Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Experience the pinnacle of sealing excellence with our meticulously engineered spiral wound gasket, featuring a robust solid outer and inner ring design. Enhanced performance is guaranteed with the strategic inclusion of an inner ring to prevent implosion into the pipe during installation and protect against extreme temperatures and harsh mediums. This inner ring also fills the void between flanges, safeguarding against erosion and reducing the risk of failure. Expertly crafted, the inner ring matches the alloy of the winding, adhering to the esteemed DIN 2699 standard, and is essential for gaskets with PTFE fillers as per ASME B16.20 standards, crucial even for graphite fillers. Perfectly suited for both raised and flat-faced flanges, the external guide ring offers unmatched radial strength, preventing blowout while doubling as a precise compression stop. Typically constructed of corrosion-resistant carbon steel that is either painted or zinc-plated, the outer ring can also be customized in alloys to withstand higher temperatures and severe applications.
