Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing our cutting-edge spiral wound gasket, engineered with precision to deliver superior performance and reliability. This innovative gasket is meticulously designed with robust outer and inner rings that ensure stability and optimal sealing capabilities. Notably, an expertly inserted inner ring enhances the gasket's performance by preventing collapse into the piping system during installation, safeguarding the sealing element from extreme temperatures and aggressive mediums. This clever design effectively fills any voids between flanges, thereby preventing flange erosion and reducing the likelihood of failure. Crafted from the same high-quality alloy as the winding, the inner ring meets the stringent requirements set by the DIN 2699 standard. For gaskets utilizing PTFE fillers, inner rings are mandatory according to the ASME B16.20 standards, and are highly recommended for those with graphite fillers. Ideal for both raised and flat-faced flanges, these gaskets provide exceptional radial strength, courtesy of the external guide ring, which also prevents blowout and serves as a compression stop. Typically manufactured from painted or zinc-plated carbon steel to resist corrosion, the outer ring can also be composed of specialized alloys for applications requiring higher temperatures and more severe conditions.
