Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing our exceptional spiral wound gasket with robust outer and inner rings! This innovative design incorporates a strategically inserted inner ring, significantly boosting the gasket's performance and ensuring precise centering on the flange face with an external guide ring. This inner ring is a critical feature, preventing potential gasket implosion during installation, safeguarding the sealing element from extreme conditions, filling voids between flanges to shield against erosion, and minimizing failure risks. Typically composed of the same alloy as the winding, the inner ring adheres to the DIN 2699 German standard, which mandates inner rings for all spiral wound gaskets. For gaskets with PTFE filler, ASME B16.20 standards require inner rings, deemed vital for graphite fillers too. Ideal for both raised and flat-faced flanges, this gasket's external ring provides additional radial strength, preventing blowouts and acting as a compression stop. Often constructed from carbon steel with protective painting or zinc plating to combat corrosion, the outer ring can be crafted from high-grade alloys for elevated temperature and challenging medium applications.
