Incoloy 825 pipe is a corrosion-resistant alloy pipe made from a nickel-iron-chromium base with additions of molybdenum, copper, and titanium. It is especially effective in handling sulfuric acid, phosphoric acid, and seawater corrosion, making it ideal for chemical processing, marine, pollution control, and nuclear fuel applications. Chinese factories are among the largest global producers of Incoloy 825 pipes, offering seamless and welded options in compliance with ASTM B423 and other international standards. This article highlights leading factories, manufacturing capabilities, and technical specifications.
