Product Description

Product Description

SPIRAL WOUND GASKET

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Our spiral wound gasket is a marvel of engineering, featuring robust outer and inner rings designed for superior performance. The addition of an inner ring is a revolutionary enhancement, boosting the gasket's capabilities by preventing implosion into the pipe during installation. It acts as a guardian, shielding the sealing element from harsh temperatures and aggressive media. By filling the gap between flanges, it defends against erosion, reducing the likelihood of failure. Crafted typically from the same alloy as the spiral winding, the inner ring complies with DIN 2699 (German) standards and is mandatory for gaskets with PTFE fillers under ASME B16.20 norms, also deemed essential for those with graphite fillers. This gasket configuration is ideally suited for raised and flat-faced flanges. The external guide ring further fortifies the gasket with additional radial strength, averting blowouts and functioning as a reliable compression stop. Often constructed from carbon steel-either painted or zinc-plated to resist corrosion-these outer rings may be formed from various alloys for enduring higher temperatures and more demanding media applications.
