Scope and purpose

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. It 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 lower depending on local conditions.1

This publication does not apply to the following processes:

- oxygen cylinder filling plants;

- medical oxygen piping installations

- coldbox internal piping;

- oxygen compressor units;

- liquid compressor units;

- bulk oxygen facilities (liquid or high pressure gas) at the customer's site up to the point where gas enters the distribution systems; or

- piping on specialized equipment and machines such as scarfing, jet piercing, etc.

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.

Some of the practices represent conservative compromises and not all situations are described. The designer is cautioned that this publication is not a complete design handbook and does not do away with the need for competent engineering judgment and interpretation. It is suggested that the user review any special problems or concerns with his oxygen supplier who should be able to provide advice and guidance.

Although the technical information provided in this publication is not intended to be mandatory, the word "shall" is frequently used. The use of "shall" implies a strong concern that the particular practice referenced be followed for safety reasons. The use of "should" implies that the referenced practice is commonly followed, but recognizes that other safe practices are sometimes utilized.

1 kPa and MPa shall indicate gauge pressure unless otherwise noted as (kPa, abs and MPa, abs) for absolute pressure or (kPa, differential or MPa, differential) for differential pressure. All kPa values are rounded off per CGA P-11, Metric Practice Guide for the Compressed Gas Industry [1].
