Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Crafted with precision and expertise, this spiral wound gasket boasts a solid outer and inner ring designed to elevate performance to unparalleled heights. The ingeniously inserted inner ring not only boosts gasket performance but also ensures accurate centering on the flange face, safeguarding against the gasket imploding into the pipe during installation. This innovative design element shields the sealing component from extreme temperatures and harsh mediums, while filling the void between flanges to thwart flange erosion and minimize failure risks. Typically, the inner ring mirrors the alloy of the winding and complies with the DIN 2699 German standard, which mandates its inclusion in all spiral wound gaskets. Adhering to ASME B16.20 standards, inner rings are vital for gaskets with PTFE fillers and crucial for those with graphite fillers. Perfectly suited for raised and flat-faced flanges, the external guide ring imparts additional radial strength, preventing blowouts and serving as a compression stop. Often crafted from painted or zinc-plated carbon steel to resist corrosion, the outer ring can also be fashioned from specialized alloys to withstand higher temperatures and more demanding medium applications.
