Product Description

SPIRAL WOUND GASKET

Product Description

DESCRIPTION:

Product Type:XINSEN-SD

Features:

Introducing the Spiral Wound Gasket, a marvel in gasket technology, uniquely designed with a robust solid outer and inner ring. The inclusion of an additional inner ring amplifies the gasket's performance by ensuring precise positioning on the flange face and protecting against potential implosion during installation. This inner ring serves as a safeguard, shielding the sealing element from harsh temperatures and aggressive mediums. It effectively fills any gaps between flanges, thereby mitigating erosion risks and diminishing the possibility of gasket failure. Constructed generally from the same alloy as the winding, the inner ring adheres to the stringent DIN 2699 German standards, mandating its presence in all spiral wound gaskets. It's essential for gaskets with PTFE filler according to ASME B16.20 standards and holds substantial importance for those with graphite fillers. Typically employed in both raised and flat-faced flanges, the addition of an external guide ring bestows enhanced radial strength, thwarting blowouts and acting as a reliable compression stop. Often crafted from carbon steel—either painted or zinc-plated to resist corrosion—or available in durable alloys for high-temperature and rigorous medium applications, this gasket is your ultimate solution for ensuring a secure and reliable seal.
