SPIRAL WOUND GASKET
DESCRIPTION:
Product Type: XINSEN-SD
Features:
Introducing the exceptional spiral wound gasket, meticulously designed with robust outer and inner rings for superior durability. An additional inner ring has been expertly incorporated to significantly enhance gasket performance, alongside an external guide ring ensuring precise centering on the flange face. The inner ring serves as a crucial component, safeguarding against potential implosions into the pipe during installation, shielding the sealing element from extreme temperatures and various media, and filling voids between flanges to avert flange erosion, thereby minimizing failure risks. Crafted typically from the same high-grade alloy as the winding, the inner ring meets the stringent DIN 2699 (German) standards which mandate its inclusion in all spiral wound gaskets, and it is indispensable for gaskets with PTFE filler as per ASME B16.20 standards, and is vital for graphite fillers. This innovative profile is ideally suited for both raised and flat-faced flanges. The external ring not only provides additional radial strength to prevent gasket blowout but also functions as a compression stop. Often constructed from carbon steel, which is either painted or zinc-plated to resist corrosion, the outer ring is adaptable and can utilize alloys for applications demanding higher temperatures and more severe media.
