Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience unparalleled sealing efficiency with our state-of-the-art spiral wound gasket, meticulously engineered to include both a robust solid outer and inner ring. The addition of an inner ring not only bolsters gasket performance but also ensures precision alignment on the flange face with an expertly crafted external guide ring. This enhancement is paramount, preventing potential implosion into the pipe during installation while safeguarding the sealing element from extreme conditions. Our inner ring provides a crucial protective barrier that fills voids between flanges, averting flange erosion and mitigating failure risks. Crafted with the same high-quality alloy as the winding, our inner ring aligns with the DIN 2699 standard, mandating inner rings in all spiral wound gaskets for enhanced security. According to ASME B16.20 standards, it is indispensable for gaskets with PTFE fillers, and strongly recommended for those with graphite fillers. Designed for versatility, this profile is ideally suited for both raised and flat-faced flanges. The external ring, often crafted from durable carbon steel, adds an extra layer of radial strength to thwart gasket blowouts and functions as a compression limiter. It can also be manufactured from advanced alloys to withstand higher temperatures and more demanding environments, ensuring longevity and reliability in every application.
