High Pressure Tanks

[sarahr]

I am trying to find a manufacturer of large high pressure tanks (they need to withstand pressures of up to 5000psi). The tank would probably need to be about 600ft3 (or about 4500 gallons). I've never had to purchase anything like this before, and i was curious if anyone had any recommendations of where i should look or who i should speak to. (i realize its going to be a special order item but i'm not really sure what company i should i even consider looking at).

thanks for any input!

sarahr....

Where will the "tanks" be installed ?

If the installed location is the uSA, you will want the "tanks" to be designed, inspected, tested and stamped in accordance with the ASME Boiler and Pressure Vessel Code. Outside of the USA, many companies specify thier "tanks" to the Pressure Equipment Directive (PED)

If they are to be designed to ASME BPVC and are to operate above 3000 psig, they will probably require certification to ASME Section VIII, Division 2.....This will be stated on the certification plate.

By the way, I would not use the terminology of "tanks" I would call these containers "pressure vessels"

What will be contained in the vessels, what size will the be and will you contain a liquid/gas that could be considered as "lethal?

My opinion only..

Here are two that we have used for high pressure vessel fabrication.

I have to ask, being the curious George that I am. What would you want to store at 5000 psi?

Watch your design. Keep the L/D ratio as large as possible to lower the overall cost.

To help StoneCold and maybe you we used 4 vessels we called bottles, manifolded, to store H2 at 6300 psig, These vessels were designed for 11,000 psig. The vessels are somewhere out west storing N2.

Guys:

What stookeyfpe has referred to and what sarahr seems to looking for is nothing more than the conventional, HP, compressed gas "tubes" - much like those used in the high pressure storage and distribution of Hydrogen, Helium, and other compressed gases. Often they are used to transport the gases (in "tube" trailers) and then deliver them to similar stationary units by using a "cascade" system of pressure delivery.

Up to the introduction of cryogenic tanks and delivery systems in the 1960's, this was the only method whereby one could transport and deliver "large", bulk quantities of gas - like Oxygen to hospitals. Now, of course, cryogenic methods are employed and liquified storage and delivery is the norm.

What was once the norm and conventional system is now a unique and little-known method.

Montemayor,
Checking my data on the "Rolling Pipe Line Trailers" their max pressure was 2640 psi. These were the 22" OD
cylinders. The seamless cylinders were 22" OD x 34' Lg with a .535" wall and hemispherical heads with a 15.536" dollar insert with nozzle on each end. I don't have any data for the older 9 5/8" cylinders but if my recall is still working I believe they do go to around 3600 psi for the inerts and less for the reactive variety.

In the early 60's we used gaseous H2 brought in by trailers with smaller bottles and it was around 3000 psi when hard piped to our manifold. We took a pressure drop of 2985 pounds to get to suction pressure of our Hypers. Like you mentioned cryogenics came in the mid 60's which was lot better for our operation.

I was being kinda conservitive in my approach based on the availability of an off the shelf bottle for 5000 PSI.
