(Table is made according to EN ISO 15875 :2003)

Those pipe has not any preventing layer against oxygen diffusion, therefore in the heating network should be prevented those parts, which are capable for corrosion (separation with heat-changer, additive – inhibitor – in the heating system, application of non-corrode materials, etc.)

The cross-linked polyethylene pipe can be directly laid into concrete and is applicable for all kind of heating system specified in Standard of MSZ EN 1264 – 1 : 1999.

By storage, transport and install the pipe should be prevented from any damaging. Installation of damaged and dirty pipes is forbidden!

The pipe must not be broken by installation! The heating of the pipe by flame is forbidden. (If it is needed just by hot water.)

By installation under plaster or out of the wall a protective pipe is necessary because of thermal expansion. Protective pipe should be water-proof.

By longer pipe sections (which is not laid in concrete) a compensational curve is necessary because of length changing. ( U Z )

Pipes can be equally bounded by disengaged – clamping, otherwise by express junction, not releasable moulded metal bind. (The supplementary control and drive in of binding should be assured.), (Threaded bindings must not be concreted)

If necessary for lengthening of pipe a stamped binding is applicable. In this case the pipe should be supported by a supporting sleeve from inside.

The heating system should be planned by a responsible designer and according to the plans should be completed and put in working by the guidance and control of a qualified technician.
