Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This advanced spiral wound gasket is ingeniously designed with both a robust outer and a solid inner ring. The inner ring is strategically inserted to markedly enhance the gasket's performance and is adeptly paired with an external guide ring that ensures precise centering of the gasket on the flange face. The purpose of the inner ring is multifaceted: it prevents the potential implosion of the gasket into the pipe during installation, shields the sealing element from extreme temperatures and harsh mediums, occupies the void between flanges to avert flange erosion, and minimizes the chance of gasket failure. Constructed usually from the same alloy as the winding, the inner ring meets the rigorous DIN 2699 German standards, which mandate inner rings in all spiral wound gaskets. As per ASME B16.20 standards, inner rings are essential for gaskets with PTFE filler and are deemed vital for those with graphite fillers. This versatile profile is ideally suited for raised and flat-faced flanges. The external ring imparts additional radial strength, effectively preventing gasket blowout and serving as a compression limiter. Typically crafted from carbon steel and either painted or zinc-plated to resist corrosion, the outer ring can also be manufactured from various alloys designed to withstand higher temperatures and more demanding mediums. This ensures reliability and longevity in diverse application settings.
