| 2004 Process Piping (ASME B31.3) |
B31.3 covers requirements for process piping typically found in
petroleum refineries; chemical, pharmaceutical, textile, paper,
semiconductor, and cryogenic plants; and related processing plants and
terminals. It prescribes requirements for materials and components, design,
fabrication, assembly, erection, examination, inspection, and testing of
piping. |
| Hydrogen Piping Systems at Consumer Sites
(CGA Publication G5.4) |
G5.4 covers materials and components selection to help guide installation of safe and effective hydrogen supply systems at consumer's sites. |
| Hydrogen Vent Systems (CGA Publication G5.5) |
G5.5 provides design guidelines for hydrogen vent systems for gaseous and liquid hydrogen installations at consumer sites, and provides recommendations for their safe operation. |
| Hydrogen Pipeline Systems (CGA Publication G5.6) |
This is a joint European Industrial Gases Association (EIGA)/CGA international harmonized standard on metallic transmission and distribution piping systems carrying pure hydrogen and hydrogen mixtures. It is limited to gaseous products with a temperature range between –40 °C and 175 °C (–40 °F and 347 °F); total pressures from 1 MPa to 21 MPa (150 psig to 3000 psig); and defined concentration criteria. |
