high Pressure pumping

high Pressure pumping

high Pressure pumping

(OP)
Got a challenge.  Need to lift approximately 700 gpm of water approximately 1,300 feet.  Looking at different options, intermediate booster pumps, etc.., but I am curios if anyone has experience in lifting water at such a high pressure.  Any tips on pumps, piping, etc.
 

RE: high Pressure pumping

Oh that's still ANSI#300.  For a minute I thought we were talking 1300 meters.  

Are we going up a hill or are you down in a well?  You can try doing it with one pump if you want, but not suction lift.

RE: high Pressure pumping

vodeni,

A piston or a piston diaphragm pump can do this easily. A piston pump will be the more economic option, if there are not many solids in the water. A positive displacement pump of that size (flow, not pressure) is not cheap but I think cheaper than working with various centrifugals in serial.

RE: high Pressure pumping

One centrifugal is all you need; and undoubtedly cheaper than pistons in initial cost and a whole lot cheaper for maintenance.

RE: high Pressure pumping

BigInch: If you can do it with just one centrifugal and with a good efficiency, I'll fully agree. Any PD pump is more expensive.

RE: high Pressure pumping

Ya.  1's no problem.

RE: high Pressure pumping

(OP)
Thank you all,
I was looking at a multistage centrifugal pump that can give me over 500 psi.  But I am a little bit concern about piping, I understand that ANSI #300 should cover it, but what kind of pipes and joints are rated for 550psi and not even thinking about air release valves, water hammer control, etc..

Someone suggested using flexible stainless steel pipe (I am not quite sure if that is a good solution).  In any case it would be great to run the entire length of a pipeline without separate booster station.

Thanks again
 

RE: high Pressure pumping

BigInch,

I suppose you are making reference to one centrifugal, but multistage pump?

RE: high Pressure pumping

vodeni,

Can't you send a (handmade) sketch of your pipeline layout? You are taling about air release valves. That sounds as if your pipeline goes up down.

RE: high Pressure pumping

I count a multistaged as one pump.

You can always use steel pipe and welded joints.  You can probably find GR Plastic pipe, HDPE, etc. that might work for that pressure.  Think I saw that Victalic even works to 300#.  Lots of options.

You only need intermediate booster stations if you run out of pressure from pressure drop in a long horizontal run and have to put in another pump, but that might be 40 miles away or something.  Depends on your pipeline profile.  If its all straight up, do it with one pump.

RE: high Pressure pumping

(OP)
The pipeline literally climbs up the hill, so as it goes up there will be slight changes in slope with possible peaks and short downturns.  I am not quite sure yet, I just got the job.  Looks to me that a 300 HP pump should do it, just need to find the pump to give me approx 700gpm@1,250 feet (I assume to use 10" pipe and have approximatly 20-30 feet of headloss.  

Someone mentioned HDPE pipe, can you really use them at such high pressures: over 500 psi.  My understanding is that ductile iron is not even rated over 350 psi.  I feel, if there is HDPE pipe rated for that kind of pressure thatwould be most cost-effective solution

Thanks again for your kind support

RE: high Pressure pumping

With a 10" straight pipe and a flow rate of 700 gpm your head loss due to friction should be only about 5-6 feet (water@20 °C and weldless steel pipe).  

RE: high Pressure pumping

Now I thought I just saw numbers like 1000 psi for that stuff for HDPE Driscopipe. Give um a call before you throw the baby out with the bath water.

RE: high Pressure pumping

DriscoPlex™ 5300 Climate Guard™ pipe, molded fittings and fabricated fittings are manufactured from
high-density, high molecular weight PE 3408 polyethylene compound that meets or exceeds ASTM D
3350 cell classification 345464C, and is listed by the Plastic Pipe Institute in PPI TR-4 with HDB ratings
of 1600 psi (11.04 MPa) at 73°F (23°C) and 800 psi (5.52 MPa) at 140°F (60°C).

Maybe.  What is a HDB rating?

RE: high Pressure pumping

(OP)
To make things complicated I just found out that the actual length of the pipeline is approximately 45,000 feet.  The client appears to want us to use 6" Flexsteel pipe, that would put additional Oh gosh! 700 psi needed.
Now my head is spinning

RE: high Pressure pumping

Well I told you I don't know what HDB ratings were all about.  Anyway I thought there was a Driscopipe that could do 1000 or more.  They were trying to get me to use it on an oilfield flowline once.  Maybe it was lower pressure than I remember now.  Sorry if its a red herring.

Now.  45000 feet .... horizontal ... I presume.

You can still do it with one pump if the diameter is right, the pipe material is strong enough and the pump has the pressure capacity.  1460 psig is no problem for steel pipe, or one pump.  Just needs more power.  You're nowhere near any limits I know of.

Unless you got a small budget.

RE: high Pressure pumping

Just a guess but I think a 6" steel pipe is the cheapest option as it is standard and there are plenty of possible suppliers. So, you need 700 GPM against approx. 1450 psi clean water? Pretty big pump. Around 700 HP with a PD pump. I do not know whether one (multistage) centrifugal still can do that.  

RE: high Pressure pumping

I'm beginning to feel like Tom Sawyer fence painter.  When are you going to believe me?   That's only 24,000 BBL/day.  Nowhere near any flow or pressure or power limits.  In fact you're right in the middle of this chart.  Limits are far away.

Sorry, nowhere near the middle.  Kinda down and to the left.

RE: high Pressure pumping

BigInch, I beleive you if you tell me that it's possible (and you did). I just wanted to bring up the other option as head increased quite a lot in the meantime. Tom Sawyer's fence painter was pretty smart, wasn't he?

RE: high Pressure pumping

Thanks, I'll take it you mean that as a compliment, but unfortunately he wasn't exactly what one would call smart, as Tom managed to get him painting that fence for free, while, as I recall, he went off fishing smile
