Flanges are the circular-protruded rims helpful to connect pipes to form an overall piping system. After welding, flanges are the second most convenient method to join pipe fittings where dismantling and assembling of pipelines are frequent. They are highly versatile and available in various shapes and sizes.

Hastelloy C22 is a nickel-chromium-molybdenum superalloy. It exhibits good mechanical properties, which provide excellent resistance against corrosion and oxidation in high-temperature areas. Also, the Ni-Mo elements make the surfaces stronger against most reducing agents.

Hastelloy C22 ensures stability, durability, and toughness to these flanges in extreme environments. Hastelloy C22 also contains tungsten (3% approx.), which offers low thermal expansion against heat and pressures.

Mangalam Metal Corporation is one of the global leading distributors and suppliers of Hastelloy C22 Flanges across the globe. We use high-quality raw materials to manufacture flanges to meet national and international demands.

APPLICATIONS OF HASTELLOY C22 FLANGES

Flanges are highly flexible and provide good connectivity to the pipelines using various equipment and valves. A flanged joint constitutes three main components:

  • Flanges
  • Gaskets
  • Bolting

Flanges are available in various shapes and sizes. It requires a highly skilled individual to assemble or dismantle these flanges. Also, we need to undertake essential factors like scope of work, physical environment, installation procedures, piping materials, etc., before selecting these flanges and their coating alloy.

However, it is not advisable to use flange connections in the underground piping system, as they are prone to leakage and fire in the processing plants.

Following are some industries and their applications where you will find our Hastelloy C22 Flanges installed.

  • Pressure Vessels
  • Storage Tanks
  • Demethanizers
  • Depropanizers

KEY PROPERTIES OF HASTELLOY C22 FLANGES
  • Hastelloy C22 contains higher tungsten and ferrous content, enhancing the toughness of the flanges 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 flanges.
  • 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 these flanges installed in seawater and high-chloride environments. 
  • Hastelloy C22 alloys enhance the fabrication and weldability properties. We can install these flanges in the industrial premises by standard welding, soldering, or forging methods.
