what is the procedure and/ or code for installing refrigeration lineset in cement?
Answers:    I try everything else previously I would run line sets within concrete, But if you need to after run it in PVC pipe, and engender sure you use a large plenty size to accommodate the pipe wit the bends.
Since concrete is corrosive, I would install a pvc pipe as a conduit and after the concrete sets then would push the refrigerant procession through the conduit. This way if you ever have a problem with the strip it could be easily replaced.
