Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This revolutionary spiral wound gasket, featuring a robust solid outer and inner ring, represents the pinnacle of sealing technology. Uniquely, an inner ring is strategically incorporated to exponentially boost gasket performance. This vital element not only ensures precise centering on the flange face but also shields the sealing component from extreme temperatures and harsh mediums. It meticulously fills any void between flanges, mitigating erosion risks and significantly diminishing the chance of gasket failure. Crafted typically from the same alloy as the winding, the inner ring adheres to the stringent DIN 2699 standards (German), which mandate inner rings in all spiral wound gaskets. According to the ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and are considered crucial for those with graphite fillers. This exceptional profile is predominantly employed in raised and flat-faced flanges, with the external guide ring offering enhanced radial strength and acting as a fail-safe compression stop to avert gasket blowout. While the outer ring is generally composed of corrosion-resistant carbon steel (either painted or zinc plated), it can also be crafted from alloys to withstand higher temperatures and more demanding applications.
