Make sure they are in good working condition.

Milling cutter

Make sure that it is in good working condition.

Make sure the blades are sharp enough.

Heating plate

Make sure the Teflon surface is free from damage.

Use a digital thermometer to check that the temperature reached corresponds to the temperature value set.


Test by doing experimental welding before use.


The CRDH is an on-site welding machine equipped with a heating element for butt-welding of pipes and/or fittings made of Polyethylene (PE), Polypropylene (PP) and other thermoplastic materials intended for carrying combustible gas, water and other fluids under pressure.

The CRDHcan weld PE100 with the “Dual Pressure” method.

The use of this welding machine is only allowed to trained staff having the qualifications required by the regulations in force.
