Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the exceptional design and engineering of this spiral wound gasket, featuring a robust solid outer and inner ring. Enhanced with an inner ring, this gasket is engineered to optimize performance. The expertly inserted external guide ring ensures precise alignment on the flange face, enhancing your installation process. This strategically added inner ring safeguards against gasket implosion into pipes during installation, offers protection for the sealing element against extreme temperatures and harsh mediums, and fills the void between flanges to prevent flange erosion, significantly reducing failure risk. Constructed typically from the same alloy as the winding, it meets the DIN 2699 standard for all spiral wound gaskets and is essential for PTFE fillers per ASME B16.20 standards, with special consideration for graphite fillers. Ideally suited for raised and flat faced flanges, the external ring adds crucial radial strength to prevent blowout and functions as a reliable compression stop. The outer ring, often crafted from painted or zinc-plated carbon steel for corrosion resistance, can also be made from premium alloys for high-temperature and severe medium applications.
