The answer depends on what the application is ... material thickness is not the most efficient method of containment if it corrodes faster than the alternative. Thickness of the pipe is generally due to the pressure of the fluid, material of the pipe due to temperature and chemistry.
In order to get the right answer you need to say what it is going to be used for: water, gas, high pressure, low pressure, etc.

I don't think I agree with the above advice to use type M copper pipe. It is my understanding that there are 3 grades of copper pipe. Type K is the thickest and is used for underground. Type L is a little thinner but commonly used inside homes and is described as being perfectly suitable for that purpose. Type M is the thinnest and should not be used for anything I am told. Check this carefully. I really believe using type M would be a big mistake.

What is the pipe for? If it is for water,galvanized, or copper wrapped with protective tape. Don't use black pipe for pot-table water. It will rust quickly. Black pipe is used for natural gas, wrapped in protective tape. There is also a PVC made for gas. it is sch 40, and is yellow in color.
Galvanized pipe is a last choice. PVC is a good choice. Don't use thin wall sprinkler pipe. Use heavier sch 40 PVC. Copper is a better choice. Use type M rigid copper tubing. It has to be sweat fitted (soldered), cuz' it is too thin to threaded. Wrap it in protective PVC tape for underground. There are brass fittings that adapt copper to any other threaded pipe, if this is the case.
Just keep in mind to use whats called di-electric fittings between dissimilar metals. Any hardware store has them. GOOD LUCK!

Depends upon the thickness of the pipe wall as that is where the time quotient for erosion gets played.
'Black Steel' is usually Cast iron, Galvanized is Tin/alloy coated, (More rust resistant) and Copper usually lasts quite a long time underground ...but is expensive.
Plastic works to.
Again depends upon pipewall thicknesses as thicker will usually (not always) last longer

Think plastics. Even gas lines are going to plastic now. Waterlines became plastics years ago. The only places using metal pipes commonly are places were people could damage plastic, like inside houses.
