Hydrogen Piping
Hydrogen Piping
(OP)
I am looking for info on hydrogen piping design. I know there are some different design considerations than there are for natural gas, crude, etc. If any one has any info please let me know.

RE: Hydrogen Piping
RE: Hydrogen Piping
We have just completed re installing a portion of H2 line in our Plant. The Piping material is carbon steel and the valves istalled are very high valve leak proof Tech. Becareful, when we tested the line using water, It was ok. However when we run Nitrogen test , it was leak every where. The valves need special maintenance to repair. If you need more information I can provide u with it. The line which we installed was 40 Kg/cm2 Presure and ambiant temperture.

The material is A53 Gr.B. I have to bring to your attention to the following requirement when ordering
1- Chemical cleaning is required after pipe fabrication if hydrogen is used in a sensitive process reaction. (If you want the procedure I can givre it to u later)
2- Testing of the line must be by air / Nitrogen !
3- The valve specification for this line is very important. If you want I can provide you with manufacturer name.
4- our operatin pressure as I have mentioned is 40 kg/cm2 , hence a 100% radiography is required for all welding (Tig weld) joints.
5- Be carefull of instrument / Analyzer sample points, it should be fitted perfect.
6- Good luck :)
