You may want to take at the requirements for buried black steel gas line. I believe the sleeve for this has to be 10 mils thick with the joints wrapped with 10 mils of pvc tape and then sealed with the goo. And it's been a long time (1979) since I've dealt with plumbing so my numbers may be way off. Try your plumbing code for guidelines relative to protecting like piping.
