carbon steel piping with cement guniting
(OP)
Does anybody know of any probblems caused with internal corrosion on these pipes at all? I am thinking of using these pipes in cooling water.

And yes I know of problems, especially in service water or feedwater systems. Doesn't mean that carbon steel isn't used though. It just argues for a good erosion/corrosion program (at least if you're in the nuclear industry and such things are justifiable.)

cement mortar lining, on interior and exterior of pipes is used to protect the steel

According to US Army Corps of Engineers, for cooling water pipe less than 80 mm, use seamless Copper tubing type K, solder joint ASTM B88M. For 80 mm and larger, use seamless Black Steel, ASTM A53.
In my experience, for Black Steel pipe A53 larger than 80 mm, if exposed use standard schedule (schedule 40) and if embedded use extra heavy schedule (schedule 80).

1. Underground Service : RTR Pipes
2. Large bore above ground : Carbon Steel Pipes
3. Small Bore above ground : Carbol Steel piping with internal fusion bonded epoxy coating.
Yes for sure, there is a problem of corrosion. Usually corrosion inhibitors will be added for Cooling water services. Choice of selecting a higher schedule piping is also advisable.
