SPIRAL WOUND GASKET
DESCRIPTION:
Product Type:XINSEN-SD
Features:
Crafted with precision, this spiral wound gasket by Ningbo Dongheng Sealing Co., Ltd. is designed to deliver unparalleled sealing capability in extreme environments. Equipped with both solid outer and inner rings, this gasket goes a step further with an inserted inner ring that significantly boosts gasket performance. The external guide ring ensures precise centering on the flange face, while the inner ring wards off the risk of gasket implosion during installation. It also fortifies against harsh temperatures and aggressive mediums, seals the void between flanges to avert erosion, and minimizes failure risks. Adhering to stringent standards, the inner ring, constructed from the same alloy as the winding, aligns with DIN 2699 specifications and ASME B16.20 standards, making it essential for PTFE fillers and highly recommended for graphite fillers. Ideal for raised and flat-faced flanges, the external ring offers robust radial strength to prevent blowout and serves as a compression stop. Primarily made of carbon steel with options for corrosion-resistant coatings or high-temperature alloys, the outer ring is tailored for demanding applications.
