Insulate it from cold air? You put the pipe down so deep that you don't have to worry about it.

Protect from what? Obviously they should be protected from all anticipated hazards.

Toad,
You will have to explain what you are using the pipe for. As stated above, if it is a waterline, it should be buried deep enough to avoid freezing. If your ground has lots of rocks in it, you should provide a "buffer zone" of sand around the pipe to prevent the rocks from cutting into the pipe. Good luck.

I live in southern california, no freezing issues. and no rocks. I thought that hot water lines need a plastic sleeve on them when placed under ground.

I personally want to have the hott water pipes insulated with a simple peal and stick foamb insulation generaly sold in 6 foot leghts. And I would also like to have a plastic sleve over all of the new copper pipes. I beleve the plastic sleve can protect against acidic soil and general corrostion.

The problem is I have not figured out a way to install bolth plastic sleve and foamb on at the same time on one pipe.

It seems that the plastic sleve is not needed in this aplication. Because I have no particular knolage of any hazards in my soil.

Yes, didn't guess that you meant hot water.

From where to where are the lines to be run?
You can install them in conduit to protect from the soil.
Insulating underground is more difficult than just peel-and-stick.
But if the conduit can be kept dry, that would work.

If you run a hot water line inside a conduit, it will cause condensate due to the dirrerence in temps of the soil and hot water. Trying to insulate and sleeve with conduit will be a real chore. Good luck.
