Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This spiral wound gasket boasts a robust design with both solid outer and inner rings to ensure maximum durability and performance. The inclusion of an inner ring is a strategic advancement, enhancing the gasket's reliability by preventing potential implosion into pipes during installation. It expertly shields the sealing element from extreme thermal and medium conditions, fills gaps between flanges to avert erosion, and crucially minimizes the chance of gasket failure. Crafted usually from the same resilient alloy as the winding, the inner ring adheres to DIN 2699 standards, which mandates its presence in all spiral wound gaskets, particularly when PTFE filler is used as per ASME B16.20 standards, and is deemed essential for graphite fillers as well. This innovative profile is adeptly suited for use in both raised and flat-faced flanges. Furthermore, the external guide ring not only ensures precise centering on the flange face but also contributes vital radial strength, acting as a safeguard against gasket blowout and functioning as a compression limiter. Typically fashioned from corrosion-resistant carbon steel (either painted or zinc-plated), the outer ring can also be crafted from specialized alloys to withstand higher temperatures and more demanding environments.
