According to ASTM B167, the Inconel 600 tube, which falls under the nickel alloy category can be supplied in any of the following conditions i.e. -  cold worked annealed, hot worked annealed, or they could be hot-finished.

Intended to be used for general corrosion resistance and heat resistant applications, the Inconel 600 seamless tubing is ideally considered for use in industries such as chemical and food processing equipment, paper mills, heat exchangers.In a chemical processing plant, the Inconel 600 seamless tube is one such alloy that is capable of exhibiting excellent behaviour. In fact, it is the balance of chemistry that sees to the alloys corrosion resistance properties.

Individually,  both chromium and nickel have excellent corrosion resistance properties, but with the unique combination in terms of chemistry makes the ASTM B167 UNS N06600 tube well suited to be used not only in oxidative conditions but also in those conditions where reductive reactions are prominent. Not forgetting to mention the thermal processing industry, the Inconel 600 tubing finds use in application where resistance to oxidation is required.

Further, this type of industries has furnace atmospheres prevalent. In such an atmosphere, the Alloy 600 tubing can thrive but not becoming susceptible to creep. In addition to this, the Alloy 600 tube is also seen in nitriding applications due to its resistance to nitrogen at high temperatures.

 

Always Remember

For Boilers, Heat Exchangers and Gas lines always use Inconel 600 seamless Tubing. Avoid welded tubes even its a cheaper option.

What is alloy 600 CDS tubing and why it is used in boilers?

The alloy 600 is a nickel chromium alloy that can operate in a high range of temperature. It could operate under cryogenic conditions as well as temperatures up to 2000 Fahrenheit. The CDS stands for Cold Drawn Seamless. So the alloy 600 CDS pipes are seamless and cold drawn. So they are dimensionally accurate with all the mechanical properties of the material to operate under undulating temperatures. This is the reason why they are used in high temperature services such as the boilers, heat exchangers, power generation plants and in super heater elements.
