Webgiven below. Piping systems must be designed so that the process pressure of the gas will not exceed the MAWP of the pipe, tubing, or components. C.2-1 LOW-PRESSURE HYDROGEN (<275 PSIG) For all sizes from 0.25- to 1-in. OD stainless steel tubing, 0.035-in. wall thickness is acceptable. WebHydrogen has a higher diffusivity than helium, thus its optimum linear velocity is higher and can be used at a higher flow rate without adversely affecting efficiency. Specifically, under isothermal analysis conditions, the typical linear velocity for hydrogen is 40 cm/sec, which is twice the optimum linear velocity of helium at 20 cm/sec.
