Hydrogen Cylinder Valve

Hydrogen Cylinder Valve

Hydrogen Cylinder Valve

Dear Readers
There are Compressed Hydrogen Cylinders manufactured based on ISO 11120 and their working pressure is 180 bar and test pressure 297 bar. The valve installed on them is equipped with rupture disc of which bursting pressure is 3360 psi. I would like to know is installing valve with rupture disc correct on hydrogen cylinders. when this rupture disc bursts the hydrogen will comes out with high pressure and is dangerous.
Thanks in advance for your help

RE: Hydrogen Cylinder Valve

The alternative is rupturing the cylinders. A safety relief valve should be installed on your piping, which vents to a safe area. But what about when the cylinder valve is closed during transport or storage?

RE: Hydrogen Cylinder Valve

Rupture disc outlet must be discharge to safe area at top of building or some other tank. We can not allow hydrogen in air directly.
