Flexible PU Foaming Pert Insulation Pipe Extruder Machinery for Underground Pipe System
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.
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
Pipe Structure:
Inner pipe: PE, PE-RT, Steel,PERT-II, PE-Xa
Insulation layer: Polyurethane (PPU)
Outer sheath: HDP
The pre-insulated pipes production line consists of the following components:
1) Production line for inner pressure pipe (PERT, PEX)
2) Inner pipe unwinding device
3) Pipe feeding device
4) Conveyor
5) Pipe centering device
6) Preheating and temperature control
7) Film feeding device
8) High-precision foaming machine
9) Forming machine with temperature control
6) Extruder for casing pipe and water cooling
7) Pull-off device
8) Winding machine
PE-RTII insulation pipe
It saves the raw materials for using PE-RT II pipe.
Example: Level 2 design pressure: 10 Bar; for cold and hot water transfer in buildings
Selection of different material pipes: the highest PE-RTIIS value; the thinnest wall thickness
Compared to PERT I, PERT II can reduce material use by 15%
Relative to PP-R, PERT II can reduce material use by 30%
Note: According to relevant Chinese national standards and draft
Advantages of the PERT pre-insulated pipe production line:
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
International:
Up to now, there are only a few foreign companies engaged in PERT II cryogenic pipelines, mainly in northwest Europe, Russia and the Middle East.
