Gas Supply at High Flow and Low Pressure Design

Your question is pretty tough as asked.

Let me see how I 'm doing here.

You have a quantity of 5 (five) cylinders each at a volume of 6 cubic meters. The 5 cylinders are manifolded to a header with 3 outlets to support the three evaporators. Each evaporator has a capacity(?) of 150 l/min @15psi.

If this is correct then please indicate yea or nay. If not please correct.

If correct as I have stated please further clarify EXACTLY what you need to know.

I will just spit a random out now given the assumption that I am understanding you.

Try a 0-100 psi low flow pressure regulating valve compression fit to 1/4" diameter SS, teflon or PFA tubing.

Dear Sir,

Please check out diagram. there are five cylinders each having capacity of 6 cubic metre. This will work as my supply gas.

Evaporator are instrument which consumes N2 gas at 150 l/min @ 15 to 20 psi.( you can put inlet pressure upto 75 psi but you have to adjust inernal pressure of instrument upto 15 to 20 psi.This is my basic requirement.

Other tubings & Regulators are equipped in design by me for safety purpose of line pressure ( Regulator 1 will maintain line pressure upto 100 psi & regulator 2 will maintain pressure at inlet of evaporator- It is not mandatory to keep regulator)

I just want technical idea for tunbing ID & regulator sizing (as most of pressure regulators are high pressure/low flow regulators & we require low presure/ high flow regulator)

Please advise me for same.

If all you need is a regulator to meet those reqs then search GlobalSpec - our benefactor.

Otherwise I am not really seeing a question here.
