Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover an innovation in sealing solutions with our spiral wound gasket, featuring robust solid outer and inner rings for unmatched durability. The addition of an inner ring elevates the gasket's performance, precisely centering it on the flange face with an external guide ring. This strategic inner ring insertion wards off the risk of the gasket imploding into the pipe during installation, shields the sealing element from extreme temperatures and aggressive media, fills flange voids to prevent erosion, and lowers the risk of failure. Typically crafted from the same alloy as the winding, the inner ring complies with the DIN 2699 standard (German), mandating its presence in all spiral wound gaskets. ASME B16.20 standards stipulate inner rings for gaskets with PTFE fillers and advocate their significance for graphite fillers. Perfect for raised and flat-faced flanges, the external ring enhances radial strength, averting gasket blowout, and functions as a compression stop. Carbon steel often constitutes the outer ring, painted or zinc-plated to resist corrosion, however, for higher temperatures and more demanding media applications, alloy compositions are available. This advanced profile is your go-to for optimum sealing.
