SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
Marvel at the engineering excellence of this spiral wound gasket, featuring a robust solid outer and inner ring. An expertly inserted inner ring amplifies its performance, precisely centering the gasket on the flange face with a guiding external ring. This inner ring, crafted to prevent the dreaded implosion into pipes, shields the sealing element against extreme temperatures and aggressive mediums. It seamlessly fills the void between flanges, thwarting erosion and minimizing failure risks. Typically, the inner ring matches the alloy of the winding, complying with the German DIN 2699 standard, which mandates inner rings in all spiral wound gaskets. It's crucial for gaskets with PTFE filler as per ASME B16.20 standards and significant for those with graphite fillers. Ideally suited for raised and flat-faced flanges, the external ring elevates radial strength, preventing blowouts and acting as a compression stop. Generally constructed from carbon steel, either painted or zinc-plated to resist corrosion, outer rings can also be formed from high-temperature alloys for the most demanding applications.
