Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the impeccable design of our ASME B16.20 Spiral Gasket featuring superior PTFE and SS316 winding options. This gasket boasts an expertly integrated solid outer and inner ring, with an additional inner ring meticulously incorporated to elevate its performance. The external guide ring ensures precise centering of the gasket on the flange face. This innovative inner ring is crafted to eliminate the risk of imploding into the pipe during the installation process, offering robust protection to the sealing element from extreme temperatures and harsh mediums. By seamlessly filling the void between flanges, it also prevents flange erosion and significantly minimizes the chance of failure. Adhering to the DIN 2699 standard, which mandates inner rings in all spiral wound gaskets, our design ensures compliance for PTFE fillers as per ASME B16.20 standards, while also being highly recommended for graphite fillers. Particularly suited for raised and flat faced flanges, this profile showcases an external ring that enhances radial strength, preventing gasket blowout and functioning as a compression stop. The outer ring, typically constructed from carbon steel with paint or zinc plating to resist corrosion, can also be crafted from alloys for applications demanding higher temperatures and severe medium resilience.
