SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This spiral wound gasket is engineered with a robust outer and inner ring. An inner ring is incorporated to significantly boost gasket performance by ensuring precise alignment on the flange face through an external guide ring. This inner ring is crucial for preventing gasket implosion into the pipe during installation, safeguarding the sealing element against high temperatures and harsh mediums, and filling the void between flanges to avert flange erosion, thereby minimizing the risk of failure. Typically, this inner ring is crafted from the same premium alloy as the winding. According to the DIN 2699 standard (German), the inclusion of inner rings is mandatory in all spiral wound gaskets. Inner rings are essential for gaskets with PTFE filler per ASME B16.20 standards and highly recommended for those with graphite fillers. This design is ideally suited for application in raised and flat-faced flanges. The external ring provides vital radial strength, preventing gasket blowout and functioning as a compression boundary. This configuration is typically deployed in raised and flat-faced flanges. Commonly constructed from carbon steel, either painted or zinc-plated to prevent corrosion, the outer ring can also be composed of alloys for enhanced temperature resistance and compatibility with more severe mediums.
