Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Unveil the exceptional design of this Semi-Metal Spiral Gasket with Inconel Winding and Mica Filler, offering an unparalleled blend of strength and precision. Equipped with both a solid outer and inner ring, this gasket includes an expertly inserted inner ring that significantly boosts its performance by ensuring ideal centering on the flange face. The inner ring's purpose is manifold: it prevents implosion during installation, shields the sealing element from extreme thermal and chemical conditions, fills voids to avert flange erosion, and minimizes failure risks. Constructed typically from the same durable alloy as the winding, it adheres to DIN 2699 standards and is essential for PTFE fillers as per ASME B16.20 standards, with significant importance for graphite fillers. This configuration is optimally suited for raised and flat-faced flanges. Complementing this is the robust external guide ring, crafted to provide additional radial strength, thwarting blowout and acting as a steadfast compression stop. Often made from corrosion-resistant carbon steel, this outer ring can also be tailored from specialized alloys for high-temperature and severe medium applications, making it a versatile choice for diverse industrial needs.
