Product Description

Product Description

SPIRAL WOUND GASKET

DESCRIPTION:

Product Type:XINSEN-SD

Features:

This exceptional spiral wound gasket, designed with a robust solid outer and inner ring, features an inner ring skillfully inserted to elevate gasket performance. The addition of an external guide ring ensures precise centering on the flange face, effectively enhancing installation accuracy. The inner ring, crafted to avert the risk of gasket implosion into the pipe during installation, serves as a guardian protecting the sealing element from extreme temperatures and harsh mediums. It intelligently fills the void between flanges, safeguarding against flange erosion while mitigating the risk of failure. Typically constructed from the same alloy as the winding, the inner ring aligns with DIN 2699 standards and is vital for gaskets with PTFE and graphite fillers as per ASME B16.20 specifications. This versatile profile is ideally suited for raised and flat-faced flanges. Meanwhile, the external ring contributes remarkable radial strength, preventing gasket blowout and functioning as a reliable compression stop. Often manufactured from carbon steel, optionally painted or zinc-plated to prevent corrosion, the outer ring can also be produced from specialized alloys for high-temperature or severe medium applications.
