Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing our top-tier spiral wound gasket, a marvel of engineering precision, featuring robust solid outer and inner rings. Ingeniously, an inner ring is integrated to elevate gasket performance by providing a steadfast center on the flange face. This addition is critical to avert any scenario where the gasket might implode into the pipe during installation. It serves as a guardian for the sealing element against extreme temperatures and aggressive mediums, while also filling the void between flanges to stave off flange erosion and mitigate any chances of failure. Typically crafted from the same resilient alloy as the winding, the inner ring meets the stringent DIN 2699 German standard and is imperative for PTFE fillers per ASME B16.20 standards. Graphite fillers also find this enhancement invaluable. The profile is adeptly designed for both raised and flat-faced flanges. The external guide ring further fortifies radial strength, ensuring the gasket's integrity under pressure and acting as a compression stop. Commonly constructed from corrosion-resistant carbon steel, whether painted or zinc-plated, the outer ring can also be fashioned from high-temperature alloys for extreme applications.
