Hastelloy C22 Seamless Pipe
Steel Pipe & Tubes has been a leading supplier of Inconel alloy piping solutions.
Hastelloy C22 Seamless Pipe
Hastelloy C22 Seamless Pipe is a tubular product manufactured without a welded seam, designed for critical service in the most aggressive industrial environments. Produced from the nickel-chromium-molybdenum-tungsten alloy UNS N06022, this pipe offers outstanding resistance to a wide range of corrosive media, including oxidizing acid chlorides, wet chlorine, and formic and acetic acids. Manufactured via extrusion or rotary piercing to the ASTM B622 standard, the seamless construction provides maximum pressure integrity and uniform strength, making it ideal for high-stress applications.
The unique combination of Chromium, Molybdenum, and Tungsten in Alloy C22 provides exceptional resistance to pitting, crevice corrosion, and stress-corrosion cracking. Unlike other nickel alloys, its high chromium content gives it superior resistance to oxidizing media, while the molybdenum and tungsten provide resistance to reducing media. This versatility makes Hastelloy C22 Seamless Pipe the premier choice for conveying highly corrosive chemicals in pharmaceutical reactors, flue gas desulfurization (FGD) systems, and specialized chemical processing plants where system reliability is paramount.

Frequently Asked Questions (FAQs)
The primary standard for the material and manufacturing of Hastelloy C22 seamless pipe is ASTM B622 (Specification for Seamless Nickel and Nickel-Cobalt Alloy Pipe and Tube).
Seamless pipe is formed from a solid billet and has no weld seam, giving it superior strength and pressure rating. Welded pipe is made from a flat plate that is rolled and welded, which can be more economical for larger diameters.
"Schedule" is a standard that indicates the wall thickness of a pipe. A higher schedule number means a thicker pipe wall, which can handle higher pressures.
C22 offers better overall corrosion resistance, particularly in highly oxidizing environments. C276 is a robust workhorse alloy, but C22 is specified when superior performance against pitting and crevice corrosion in complex streams is needed.
Yes, Hastelloy C22 has excellent weldability. It is typically welded using matching filler metals (ERNiCrMo-10) and standard welding processes like TIG (GTAW) and MIG (GMAW).
