SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
Introducing the highly advanced DONHONSIL Premium Spiral Gasket, designed with a meticulously crafted solid outer and inner ring. The inclusion of an expertly inserted inner ring dramatically boosts gasket performance, ensuring precise centering on flange faces with its expertly engineered external guide ring. This design innovation eliminates the risk of gasket implosion during installation, safeguarding the sealing element from extreme conditions, and filling flange voids to prevent erosion. Constructed using the same high-quality alloy as the winding, these inner rings adhere to the rigorous DIN 2699 standard, as well as ASME B16.20 requirements for PTFE fillers. Considered essential for graphite fillers, this profile excels in both raised and flat faced flanges. The robust external ring enhances radial strength, acting as a fail-safe compression stop, thus preventing blowout. Crafted primarily from corrosion-resistant carbon steel, it is also available in specialty alloys for high-temperature, severe conditions, showcasing unparalleled versatility.
