What are Inconel tube fittings?

Inconel tube fittings are also important parts of the modern piping systems, as they are used to join tubes safely and provide leak-free connection of the union in the critical cases. These fittings are made of Inconel, a superalloy that is made of nickel and chromium, which are able to resist corrosion, extreme temperatures, and oxidation. They are especially significant in those industries where durability, high pressure, and predictable performance under high temperature are priorities, like in aerospace, chemical processing, and power generation.
