Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Behold the pinnacle of sealing efficiency with our spiral wound gasket, meticulously crafted with a robust solid outer and inner ring. Elevating gasket performance, an inner ring has been ingeniously incorporated to optimize functionality. Its design ensures precise centering on the flange face with an external guide ring, safeguarding against implosion during installation. This protective inner ring shields the sealing element from extreme temperatures and diverse mediums. It also fills voids between flanges, preventing erosion and reducing the risk of failure. Crafted to match the alloy of the winding, inner rings comply with DIN 2699 standards and are a requirement for gaskets with PTFE filler per ASME B16.20 standards, serving as a crucial recommendation for graphite fillers. Ideal for both raised and flat-faced flanges, its external ring offers additional radial strength, preventing blowout and serving as a compression stop. Typically made from carbon steel, painted, or zinc plated for corrosion resistance, this ring can also be crafted from alloys for enhanced performance in high-temperature and rigorous medium applications.
