Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the exceptional engineering behind this spiral wound gasket, crafted with a robust outer and inner ring that guarantee optimal performance. Our innovative design includes an inner ring to significantly boost gasket functionality, preventing any risk of implosion into the pipe during installation. This crucial component not only shields the sealing element from extreme temperatures and harsh mediums but also fills the void between flanges to avert erosion and minimize failure risks. Crafted typically from the same alloy as the winding, the inner ring complies with the German DIN 2699 standard, which mandates its inclusion in all spiral wound gaskets. In accordance with ASME B16.20 standards, an inner ring is indispensable for gaskets with PTFE filler and crucial for those with graphite fillers, ensuring unmatched reliability. This configuration excels in both raised and flat-faced flanges. The external guide ring, often fashioned from carbon steel and either painted or zinc-plated for corrosion resistance, delivers enhanced radial strength to prevent blowout while serving as a compression stop. For applications demanding higher temperature tolerance and more severe mediums, outer rings made from advanced alloys are available, highlighting versatility and endurance.
