Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This remarkable spiral wound gasket is expertly engineered with a robust solid outer and inner ring, complemented by an innovative inner ring designed to elevate gasket performance to new heights. This essential component not only provides impeccable centering on the flange face but also safeguards against potential implosion into the pipe during installation. With its ability to shield the sealing element from harsh temperatures and corrosive environments, the inner ring effectively fills gaps between flanges, preventing erosion and mitigating the risk of failure. Typically crafted from the same alloy as the winding, the inner ring adheres to the stringent DIN 2699 (German) standards, ensuring unparalleled reliability in all spiral wound gaskets. As stipulated by ASME B16.20 standards, inner rings are mandatory for gaskets with PTFE filler and crucial for those with graphite fillers. This design is frequently employed in both raised and flat-faced flanges. The external guide ring enhances radial fortitude, thwarting gasket blowout and functioning as a reliable compression stop. Often constructed from durable carbon steel, either painted or zinc-plated for corrosion resistance, the outer ring can also be fashioned from advanced alloys to accommodate extreme temperatures and challenging applications.
