SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This advanced spiral wound gasket is engineered with a robust outer and inner ring. The inner ring is designed to enhance performance by preventing implosion into the pipe during installation, protecting the sealing element from extreme conditions, filling the void between flanges to prevent erosion, and reducing failure risk. Typically made of the same alloy as the winding, the DIN 2699 standard mandates inner rings for all spiral wound gaskets. ASME B16.20 standards require inner rings for PTFE fillers, and they are crucial for graphite fillers. Ideal for raised and flat-faced flanges, this profile's external guide ring centers the gasket accurately on the flange face, providing additional radial strength to prevent blowout and serving as a compression stop. The outer ring, often constructed from carbon steel and either painted or zinc-plated to prevent corrosion, can also be made from high-performance alloys for severe applications.
