensure the gasket is accurately centered on the flange face. The inner ring serves multiple crucial functions: it prevents the gasket from potentially imploding into the pipe during installation, offers protection to the sealing element from extreme temperatures and harsh mediums, fills the void between flanges to avert erosion, and minimizes the likelihood of failure. Typically manufactured from the same alloy as the winding, the inner ring adheres to the stringent DIN 2699 standard (German), which mandates inner rings in all spiral wound gaskets. As per ASME B16.20 standards, inner rings are essential for gaskets using PTFE fillers and are highly recommended for those with graphite fillers. This profile is optimally used in raised and flat-faced flanges. Additionally, the external ring provides enhanced radial strength to prevent gasket blowout and serves as a compression stop. Commonly employed in both raised and flat-faced flanged applications, the outer ring is often crafted from carbon steel, which can be painted or zinc-plated to resist corrosion, or made from specialized alloys for operations involving higher temperatures and more severe mediums.
