SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This spiral wound gasket, enhanced with a robust solid outer and inner ring, stands as a paragon of superior performance. The innovative inclusion of an inner ring not only elevates the gasket's reliability but also ensures meticulous centering on the flange face through its external guide ring. The inner ring, harmoniously constructed from the same alloy as the winding, plays a crucial role in averting potential implosion into pipes during installation. It offers an indispensable shield for the sealing element against extreme temperature fluctuations and harsh mediums, fills flange voids to impede erosion, and fortifies the gasket against failure. Adhering to the esteemed DIN 2699 standards, inner rings are a staple in all spiral wound gaskets, particularly vital for those with PTFE and graphite fillers as per ASME B16.20 guidelines. Designed for both raised and flat-faced flanges, the external ring imparts additional radial strength, averting blowout while acting as an effective compression stop. Typically crafted from carbon steel (with protective paint or zinc plating to deter corrosion), the outer ring can also be fashioned from advanced alloys, catering to high-temperature and severe environment applications.
