Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing the superior James Walker Gasket with Spiral Winding and PTFE Filler Material, crafted to meet the rigorous demands of industrial applications. This exceptional spiral wound gasket is engineered with a robust outer and inner ring. The inclusion of an inner ring not only enhances the gasket's operational performance but also ensures precision alignment on the flange face with its external guide ring. The inner ring, crafted from the same premium alloy as the winding, is meticulously designed to prevent the gasket from imploding into the pipe during installation. It safeguards the sealing element against extreme temperatures and harsh mediums, effectively fills the void between flanges to avert erosion, and significantly reduces the risk of failure. Compliant with the German DIN 2699 standard, inner rings are an essential feature of all spiral wound gaskets. According to ASME B16.20 standards, they are mandatory for gaskets with PTFE filler and highly recommended for those with graphite fillers. This profile is ideally suited for both raised and flat-faced flanges. For added durability, the external ring provides superior radial strength, preventing gasket blowout and serving as a reliable compression stop. Typically fabricated from carbon steel—enhanced with paint or zinc plating to resist corrosion—the outer ring can be customized using alloys for applications involving higher temperatures and more severe conditions.
