Copper pipes in concrete

[Bullbags]

Best advice for laying copper pipes in concrete please.
Need to move a radiator about 2 metres to allow new door access. Copper pipes in concrete and will need to dig channel to get them out of the way.
Many thanks.

lay them in a duct.

lay them in conduit.

lay them in denso tape.

 

[kevplumb]

or use plastic

Denso won`t give enough movement space It`s what gas fitters used in the old days for wrapping iron gas pipes. Carried a roll on their bike handlebars

do not wrap in denso, it dries out in concrete and aids the corrosion proccess. It is only designed for use in damp/moist enviroments.

I thought Denso tape was designed to make your hands go rusty.

I'd use Hep or Speedfit

You could also either feed it through conduit or stick some armaflex on to give you some play in the pipes incase your measurements are slightly off after you fill floor in.
