Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Discover the exceptional capabilities of our spiral wound gasket, meticulously engineered with both a solid outer and inner ring. The addition of an innovative inner ring significantly boosts the gasket's performance, ensuring optimal alignment with the flange face through its expertly designed external guide ring. This inner ring is crucial for preventing implosion into the pipe during installation, safeguarding the sealing element against extreme temperatures and challenging mediums. It adeptly fills the gap between flanges, reducing erosion risks and minimizing potential failure. Typically crafted from the same robust alloy as the winding, the inner ring adheres to the German DIN 2699 standard, which mandates its inclusion in all spiral wound gaskets. For gaskets featuring PTFE filler, ASME B16.20 standards necessitate the inner ring, which is also highly recommended for graphite fillers. This sophisticated profile is ideally suited for both raised and flat-faced flanges. The external ring enhances radial strength, preventing blowout and serving as an effective compression stop. Often composed of carbon steel, it is meticulously painted or zinc-plated to resist corrosion, or crafted from specialized alloys to withstand higher temperatures and more severe mediums.
