Pipes and tubes are the primary products in the metal industry. Pipes are long, hollow, and circular-shaped cylinders helpful to transfer fluids (liquid or gaseous) from one pipeline to another. On the other hand, tubes are long and hollow cylinders usable in structural and mechanical applications.

Hastelloy C22 is a nickel-chromium-molybdenum superalloy. It is resistant to reducing environments and oxidizing agents. It also contains a small amount of tungsten(2.5% to 3.0%), which provides lower thermal expansions and additional corrosion resistance in high-temperature areas.

Hastelloy C22 enhances the strength, stability, and durability of the pipes and tubes in industrial premises. The nickel and molybdenum elements make the pipes and tubes stronger against reducing agents, while its chromium component enhances these pipes and tubes against oxidizing agents.

Mangalam Metal Corporation stocks and supplies an exclusive range of Hastelloy C22 Pipes and Tubes to our clients across the globe. We use high-quality raw materials to manufacture Hastelloy products to meet national and international demands.


Pipes and Tubes are highly versatile and helpful to carry out numerous engineering applications. In the metal industry, we coin the terms pipes and tubes interchangeably. However, they are very different!

Pipes are long-hollow round-shaped cylinders helpful to transfers flowing fluids from one pipe to another. The fluids include gases, pellets, powders, liquid, etc. These pipes are connected to pipe fittings like flanges, valves, bolts, etc., using welding, soldering, or forging methods.

On the other hand, Tubes are long-hollow rods helpful to support or install in structural applications, including pressure equipment, machinery parts, and instrumentation systems. Usually, they are available in round, rectangular, oval, and square shapes. Also, its outer diameter is not more than 5-inches.

  • Hastelloy C22 is a corrosion-resistant alloy. Thus, it provides durability and strength in extreme temperature areas.
  • Hastelloy C22 contains higher tungsten and ferrous content, which enhances the toughness of the pipes and tubes during the fabrication process.
  • Hastelloy C22 exhibits oxidation and carbonization resistance in high-temperature areas. During the heating process, it eliminates the risk of losing carbon components and maintains the strength and integrity of the pipes and tubes.
  • Hastelloy C22 coating assures long endurance. However, it is expensive compared with other alloys, but it provides better corrosion resistance in oxidizing corrosion than C4, C276, and 625 alloys.
  • Hastelloy C22 also provides corrosion resistance in acidic environments. Thus, it offers resistance to the pipes and tubes installed in seawater and high-chloride environments. 
  • Hastelloy C22 alloys enhance the fabrication and weldability properties. We can install them in the industrial premises by standard welding, soldering, or forging methods.
Markings and Packing

Product packaging serves to protect the products inside. Mangalam Metal Corporation effectively ensures all the products are deliverable to our clients securely. In the case of exports, we follow all international standard protocols of packaging.

Often, we export them in wooden cases. We mark our products with Grades, Lot Numbers, Size, Degree, and our Trademark. We also make custom markings on the products as per the requirements of our clients.
