Underground SS 304 or 316 tubing?
Underground SS 304 or 316 tubing?
(OP)
We are considering using SS tubing for high pressure Hydrogen underground. Will corrosion protection be needed?
Does anyone have experience with this application?
Thanks,
TRW

a) what is the pressure ? diameter ????
b) what is the distance ?
c) what type of soil -
dry / wet / what chemistry and
electrolytes ??????????????
d) any big power lines near ??????????
will this be part of a ground
(earth ) sustem picking up
destructive stray currents ???????
e) is operation steady state after reaching
equilibrium or does pressure fluctuate ???????????????????????????????????????????
IE filling hydrogen vehicles ?

Internal is no issue, even if there is water.
External could be a nightmare, considering the risk if there is a leak.

There are guidelines for the design and installation of above and underground hydrogen piping systems. New standards are also in development.
Consider NFPA 55 and the rules contained in ASME B31.3
http://ww
The Compressed Gas Association (CGA) also publishes recommended guidelines for hydrogen systems.
