SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This meticulously engineered spiral wound gasket boasts a robust design featuring both a solid outer and inner ring. The addition of an inner ring is crucial; it significantly enhances the gasket's performance by ensuring precise centering on the flange face. This inner ring is strategically incorporated to prevent the gasket from imploding into the pipe during installation, offering superior protection to the sealing element against the ravages of extreme temperatures and harsh mediums. Moreover, it impeccably fills the void between flanges, effectively preventing flange erosion and drastically reducing the risk of failure. Typically crafted from the same durable alloy as the winding, the inner ring complies with the rigorous German DIN 2699 standard, which mandates its presence in all spiral wound gaskets. Particularly essential for gaskets with PTFE filler as per ASME B16.20 standards, the inner ring is also deemed highly beneficial for graphite fillers. This innovative profile is ideally suited for both raised and flat-faced flanges. Enhancing the gasket's durability, the external guide ring provides additional radial strength, averting gasket blowout while serving as a compression stop. Often constructed from carbon steel, treated with paint or zinc plating to resist corrosion, the outer ring can also be manufactured from specialized alloys to accommodate higher temperature and more severe medium applications.
