Oxygen Pipeline and Piping Systems - Sixth edition
The scope of this publication is for metal oxygen pipelines, distribution piping systems, and gaseous oxygen piping on an air separation plant external to the coldbox. The scope is limited to gaseous oxygen with a temperature range between –22 °F and 400 °F (–30 °C and 200 °C), pressures up to 3000 psi (21 MPa), and a dew point of –22 °F (–30 °C) or less depending on local conditions.1, 2 Although it is possible to safely use oxygen at higher temperatures and/or pressures, such applications are beyond the scope of this publication. In these cases, additional materials testing and/or a risk assessment, as appropriate to the application, shall be undertaken.
