Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing our ASME B16.20 Compliant Spiral Gasket with SS316 Winding, a superior sealing solution designed with precision and durability in mind. This state-of-the-art spiral wound gasket boasts a robust outer and inner ring configuration. The carefully engineered inner ring is integrated to significantly boost the gasket's performance, ensuring optimal centering on the flange face with the assistance of an external guide ring. By incorporating the inner ring, we eliminate the risk of gasket collapse into the pipe during installation and provide added protection against extreme conditions, thereby extending the lifespan of the sealing element. The inner ring, typically crafted from the same high-grade alloy as the winding, fills the gap between flanges, preventing flange erosion and enhancing the overall integrity of the seal. Adhering to the stringent DIN 2699 standards, this feature is essential for gaskets with PTFE fillers under ASME B16.20 regulations and is highly recommended for those with graphite fillers. Ideal for use in both raised and flat-faced flanges, the external ring significantly fortifies the gasket by offering excellent radial strength, thus averting blowout and serving as a reliable compression stop. Constructed from resilient carbon steel—available in painted or zinc-plated finishes to resist corrosion—or crafted from specialized alloys for high-temperature and aggressive medium environments, this gasket represents the pinnacle of engineering excellence and reliability.
