Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This exceptional spiral wound gasket is meticulously engineered with a robust solid outer and inner ring. The inner ring is an innovative insertion designed to significantly enhance gasket performance. Moreover, an external guide ring ensures precise centering of the gasket on the flange face. The inner ring is crucial as it safeguards against potential implosion into the pipe during installation, shields the sealing element from extreme temperatures and harsh mediums, fills the void between flanges to avert flange erosion, and minimizes the risk of failure. Typically, the inner ring is crafted from the same alloy material as the winding, with adherence to the DIN 2699 standard (German), which mandates inner rings for all spiral wound gaskets. For gaskets with PTFE filler, inner rings are required by ASME B16.20 standards and are deemed essential for those with graphite fillers. This profile is ideally suited for raised and flat-faced flanges. The external ring is crafted to impart added radial strength, preventing gasket blowout and serving as a compression stop. This profile is regularly employed in raised and flat-faced flanged settings. While the outer ring is commonly constructed from carbon steel—painted or zinc-plated to combat corrosion—it can also be made from alloys to meet the demands of higher temperature and more aggressive medium applications.
