Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing an exceptional spiral wound gasket, meticulously crafted with a robust solid outer and inner ring for unparalleled reliability. This innovative design includes an expertly inserted inner ring to significantly boost performance and ensure precise alignment on the flange face through an external guide ring. Adding an inner ring is a strategic enhancement to avert the potential collapse of the gasket into the pipe during installation, safeguarding the sealing element against extreme temperatures and aggressive mediums. It effectively bridges the void between flanges, preventing flange erosion and minimizing the risk of failure. Typically composed of the same high-performance alloy as the winding, the inner ring adheres to the DIN 2699 standard (German), which mandates inner rings in all spiral wound gaskets, with ASME B16.20 standards further necessitating them for gaskets with PTFE filler and emphasizing their importance for those with graphite fillers. This versatile profile is ideally suited for raised and flat-faced flanges. Additionally, the external ring offers significant radial strength to avoid gasket blowout, serving as a compression stop. Often crafted from carbon steel—painted or zinc-plated to resist corrosion—it can also be manufactured from alloys for superior performance in higher temperature and more severe medium applications.
