SPIRAL WOUND GASKET
PRODUCT DESCRIPTION:
Product Type:XINSEN-SD
Outstanding Features:
Introducing an impeccably engineered spiral wound gasket, designed with a robust solid outer and inner ring. Notably, an additional inner ring is meticulously incorporated to amplify gasket performance. This enhancement ensures optimal centering on the flange face through a precision external guide ring. The inner ring is ingeniously added to avert potential implosion into the pipe during installation, shield the sealing element from severe temperatures and diverse mediums, fill the gap between flanges to forestall flange erosion, and minimize failure risks. Constructed typically from the same alloy as the winding, the inner ring meets the stringent DIN 2699 standard (German), mandating its inclusion in all spiral wound gaskets. Compliance with ASME B16.20 standards necessitates inner rings for gaskets with PTFE filler, and they are deemed crucial for graphite fillers. This profile is predominantly applied in raised and flat-faced flanges. Further, the external ring contributes unmatched radial strength, preventing blowouts and serving as a compression stop. The outer ring is usually fabricated from carbon steel, painted or zinc-plated to resist corrosion, yet can be crafted from alloys for elevated temperature and demanding medium applications.
