[G-4.4] Oxygen Pipeline and Piping Systems



Abstract:

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.

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.
