Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience unmatched performance with our spiral wound gasket, meticulously designed with a robust solid outer and inner ring. The addition of an inner ring significantly amplifies the gasket's performance. It ensures precise centering on the flange face, safeguarding against any implosion into the pipe during installation. This pivotal component shields the sealing element from extreme temperatures and diverse mediums, completely filling the void between flanges to thwart erosion and minimize failure risks. Typically crafted from the same alloy as the winding, the inner ring adheres to the DIN 2699 standard, which mandates its inclusion in all German spiral wound gaskets. Essential for PTFE filler gaskets per ASME B16.20 standards and crucial for graphite fillers, this feature is typically employed in both raised and flat faced flanges. The external ring further enhances radial strength, preventing blowouts while acting as a compression stop, crafted usually from carbon steel—painted or zinc plated for corrosion resistance—or from alloys for applications involving higher temperatures and more severe conditions.
