Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This remarkable spiral wound gasket is crafted with a robust solid outer and inner ring. A specially designed inner ring enhances the gasket's performance by providing crucial support, ensuring precise alignment on the flange face through its external guide ring. This inner ring, ingeniously incorporated to prevent any implosion into the pipe during installation, serves to protect the sealing element from extreme conditions and potential damage. It effectively fills the void between flanges, safeguarding against erosion and significantly diminishing the risk of failure. Typically composed of the same high-quality alloy as the winding, the inner ring's importance is underscored by the DIN 2699 German standard, which mandates its inclusion in all spiral wound gaskets. For gaskets featuring PTFE filler, the ASME B16.20 standards specify the necessity of inner rings, with their importance also acknowledged for graphite fillers. This profile is predominantly utilized in both raised and flat faced flanges. The external ring not only provides additional radial strength to avert gasket blowout but also acts decisively as a compression stop. Often made from carbon steel—either painted or zinc plated to withstand corrosion—the outer ring can also be customized from alloys for applications demanding higher temperature resistance and durability against severe mediums.
