SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This exceptional spiral wound gasket is engineered with a robust outer and inner ring. It is designed to excel in performance with an inserted inner ring that elevates its effectiveness. The external guide ring meticulously centers the gasket on the flange face. The inner ring's purpose is pivotal—it prevents the potential implosion of the gasket into the pipe during installation, shields the sealing element from extreme conditions, fills voids between flanges to avert flange erosion, and mitigates failure risks. Crafted typically from the same alloy as the winding, the inner ring adheres to the DIN 2699 standard, which mandates this feature in all spiral wound gaskets. For gaskets with PTFE fillers, ASME B16.20 standards necessitate the inclusion of inner rings, and these are deemed crucial for graphite fillers. This profile is ideally suited for raised and flat-faced flanges. The external ring enhances radial strength, acting as a safeguard against gasket blowout and functioning as a compression stop. Often fashioned from carbon steel—either painted or zinc plated to combat corrosion—it can also be crafted from specialized alloys for high-temperature and demanding medium applications.
