Inconel 600 Tubes

What Are Inconel 600 Tubes?

Inconel 600 tubes are nickel-chromium alloys which are designed specifically to operate in high temperatures. These tubes are oxidation resistant and heat resistant as they are rich in both nickel and chromium. This chemical composition enables them to retain their structural stability up to temperatures as high as 2000F. Their resistance to corrosion makes them a natural selection in the face of corrosive machines such as condensers and heat exchangers, where the regular metals would easily wear out.

From a technical standpoint, Alloy 600 tubing is incredibly durable. It features a minimum tensile strength of 655 MPa and a yield strength of 315 MPa, meaning it can handle significant physical stress without failing. These tubes are also highly resistant to chloride-ion stress corrosion cracking and perform reliably in alkaline or sulfur-rich systems. Depending on your project requirements, you can find these tubes in sizes ranging from 1/8" to 8" OD, with wall thicknesses spanning Schedule 5 to Schedule 160. 

Whether to use seamless or welded tubing is a matter of choice and normally depends on the application and budget. Seamless Inconel 600 tubing is produced with no joints or seams that give the tubing maximum strength and the tightest tolerances in high pressure applications. Welded tubing is more economical, though also very reliable with most corrosive mediums, and may be manufactured in much longer lengths, up to 26 meters. Both versions are required in the industries as far as food processing and paper mills up to oil refineries and marine engineering. 

In specialized systems, we provide solutions of specific systems such as boiler tubes and exhaust tubing. The purpose of boiler tubes is to transfer fluids and gases under high pressure without losing their shape, whereas the purpose of our exhaust tubes is to transfer the hot and spent gases in the combustion chambers. These products are constructed to international standards whether you are looking to have your tubing galvanized, annealed or cut to a given length.

Inconel 600 Tube Applications

Inconel Alloy 600 tubes are valued for their high strength and excellent resistance to corrosion and heat. These properties make them essential components in several critical industrial applications:

Industrial Applications
  • Heaters: Used in high-temperature environments, Alloy 600 maintains its structural integrity and resists oxidation up to 2000°F (1093°C).
  • Bubble Towers: These tubes are utilized in chemical processing towers to manage corrosive compounds and alkaline systems.
  • Condensers for Fatty Acid Processing: The alloy's resistance to organic acids and its ability to withstand extreme friction without deforming make it ideal for condenser systems.
  • Evaporator Tubes: Specifically designed to handle the movement of fluids and gases under high pressure and temperature without dissociating.
