Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This exceptional spiral wound gasket is meticulously engineered with both a solid outer ring and an inner ring to deliver superior performance. The added inner ring is a strategic enhancement, ensuring optimized gasket functionality by preventing possible implosions into the pipe during installation and safeguarding the sealing element from extreme temperatures and harsh mediums. It masterfully fills the void between flanges, mitigating flange erosion and significantly reducing the likelihood of failure. Typically composed of the same resilient alloy as the winding, the inner ring adheres to the stringent DIN 2699 standard (German) for heightened reliability. The ASME B16.20 standards particularly mandate inner rings for gaskets with PTFE filler and underscore their importance for those with graphite fillers. This profile is expertly suited for use in both raised and flat-faced flanges. The robust external guide ring precisely positions the gasket on the flange face, offering additional radial strength that protects against blowouts, while functioning as a dependable compression stop. Often crafted from carbon steel, which may be painted or zinc plated for corrosion protection, the outer ring can also be constructed from specialized alloys to withstand higher temperatures and more demanding environments.
