Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This spiral wound gasket features a robust construction with solid outer and inner rings. An integral inner ring has been meticulously incorporated to significantly boost the gasket's performance and reliability. This inner ring plays a crucial role in precisely centering the gasket on the flange face, eliminating risks of implosion into the pipe during installation, safeguarding the sealing element against extreme temperatures and harsh mediums. Furthermore, it effectively fills the void between flanges to prevent erosion, thereby bolstering the overall gasket integrity. As prescribed by the stringent DIN 2699 and ASME B16.20 standards, the inner ring is crafted from the same resilient alloy as the winding and is indispensable for gaskets with PTFE and highly recommended for those with graphite fillers. The external guide ring adds an extra layer of radial strength, preventing blowouts and acting as a reliable compression stop. This sophisticated profile is ideally designed for raised and flat-faced flanges, with the outer ring typically manufactured from carbon steel—with optional paint or zinc plating for corrosion resistance—or robust alloys for high-temperature and severe medium applications.
