Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience unparalleled sealing precision with our state-of-the-art spiral wound gasket, crafted with both solid outer and inner rings for superior durability. This innovative gasket design incorporates an inner ring, enhancing performance by preventing potential implosions during installation. This essential component shields the sealing element from extreme conditions, effectively filling voids between flanges to thwart erosion, and minimizing failure risks. Composed of the same robust alloy as the winding, the inner ring complies with the renowned DIN 2699 standard, mandating its presence in all spiral wound gaskets for optimal reliability. Adhering to ASME B16.20 standards, inner rings are indispensable for gaskets with PTFE fillers and vital for those with graphite fillers. Ideally suited for raised and flat-faced flanges, the external guide ring expertly centers the gasket on the flange face, offering additional radial strength to prevent blowouts and acting as a compression stop. The outer ring, typically fashioned from corrosion-resistant painted or zinc-plated carbon steel, can also be crafted from high-performance alloys, catering to high-temperature and severe medium applications.
