SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This superior spiral wound gasket is engineered with robust outer and inner rings. Notably, an inner ring is strategically introduced to amplify gasket performance while an external guide ring seamlessly centers the gasket on the flange face. The inner ring plays a crucial role in averting gasket implosion into the pipe during installation, safeguarding the sealing elements from extreme temperatures and corrosive mediums, bridging the void between flanges to mitigate flange erosion, and minimizing failure risks. Typically, the inner ring matches the winding alloy. The DIN 2699 standard (German) mandates the inclusion of inner rings in all spiral wound gaskets. Inner rings are indispensable for gaskets with PTFE filler in compliance with ASME B16.20 standards and are highly recommended for those with graphite fillers. This profile is customarily utilized in raised and flat-faced flanges. The external ring endows additional radial robustness to avert gasket blowout and serves as a compression limiter. It is frequently employed in raised and flat-faced flanges. The outer ring is usually crafted from carbon steel, which is either painted or zinc plated to resist corrosion, but can also be constructed from alloys for applications involving elevated temperatures and harsher mediums.
