Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the unparalleled engineering of our ASME B16.20 Standard Spiral Gasket with SS316 Inner Ring. This meticulously crafted gasket features a robust outer and inner ring structure, with the inner ring ingeniously inserted to significantly bolster performance. The external guide ring ensures precise alignment on the flange face, preventing any possible misplacement. The inner ring is purposefully incorporated to avert implosion into the pipe during installation, safeguarding the sealing element against extreme temperatures and various mediums. It also serves to fill the flange void, thus preventing erosion and reducing failure risks. Constructed from the same alloy as the winding, the inner ring embodies the DIN 2699 standard’s requirement for all spiral wound gaskets, particularly essential for gaskets using PTFE fillers as per ASME B16.20 standards, and strongly recommended for graphite fillers. Ideal for raised and flat-faced flange applications, this gasket includes an external ring that adds considerable radial strength to thwart gasket blowouts, while also functioning as a compression stop. Often manufactured from carbon steel with protective coatings to resist corrosion, the outer ring can also be composed of specialized alloys for high-temperature and severe media applications.
