Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing our superior Spiral Wound Gasket, expertly engineered with a robust solid outer and inner ring for exceptional sealing performance. The enhanced design includes an inner ring, meticulously inserted to optimize gasket efficacy and precision. This inner ring is crucial for safeguarding the gasket against potential implosion into the pipe during installation, protecting the sealing element from the harshest temperatures and aggressive mediums, and meticulously filling the void between flanges to guard against flange erosion. It significantly minimizes the risk of failure, aligning with the stringent DIN 2699 standards. For gaskets with PTFE fillers, the ASME B16.20 standards mandate the presence of inner rings, and they are highly recommended for those with graphite fillers. Typically, the inner ring matches the alloy of the winding, enhancing cohesion and reliability. Employed in both raised and flat-faced flanges, this profile is your go-to choice for secure and efficient applications. The external guide ring offers pivotal radial strength against blowouts and serves as a crucial compression stop. Often crafted from corrosion-resistant carbon steel—or alloys for elevated temperatures and demanding environments—the outer ring ensures longevity and superior performance.
