Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This exceptional spiral wound gasket is engineered with precision, featuring a robust outer and inner ring to ensure superior performance. The inner ring, skillfully incorporated, amplifies the gasket's efficiency by preventing implosion into the pipe during installation. It offers optimal protection to the sealing element against extreme temperatures and aggressive mediums, adeptly fills voids between flanges to avert flange erosion, and significantly mitigates the risk of failure. Typically crafted from the same alloy as the winding, the inner ring complies with the rigorous DIN 2699 standard, mandated for all spiral wound gaskets in Germany. Furthermore, according to the stringent ASME B16.20 standards, PTFE-filled gaskets necessitate this inner ring, and it is also deemed vital for those with graphite fillers. This profile seamlessly adapts to both raised and flat-faced flanges. Additionally, the external guide ring performs brilliantly by providing additional radial strength to thwart gasket blowout, and it functions efficiently as a compression stop. Customarily constructed from carbon steel, which can be either painted or zinc plated to resist corrosion, the outer ring can also be fashioned from alloys for applications involving higher temperatures or more severe mediums.
