Huitt (From a letter dated March 7, 2001 in response to a project s need to select tubing Material for Oxygen Service .) In selecting a pipe or tubing Material for Gaseous Oxygen Service there are four basic criteria: % Oxygen in the gas, pressure, temperature and velocity. As you can see by Fig. 1, if the system operates below 200 psig at 200 F then carbon steel or stainless steel would be suitable Material at almost any velocity. However, above those markers velocity becomes an issue and the Material Selection narrows. Figure 1 Maximum velocity versus internal pressure for steel pipelines ( mole% or higher Oxygen ) (Griffith and Wallis, Journal of Heat Transfer, August 1961) If a system is operating in a range above the curve in Fig.
