Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This spiral wound gasket is expertly engineered with a robust solid outer and inner ring. Notably, an inner ring has been meticulously designed to amplify gasket performance, coupled with an external guide ring that ensures precise centering on the flange face. The inclusion of the inner ring is crucial as it prevents potential gasket implosion into the pipe during installation, shields the sealing element from extreme temperatures and aggressive mediums, fills voids between flanges to avert erosion, and minimizes the risk of failure. Crafted typically from the same alloy as the winding, the inner ring adheres to the DIN 2699 standard, mandating its presence in all spiral wound gaskets. For gaskets with PTFE filler, the ASME B16.20 standards specify the necessity of inner rings, which are also deemed essential for graphite fillers. This advanced profile is predominantly applied in raised and flat-faced flanges. The external ring not only delivers added radial strength to counter gasket blowout but also functions as a compression stop. Generally made from carbon steel—either painted or zinc-plated to ward off corrosion—the outer ring can also be manufactured from alloys to withstand higher temperatures and more challenging medium applications.
