Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This exceptional spiral wound gasket is designed with a robust solid outer and inner ring, with an added inner ring for unmatched performance enhancement. This inner ring is expertly inserted to prevent implosion into the pipe during installation, providing superior protection to the sealing element against extreme temperatures and various mediums. It effectively fills the void between flanges, defending against flange erosion and significantly minimizing the risk of failure. Crafted from the same high-quality alloy as the winding, the inclusion of this inner ring is mandated by the prestigious DIN 2699 standard (German) and is essential for gaskets with PTFE filler as per ASME B16.20 standards. It is also deemed crucial for graphite fillers. This sophisticated profile is ideally suited for both raised and flat-faced flanges. The external guide ring offers added radial strength to avert gasket blowout and functions as a reliable compression stop. Typically crafted from carbon steel—either painted or zinc plated for corrosion resistance—it can also be created from alloys for high-temperature and severe medium applications, ensuring durability and longevity. This gasket truly sets the benchmark for quality and reliability in demanding conditions.
