Product Description

SPIRAL WOUND GASKET

Product Type:XINSEN-SD
Features:
Discover the exceptional capabilities of our spiral wound gasket, ingeniously crafted with a robust outer and inner ring. The addition of an inserted inner ring significantly elevates the gasket's performance, providing superb protection and ensuring precise centering on the flange face with an external guide ring. This innovative inner ring design prevents implosion into the pipe during installation, shields the sealing element against extreme temperatures and harsh media, and meticulously fills the void between flanges to avert erosion. Furthermore, it substantially mitigates failure risks. Typically composed of the same quality alloy as the winding, the inner ring meets the DIN 2699 German standard, which mandates inner rings in all spiral wound gaskets. In accordance with ASME B16.20 standards, inner rings are crucial for gaskets with PTFE filler and highly recommended for those with graphite fillers. Perfectly suited for both raised and flat-faced flanges, the external ring enhances radial strength to thwart gasket blowout while serving as a compression stop. Generally crafted from corrosion-resistant painted or zinc-plated carbon steel, or specialized alloys for high-temperature and demanding applications, the outer ring offers unparalleled durability and performance.
