Bingham Willamette Pump curve 1

[MIANCH]

Hi ,
i'm looking Bingham Willamette pump curve, these are cargo loading pumps purchase by Esso international and installed in Libya many years ago. our company data system don't have pump curve and specific documents, can anyone help to find out these documents.
Pump Serial No. 240647/8
HST
Size: 24 X 30 X 30
Discharge head 170 ft
speed 880 rmp.
Thanks for your cooperation.

Have you tried the SULZER MANUAL located here ?

The mid-eastern information thieves have locked up all other copies except, of course the one one that they want to sell to you

MJCronin,
Link is not opening, can you from your resources and attach here.
Thanks

 

[MJCronin]

The link opens for me ....

You cannot read the text because the thieves want you to pay.

But the documents exist under the SULZER brand ...

Here is a different group of thieves

and another ...

http://media44.club/download/books.php?Sulzer+Bingham+Pump+Manuals

ESSO installed the pumps ?...... How old are they ?

You state that these pumps are "HST" series but that seems to be yet another error .... Do you mean "HSB" ?

Is this your pump ?

Whatever you do, please make sure that you just drop things when you get the information that you want ..

Never follow through, and never leave enough information for others to benefit

MJCronin,
Can sulzer provide me required information because these pumps were purchased in 1960s.
Thanks

MIANCH, why don't YOU ask Sulzer?

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)

 

[LittleInch]

Well if these pumps are 60 years old I don't think they will still be running like they used to when first built.

Can't you just test them in situ?

Sulzer may have the data as you have the serial no, but you might have to wait a while as they are probably archived somewhere.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

 

[MIANCH]

Definitely I will ask sulzer, we are upgrading the metering battery and some piping, contractor asked for pump curve for piping stress analysis. Asking in this forum always have very good information and right answer always.

 

[Artisi]

How will the pump curve assist in pipe stress analysis?
After operating for 60 years you would expect to know the flowrate and head - - - wouldn't you?

[MIANCH]

Artisi, can you elaborate further, if pump data is not useful then how contractor perform stress analysis.

 

[LittleInch]

Because stress in pipes is not really caused by fluid flow, only pressure and mainly temperature changes.

I have no idea why a piping stress person wants a pump curve. Have you asked them why as opposed to just going away and trying to find it? Always ask why someone wants information in a nice way. Then you might be able to supply it directly if it's not immediately to hand.

If you have to assume a max pressure at no flow, use 10 or 15% above it's current duty point.

[saplanti]

Probably, the contractor is looking for the allowable forces and moments on the pump flange. The contractor, I guess, assume that they can find it in the same document. Other than that there might be some extension of piping to consider in the layout, who knows?

I would suggest OP to ask contractor what exactly they need for the job, and divert the question on to Sulzer.

Some cases the drawing or maintenance instructions might be hidden in the client’s drawers, and none knows about the location of it other than the maintenance person in the plant

This us in Libya. Probably got destroyed in the last few years....

I draw the line at looking for drawings in the client's drawers.

 

[MIANCH]

Dear Sirs,
Yes project is in Libya, Ship loading pipeline is 48" and corroded. 1 km long portion need to replaced. contractor is local and have not much qualified and experienced staff. Pump documents are not available. I sent email to Sulzer but no reply received yet. contractor performed stress analysis and our piping engineer will review it.

 

[1503-44]

Why look for allowable loads on pump flanges? Those are always unreasonably low anyway. Just assume something less than 200 lbs for Fx,y,zand 200 ft lbs for Mx,y,z, then try to make the pipe stress loads on it as near zero as possible and get on with it.

If you are not reducing pipe diameter, or changing design pressure or flow rates, ask for the newest model of the same pump and get some new drawings for it. If not, you're kind of stuck with what you have there in front of you. Take pictures and measurements.

 

[Artisi]

If replacing corroded pipe with new pipe without any changes to size, length, flow or pressure- what is your concern?

[Artisi]

1503-44 what would depend entirely whose drawers you were looking into and why

[MIANCH]

Artisi, you are right but this condition is added in scope of work and my responsibility to comply with scope of work. Thank you for your good advice.

What a damned mess !! ..... This is an institutional problem, not an engineering one !!
