Title (German)
Wasserstoff-Pipelinesysteme
Brief description
The scope of this document is for metallic transmission and distribution piping systems carrying pure hydrogen and hydrogen mixtures, as shown in Diagram 1 of Appendix A. It is limited to gaseous products: • with a temperature range between –40°C (-40°F) and 175°C (347°F), • total pressures from 1MPa (150 psig) up to 21 MPa (3000 psig) or for stainless steels only partial H2 pressure higher than 0,2 MPa • concentration criteria defined in Appendix G.
