SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
Introducing a marvel of engineering: this spiral wound gasket comes equipped with a robust solid outer and inner ring, with a strategically inserted inner ring to significantly boost performance. The external guide ring ensures precise centering on the flange face. This innovation prevents gasket collapse during installation, defends the sealing element from extreme conditions, mitigates erosion between flanges, and minimizes failure risk. The inner ring, crafted from the same alloy as the winding, adheres to the DIN 2699 standard (German), which mandates inner rings in all spiral wound gaskets. According to ASME B16.20 standards, inner rings are a necessity for gaskets with PTFE filler and highly recommended for graphite fillers. This advanced profile excels in both raised and flat-faced flanges. The external ring provides superior radial strength, averting blowout and acting as a crucial compression limiter. Typically composed of carbon steel—either painted or zinc-plated to thwart corrosion—it can also be crafted from alloys to accommodate higher temperatures and more demanding environments.
