Product Description
SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This spiral wound gasket is a marvel of engineering, featuring a robust solid outer and inner ring structure. An innovative inner ring is strategically inserted to significantly enhance gasket performance. Meanwhile, an external guide ring ensures precise centering on the flange face. The inclusion of the inner ring is pivotal; it prevents gasket implosion into the pipe during installation, shields the sealing element from harsh temperatures and aggressive mediums, and effectively fills the void between flanges to avert erosion, thereby minimizing failure risks. Typically crafted from the same alloy as the winding, the inner ring aligns with DIN 2699 standards, mandating its presence in all spiral wound gaskets. This is particularly crucial for gaskets with PTFE filler as per ASME B16.20 standards, and similarly significant for those with graphite fillers. This versatile profile is ideally suited for both raised and flat-faced flanges. The external ring not only offers additional radial strength to curb blowout but also functions as a compression stop. Often constructed from carbon steel, with options for painting or zinc plating to combat corrosion, the outer ring can also be made from alloys for applications involving higher temperatures or more aggressive mediums.
