G 407 (M)
Conversion of Gas Pipelines made of Steel Pipes for the Distribution of Hydrogen-containing High-Methane Gases and Hydrogen up to 16 bar Operating Pressure
Umstellung von Gasleitungen aus Stahlrohren bis 16 bar Betriebsdruck für die Verteilung von wasserstoffhaltigen methanreichen Gasen und Wasserstoff
Brief description
This DVGW Code of Practice G 407 applies to the conversion of gas pipes made of steel pipes to hydrogen-containing methane-rich gases (2nd gas family) or hydrogen (5th gas family) in accordance with DVGW Code of Practice G 260 up to 16 bar operating pressure and concludes with the main shut-off device (HAE), the transition point to DVGW G 600 (A) or G 614-1 (A) (with the additions listed in DVGW Code of Practice G 655). DVGW Code of Practice G 407 provides guidance for a systematic approach to the assessment and conversion of existing gas distribution networks to operation with hydrogen-containing, methane-rich gases and hydrogen. In particular, technical aspects and the procedure for determining the material-mechanical suitability of a gas pipeline are described.
