Can anyone tell me if it's ok to route stainless steel tubing underground in direct contact with earth for instrumentation purposes? Or could you point me toward which standard I should be looking in? This is typical tubing used in instrumentation. 3/8"x20'x.032" ATP 304 304L

If you just direct bury it, you will have to dig it up to replace it, and you will replace it someday.

If you put it in a conduit, you can pull a replacement tube without digging.

I'm not seeing the virtue of direct burial, except maybe in a sandy desert.
