70/30 Cu-Ni use in sour environment 1

[tolga11]

hello all,

I would like to ask the suitability of using 70/30 Cu-Ni piping in the sour environment and in the applications below.

thank you.




COOLING WATER, OPEN DRAINS (OILY),
CHEMICAL DRAINS, TREATED SEA WATER,
UTILITY WATER, OILY WATER,
BRACKISH WATER , WASH WATER,
FIRE WATER (BRACKISH)-BELOW GROUND DUTIES ONLY PRODUCED WATER
FIRE FIGHTING FOAM - BELOW GROUND DUTIES ONLY PROCESS CONDENSATE
BRINE WATER, EFFLUENT WATER,
DEDICATED DRAINS, WASTE WATER,
OILY BRINE,

All I have ever seen used for these applications is 90/10 Cu-Ni. Is this for offshore use?

you may find the data you need at the following:

I hope it helps.

this is for off shore use.

I scanned the link you provided, it helped me lot thanks.
I also need the wall thickness values for 1/2, 3/4, 1, 1 1/2 and 2 inch pipes for these applications.

You're asking WAY too much of a free forum.

If you need to calculate wall thicknesses and do not know how, then I very strongly suggest that you find an engineer experienced in this field, hire them, and pay them appropriate engineering fees.

For detailed design and calculations, you are on your own.
Good luck!
