Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the cutting-edge design of our Semi-Metal Spiral Gasket with PTFE Filler and SS347 Winding, perfected for robust performance and reliability. This state-of-the-art gasket boasts a solid outer and inner ring, with an expertly inserted inner ring to boost performance. The external guide ring meticulously centers the gasket on the flange face, ensuring precision. The inner ring plays a crucial role by preventing the gasket from imploding into the pipe during installation, safeguarding the sealing element against extreme temperatures and harsh mediums. Additionally, it fills the void between flanges to deter flange erosion, significantly lowering the risk of failure. Crafted usually from the same high-quality alloy as the winding, this inner ring complies with the DIN 2699 standard (German) which mandates inner rings in all spiral wound gaskets. As per ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and are highly recommended for graphite fillers. This advanced profile is ideal for use in both raised and flat faced flanges. The outer ring, often made of carbon steel and optionally painted or zinc-plated for corrosion resistance, provides superior radial strength to avert gasket blowouts and functions as a compression limiter. For demanding applications with higher temperatures and severe mediums, alloy construction options are available. Experience enhanced durability and superior performance with this meticulously designed gasket.
