Oxygen Pipeline and Piping Systems
Oxygen pipeline systems developed over many decades in the various countries of Europe, North America, and in other geographies have shown good and comparable safety records, although company practices show many differences in design and operations. Some national authorities have also introduced legislation that is mandatory for the operators in those countries.
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 –30 °C and 200 °C (–22 °F and 400 °F), pressures up to 21 MPa (3000 psi) and a dew point of –30 °C (–22 °F) or less depending on local conditions.
The purpose of this publication is to further the understanding of those engaged in the safe design, operation, and maintenance of gaseous oxygen transmission and distribution systems. It is not intended to be a mandatory standard or code.
