Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Presenting a state-of-the-art spiral wound gasket, designed meticulously with a robust outer and inner ring configuration. The inclusion of an inner ring not only boosts the gasket's durability but also ensures supreme stability by preventing possible implosions into the pipe during installation. This protective measure shields the sealing element from extreme temperatures and aggressive media, filling the flange gaps to avert flange erosion, and minimizing the risk of failure. Typically crafted from the same high-quality alloy as the winding, the inner ring satisfies the stringent DIN 2699 standard, mandating its presence in all spiral wound gaskets. For those with PTFE fillers, ASME B16.20 standards necessitate inner rings, which are also deemed crucial for gaskets with graphite fillers. This versatile profile adapts flawlessly to both raised and flat-faced flanges. Additionally, the outer guide ring offers enhanced radial strength, acting as a fail-safe to prevent blowouts and serving as a compression limit. Often constructed from carbon steel with paint or zinc plating for corrosion resistance, or from specialized alloys for more demanding high-temperature and severe media applications, this outer ring ensures resilient performance in varied environments.
