Content of DVGW Guideline G 409
DVGW Guideline G 409 applies to steel gas pipelines with a design pressure greater than 16 bar with welded joints. It describes the procedure for converting a high pressure gas pipeline.
G 409 applies to the high pressure gas pipeline as the whole including pipe bends, reducers, tees, caps, welding stubs.
The existing gas infrastructure has a large potential for the transport of hydrogen. Hydrogen can either be transported in its pure form or mixed with the natural gas stream.
The basic prerequisite for the use of hydrogen in the existing gas infrastructure is the technical suitability of the system. Here, it is particularly important to consider the possible changes in requirements caused by hydrogen. In particular, the influence on the pipework material requires precise assessment and evaluation.
For this reason, DVGW Guideline G 409 has developed specifications for a systematic procedure for the assessment and conversion of existing high pressure gas pipelines for the operation with hydrogen. In particular, the technical aspects and the procedure for determining the suitability of a high pressure gas pipeline are described.
