I am using 800 psi helium overpressure to feed liquid nitrous oxide into a system. I need to find a pressure regulator that can be set for 800 psi and maintain this pressure for the entire cylinder without needing to be reset. I am currently using a typical one stage high pressure cylinder...
I need to insulate a steel tank that will contain hot gas and be immersed in water and be sujected to pressures of about 500 psi. I would like suggestions of what materials would be suitable for insulating the vessel.
Thank you
