Material selection for high-temperature oxygen pipelines
Thread Content
I would like to ask everyone: for high-temperature oxygen pipelines with temperatures of around 1000 degrees and an oxygen concentration of about 90%, what material is suitable for the sampling tubes, especially those that are up to 30 meters long? The pressure is slightly positive, less than 100 Pa.
Or those who are capable of carrying out this oxygen concentration measurement can contact me directly
As long as it can withstand such high temperatures, it’s fine; low pressure poses no problem
I want to use copper pipes, but copper is prohibited on site; stainless steel, on the other hand, might overheat
Refer to GB 50030-2013 Code for Design of Oxygen Stations, Chapter 11; the table for material selection of oxygen pipelines is as follows:
Thank you for your help. I have studied this standard; in my case, the main issue is that the temperature is too high, and if there are impurities present, it’s easy for things to catch fire.
Then you can only use pressure-resistant materials, such as INCONEL or Monel; however, the cost is very high. You might want to take a look at the European oxygen pipeline specification IGCDOC13/02/E
