Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the superior performance of our spiral wound gasket, expertly crafted with a robust solid outer and inner ring design. We've meticulously inserted a precision-engineered inner ring to significantly boost gasket performance, ensuring flawless alignment on the flange face via an external guide ring. This inner ring serves a pivotal role, preventing potential gasket implosion into the pipe during installation, shielding the sealing element from extreme temperatures and aggressive mediums. It proficiently fills the void between flanges, protecting against flange erosion, while substantially reducing failure risks. Crafted from the same durable alloy as the winding, the inner ring aligns with the rigorous DIN 2699 standard, mandating its inclusion in all spiral wound gaskets. For gaskets utilizing PTFE fillers, the ASME B16.20 standards specify the necessity of an inner ring, which is also deemed crucial for graphite fillers. This advanced profile is ideally suited for raised and flat-faced flanges. The external ring endows the gasket with enhanced radial strength to avert blowouts and functions as a reliable compression stop. Typically composed of carbon steel—with optional painting or zinc plating to thwart corrosion—the outer ring is adaptable, available in various alloys to cater to high-temperature and severe medium applications, ensuring resilience and extended durability.
