    I would think not

    but it wouldn't hurt to get the OK from the tube manufacture. Concrete is pourus, and I'll bet there are some small road map cracks where the acid could get to the tube.

    You don't have any splices do you! I'd worry about acid on a coupling of any sort.

    PEX is acid resistant

    They ship hydrocloric acid in polyethylene bottles. Polyethylene is chemically resistant to acids. If I had to pipe hydrocloric acid from point A to point B I would probably chose PEX tubing.
