Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Introducing our exceptional spiral wound gasket, meticulously engineered with a robust outer and inner ring to ensure unparalleled performance. The strategically inserted inner ring is the key to elevated gasket efficiency, safeguarding against the risk of gasket implosion into the pipe during installation. This ingenious feature fortifies the sealing element from extreme temperatures and harsh mediums, while adeptly filling any voids between flanges to prevent flange erosion and diminish failure risks. Typically crafted from the same high-quality alloy as the winding, the inner ring complies with the prestigious DIN 2699 standard, mandating its inclusion in all spiral wound gaskets. In line with ASME B16.20 standards, inner rings are mandatory for gaskets with PTFE fillers and strongly recommended for graphite fillers. Designed for ultimate compatibility, this profile excels in both raised and flat faced flanges. The external guide ring adds another layer of radial strength, effectively thwarting gasket blowout and serving as a reliable compression stop. Often composed of durable carbon steel—either painted or zinc plated to resist corrosion—the outer ring can also be constructed from alloys to withstand higher temperatures and more challenging medium applications.
