Hi Folks,

We are currently working on GRE pipeline project. The line size is 24" and Design pressure is 25 barg.
The question I would like to raise is wether we can use API 15LR code or API 15HR.

As there is a size limitation of upto 16" in API 15LR, and pressure criteria of 34 barg and above in API 15HR, we are unable to choose the design code.

can u guys sugegst some way out...

Regards
Ben
