pipe maintenance

Hi all,

I live in Calif and my house was built in 1940's. One section of the my exterior gas pipe(about 4 ft) is not under cement, just under about 2, 3 inches of grass/dirt. it's got certain amount of rust. I was wondering if I bury it with cement, will it prevent it from further deteroriation and fix the problem once for all or will it only offer little help because it's already got rust?

thanks

I would only paint it with rustoleum paint

when ever you bury something you are also
sort of sealing in any moisture that would happen
to occur with the changes of temperature...

best to leave it exposed

You CANNOT bury a plain gas pipe under concrete under any circumstances. If it leaks it could create an explosive gas pocket, or force the leaking gas to a different location where it could create a very hazardous condition.
1. The gas line should be at least 12" below the surface.
2. It should be of an approved material, and if yours is rusted, it was not. (And even the "approved" steel pipe can be vulnerable to failure.)
3. All "uncoated" exposed surfaces must be primed and taped.
4. Under concrete the pipe is usually inside a sealed and vented "sleeve".
