Hastelloy C22 Slip-On Flanges

Hastelloy C22 Slip-On Flanges are a type of piping component known for their exceptional resistance to general corrosion, pitting, and crevice corrosion across a wide range of aggressive media. These flanges easily slide over the pipe before welding, offering a lower initial cost and simpler alignment compared to other types. Hastelloy C22, an advanced nickel-chromium-molybdenum-tungsten alloy, is particularly valuable in chemical processing, pollution control, and pharmaceutical industries where exposure to strong oxidizers and reducing agents is common. Zeron Fasteners specializes in manufacturing and supplying these high-performance nickel alloy flanges to precise industry specifications.
