"I used this to protect 15mm copper radiator piping that needed buried in cement. It is easy to cut to length, and passes over the copper pipe easily (make your pipe ends rounded/de-burred first). You can also cut the conduit lengthways with a sharp knife, so it can be slipped over the copper pipe in difficult to reach places"
"Used this pipe conduit to bury radiator pipes in concrete floor. Bent the copper to create one continuous piece in the concrete so there were no joins, slid the conduit straight over the pipe which can be a little tricky around bends but plenty of flex to allow this and the jobs a good'en! This product will stop the lime in the cement corroding the pipes and allows plenty of room for expansion. Easy solution to protecting pipe."
