Inconel tube

Inconel tube
What is Inconel tube ?

Inconel material is well suited for extreme environments as they can withstand oxidation and corrosion.This is especially true when the inconel tubes are subjected to heat and pressure.On heating, the tubes form a stable and thick passivating layer on the surface, which protects the material from further attack.

Inconel can retain its strength for a wide temperature range.This is why the inconel hypodermic tubings are preferred for high temperature applications.Due to its high strength and hardness, it can get difficult to fabricate or machine Inconel.

Thus, traditional cold forming techniques should not be used to machine the tubes as they have a high work hardening rate.The thin wall Inconel tubing can display good resistance to chloride pitting and fatigue stress.They also possess high creep rupture strength and oxalic resistance.

What gas is used in Inconel tubing welding?

Argon is the most commonly used shielding gas for welding inconel welded tubes.Sometimes, an argon-hydrogen mixture might also be used, based on specific welding requirements.

This is applicable for both GTAW and GMAW welding techniques.

What are 6 application of Inconel square tubing ?
  • Inconel square tubing can be used as an exhaust system and engine components in the aerospace industry.
  • They are found in chemical processing plants for constructing reactors, heat exchangers, etc.
  • Inconel makes up the components and tubes that transport/process hydrocarbons in the petrochemical industry.
  • The material is often used in elevated temperature applications including heat exchangers, power generators, HVAC systems, etc.
  • The square tubes are also found as rector components, fuel handling systems, etc., in nuclear power plants.
  • They are made for marine and offshore applications.
What are the limitations of Inconel tube?
  • Inconel is quite expensive compared to standard stainless or carbon steel grades.Hence, they should only be used for critical applications where no cheaper substitutes are available.
  • Inconel tubing is tough and has high work hardening rate, which is why it is tough to machine them.
  • The material has a lower thermal conductivity and they can become brittle at extremely low temperature conditions.
  • They have a relatively high coefficient of thermal expansion that can cause dimensional changes when heated or cooled.
  • Due to high cost, Inconel has limited availability.This can increase the lead time of the project.
