SPIRAL WOUND GASKET
DETAILED DESCRIPTION:
Product Type:XINSEN-SD
Unmatched Features:
This exceptional spiral wound gasket is engineered with a robust outer and inner ring. An additional inner ring is meticulously inserted to significantly enhance the gasket's performance. This inner ring ensures precise centering on the flange face and mitigates the risk of implosion into the pipe during installation. It safeguards the sealing element against extreme temperatures and various mediums, filling the void between flanges to prevent erosion and reducing the likelihood of failure. Typically, the inner ring is crafted from the same high-grade alloy as the winding. In adherence to DIN 2699 standards (German), inner rings are mandatory for all spiral wound gaskets. For gaskets with PTFE filler, the ASME B16.20 standards mandate inner rings, and they are highly recommended for graphite fillers. This profile is optimally utilized in raised and flat faced flanges. The external ring, which offers additional radial strength, acts as a compression stop to prevent gasket blowout. Often crafted from carbon steel (either painted or zinc plated to avoid corrosion), the outer ring can also be made from specialized alloys for applications involving higher temperatures and more severe conditions.
