DN16 to DN32 underground heating PE-RT tube

DN16 to DN32 underground heating PE-RT tube   1.Brief introduction of PE-RT underfloor heating pipe:   PE-RT is injected by imported high temperature MDPE raw material. As new modified underfloor heating pipe system, it has the advantage of: antilower temperature impact and higher antipressure..     2.The specification of PE-RT underfloor heating pipe:

  4.The production process of PE-RT heating pipe:   PE-RT granule------convey to hopper---store on hopper----transported----injected into shape -----cool down ----pull forwad-----cutting------inspection----storage   5.Fitting or accessories of PE-RT underfloor heating pipe:   A: The first is the fittings made out with all plastic which is injected into shape by the machine.. they can be  directly connected with the ppr pipe with melt machine..these fittings includes: socket, reduced socket,tee   B: The second type is the fittings made of plastic with brass/steel thread. one side is used to connect with the ppr pipe and the other side is used to connected with water meter,steel pipe,water tap and so on..     6.The connecting way of PE-RT pipe for underfloor heating :   A:clean the pe-rt and fittings   B:choose different models according to the size of pe-rt and fittings C:set the temperature to 260°C  D: make the right deepth markt on pipe and fittings, then insert them to the machine E: heat melting  pipe and fittings together when time is ok, do not rotate slightly  within 5 seconds     7. The characters and advantage of PE-RTpipe for underfloor heating: It has the advantage of light weight,anticorrosion,high working temperature as ordinary ppr pipe The coefficient of linear expansion is just 20% to 30% of ordinary ppr pipe Strengthen the pipe rigidity and reduce the density and quantity of the suppor clamps  Higher pressure rating and long time life using Better high temperature resistance, can be worked under 95 to 100 centigree.. Increasing about 20% the water flow rating on the same wall thickness Resolve the problem of oxygen permeability and keep the water clear without bacteria.. 8.
