SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
This spiral wound gasket boasts a robust outer and inner ring design, with an added inner ring to significantly enhance performance. The external guide ring ensures precise centering on the flange face. The inner ring serves multiple critical purposes: it prevents gasket collapse into the pipe during installation, shields the sealing element from extreme temperatures and aggressive mediums, fills the void between flanges to avert erosion, and minimizes the risk of failure. Crafted typically from the same alloy as the winding, the inner ring meets the stringent DIN 2699 standard requirements. According to ASME B16.20 standards, inner rings are mandatory for gaskets with PTFE fillers and highly recommended for those with graphite fillers. This versatile profile is ideally suited for raised and flat faced flanges. The external ring not only provides additional radial strength to prevent blowout but also acts as a compression limiter. Often manufactured from carbon steel that is either painted or zinc plated to resist corrosion, the outer ring can also be made from specialized alloys for high-temperature and severe medium applications.
