Sea Water Intake Lines
(OP)
hi all, i'm mechanical engineer at bp operation in tangguh LNG, papua. i wanna ask a question about sea water intake line material, is it safe if we are using the GRE pipe,or I should use a super duplex material, and does anybody has an information about the price of super duplex material, thx

What diameter, length and pressure are you dealing with?

In my experience 30°C is the limit for the application of Superduplex (PREN >40) in seawater.

It was not a lucky guess but just a simple suggestion based on the assumption that if the service is a Sea Water Intake Lines then the operating temperature should be quite "low"...
and as i said it was just a suggestion not a material selection report..
have a nice and lucky day

My point was: a recommendation without knowing the service conditions is a lucky shot. Tangguh is in tropical waters and will be very close to the generally adopted limit for super duplex. In all probability, the seawater may, on occasion, exceed 30 deg C.
Best to get complete data before making firm recommendations.

Experience is something that is not possible to teach.. You're right, i didn't think that in some areas of the world the seawater temperature can reach that values...
thanks for your help
all the best
