Flexible Preinsulated Plastic Pert Pex District Heating Pipe Extrusion Production Line
Description of Flexible PU insulated pipes:
What is polyurethane foam PERT insulation pipe?
Polyurethane PERT insulation pipe is called flexible insulation pipe in international, Chinese standard name is II type heat-resistant polyethylene (PE-RTII) low-temperature direct buried heating pipe.
Product description:The Flexible PU-insulated pipes are manufactured continuous maufacturing line inclding carrier pipe extrusion line,PU foaming,solidifying,corrugated forming,and PE jacket covering these parts.
Advantages of Flexible PUinsulated pipes:
1.Substantial cost savings
2.Continuous production method enables long delivery lengths,less pipe ioints
3.Flexible pipes can insulated directly underground and demands smaller excavation
4.Excellent mechanical properties
5.Flexible pipes are easy to transport,handle and storage

PE Jacket insulation steel pipe
○Steel slag fall in pipe, when welding, can not be cleaned.
○The system often alarms, needs to be dedicated, can not be automated.
○Due to its own characteristics, heating water additives and environmental factors, steel pipelines are prone to rust and corrosion, pipe networks are easy to block, and their service life is low.
○Elbow production process is complicated, costly and inefficient
○It is a large amount of excavation and Complex construction work.
○Costly construction
PE-RTII insulation pipe
○PERT II Pipes Can Tolerate Temperatures of 110°C
○Pipeline smooth, no impurities, no pollution
○Heating companies can realize unattended, automated operation
○Low temperature heating
○ 60 °C supply water 45 °C backwater to meet the heating demand.
○The construction is simple and convenient, and the excavation amount is 40%
○ ---- Greatly reduce construction costs
Market Survey
