District Heating Pert / PPR Rigid Pre-Insulation Pipe Making Machine
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.
One-step pert flexible insulation pipe production line process flow:
Pipe unwinding - unwinding traction - V-shaped wheel conveying - track feeding - encapsulation and film coating - Pouring foaming - foam curing -PE layer O-shaped extrusion - Vacuum suction coating - spray cooling - winding
Advantages of the flexible pre-insulated pipe production line:
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
Compare between PE-RTII insulation pipe and Ordinary insulation pipe

Meticulously Designed for PERT: Every component, from the extruder to the cooling system, is
custom-engineered to meet the unique demands of PERT insulation
pipe production, guaranteeing superior quality.
Low Heat Loss, High Efficiency: Utilizing polyurethane rigid foam for insulation, our PERT
insulated pipes exhibit exceptionally low thermal conductivity (λ =
0.013-0.03 kcal/m·h·ºC), outperforming conventional insulation
materials by 4-9 times.
Minimal Water Absorption: The high closed-cell rate of the polyurethane foam (approximately
92%) results in a very low water absorption rate of about 0.2
kg/m².
Superior Anti-Corrosion Properties: The polyurethane rigid foam insulation layer forms a tight bond
with the working pipe, effectively isolating it from air and water
infiltration, thus preventing corrosion and ensuring long-term
structural integrity.
Extended Service Life: PERT insulated pipes offer an impressive service life of over 50
years, significantly longer (3-4 times) than pipes installed using
traditional trench or overhead laying methods. This durability
reduces maintenance, replacement costs, and offers substantial
environmental benefits.
Small Land Occupation & Fast Construction: Eliminating the need for large trenches, this solution reduces
earth excavation by over 50% and civil engineering and concrete
usage by 90%, while also shortening the construction period by more
than 50%.
Intelligent PLC Control: Features intelligent operation via PLC control, minimizing manual
intervention, reducing electricity, water, and labor costs, and
enhancing operator safety with a high safety factor.
Customized Production: Tailored production options are available to meet diverse customer
requirements, backed by lifelong technical support and maintenance
services.
Pipe Structure:
Inner pipe: PE, PE-RT, Steel,PERT-II, PE-Xa
Insulation layer: Polyurethane (PPU)
Outer sheath: HDPE
