SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This spiral wound gasket is engineered with a robust solid outer and inner ring. An additional inner ring is strategically inserted to significantly enhance gasket performance. This external guide ring ensures precise centering of the gasket on the flange face, providing seamless installation. The inner ring's purpose is to prevent the gasket from imploding into the pipe during installation, safeguarding the sealing element from extreme temperatures and harsh mediums. It efficiently fills the void between flanges, reducing erosion and minimizing the risk of failure. Typically, the inner ring matches the winding alloy, ensuring structural integrity. According to the stringent German DIN 2699 standard, inner rings are mandatory for all spiral wound gaskets. For gaskets with PTFE fillers, ASME B16.20 standards necessitate inner rings and are deemed crucial for graphite fillers. This design is ideal for raised and flat-faced flanges, with the external ring providing essential radial strength to avert gasket blowout, serving as a reliable compression stop. Carbon steel, often painted or zinc plated to resist corrosion, is commonly used for the outer ring, although alloys are available for applications requiring higher temperature and severe medium handling.
