corrosion protection buried carbon steel pipe
(OP)
I am looking for help in protecting a 6' carbon steel
buried pipe against soil contamination, alkalinity,
acidity... whatever may be a problem. Would a bituminous
coating, galvanized and then an epoxy coating, or
some other sacridicial or cathodic protection be best?

click on course S110
download chapter 8 and look at the other info. This has charts that you can use to determine life using various coatings.

Are you putting 6 foot diamter carbon steel pipe in the ground or just 6 feet long smaller dia. pipe? otherwise...
Helps to know service temperature and chemical service inside of pipe first. Certain laws need to be complied with if this pipe is used to transport hazardous fluids beyond the boundary of your immediate facility on to/across public lands or if the pipeline is near a waterway. Save yourself the future liability.
Assuming your pipe is under 100 F most tape wrap works. A bituminous coating/tape can be very good. Hardly anything can coat over a bituminous coating/tape. Really don't need anything.
Cathodic protection designed by a properly educated and certified individual using impressed current or buried anodes will solve your problem if it is not too unusual.
A pipe inside a pipe is a good practice if this is a short section. You have built in leak detection ability.

Buried stainless steel can have its own problem if you are near high salinity water or other industrial contaminates.
