What should be used for anti-corrosion of the inner walls of pipes at temperatures above 150 degrees Celsius instead of cyanide-based compounds?
Thread Content
Dear all, what anti-corrosion coating should be used for carbon steel pipes handling 150-degree ammonia? We have been using cyanide-based coatings in the past, but the temperature is quite high this time, and such coatings cannot withstand such high temperatures. Please advise
A steel-lined PTFE version or one with PFA coating should be able to solve your corrosion problems; however, the cost will be higher than what you spent before!
It would likely need to be customized. Considering time and cost, it might not be suitable, but from a technical perspective, is there any simpler solution that could be used?

In terms of temperature resistance, PTFE can withstand 180 degrees, while PFA can handle 200 degrees; the specific value depends on your application conditions. There shouldn’t be any issues with the production time – if you have ready-made steel pipes available in your area, that’s fine. Contact me via station message
