Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This spiral wound gasket is meticulously engineered with a robust solid outer and inner ring for superior durability. To ensure unmatched performance, an innovative inner ring has been strategically inserted, enhancing the gasket's capabilities. This external guide ring is adeptly designed to precisely center the gasket on the flange face, safeguarding it from potential disturbances. The inner ring plays a pivotal role in preventing the gasket from imploding into the pipe during installation, shielding the sealing element from extreme temperatures and aggressive mediums. It efficiently fills the void between flanges to prevent erosion, significantly reducing the likelihood of failure. Typically crafted from the same high-quality alloy as the winding, the inner ring complies with the DIN 2699 standard (German) and is a requisite for all spiral wound gaskets. It's essential for gaskets with PTFE filler as per ASME B16.20 standards and highly recommended for those with graphite fillers. This versatile profile is ideal for both raised and flat-faced flanges. Additionally, the external ring offers enhanced radial strength, preventing blowout and serving as a reliable compression stop. Often made of carbon steel, painted or zinc-plated to resist corrosion, the outer ring can also be customized with alloys for high-temperature and demanding medium applications.
