SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This premium spiral wound gasket boasts a robust outer and inner ring, with an inserted inner ring engineered to boost gasket performance. This innovative design allows for precise centering on the flange face, preventing any chance of the gasket collapsing into the pipe during installation. The inner ring shields the sealing element from extreme temperatures and harsh mediums, while filling the void between flanges to avert flange erosion and reduce failure risks. Typically, the inner ring is composed of the same alloy as the winding, adhering to the DIN 2699 German standard which mandates inner rings in all spiral wound gaskets. For gaskets with PTFE fillers, inner rings are required by ASME B16.20 standards and are deemed crucial for graphite fillers. Designed for both raised and flat-faced flanges, the external guide ring not only adds radial strength to prevent blowouts but also functions as a compression stop. While often crafted from corrosion-resistant painted or zinc-plated carbon steel, the outer ring can be made from various alloys to withstand higher temperatures and more severe applications.
