Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
This exemplary spiral wound gasket boasts a robust construction with both solid outer and inner rings. An additional inner ring is meticulously integrated to significantly boost the gasket's performance, while the external guide ring ensures precise centering on the flange face. The inner ring plays a critical role in preventing implosion during installation, safeguarding the sealing element from extreme conditions, filling any voids to avert flange erosion, and minimizing failure risks. Adhering to the DIN 2699 standard, which mandates inner rings in all spiral wound gaskets, and the ASME B16.20 standards, it is indispensable for gaskets with PTFE and highly recommended for graphite fillers. This sophisticated profile is ideally suited for raised and flat-faced flanges. The external ring delivers enhanced radial strength to avert blowouts and functions as an essential compression stop. Typically crafted from painted or zinc-plated carbon steel to resist corrosion, the outer ring can also be fashioned from specialized alloys to withstand higher temperatures and challenging mediums.
