In Australia & SE Asia lines for sea water are in Acrylonitrile Butadiene Styrene (ABS). Tyco (Eurapipe) manufature to DN 750 in rubber ring jointed or chemicallly (solvent) welded. The ABS is not the same product as listed in ANSI B 31.3. Its much tougher. Of course you would need to have a few lines to cater for your flow.
The beauty of this material is that you dont get corrosion on the inside or the outside. Its great for sea water , septic sewerage, slurries, acid sulfate soils, puire water (electronics & pharmaceuticals) etc. W ehave just commissioned a 100 million dollar sewage treatment plant up grade where there is no ductile iron. All ABS or spiral wound stainless steel. I forget to mention it is cost effective too!

Subject: [PipingDesign] Cement Lined Piping
We have experienced a lot of leaks on our sea water cooling system. The 56" CS pipe is cement lined and was commisisioned way back in 1985 (FBE was not yet popular at that time). Its about a few kilometer long and has a coouple of inspection port, bends and branches. Anyone has a suggestion on how to rehabilitate the pipe short of replacing it. Ive got only a 5 days window. Damn corrosion coupon is of little use. We're surviving using the Belzona product (more expensive that gold on a per pound basis) to currently fix the leaks.
