Pert Pre-insulated Pipe Making Machine for Industrial Pipe Systems and refrigeration systems
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
The flexible 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
The system consists of three integrated layers:
Inner service pipe (PE-Xa or PE-RT II material)
Polyurethane foam insulation layer
HDPE outer protective casing
High Heat Resistance: Can withstand continuous operating temperatures of up to 110°C.
Clean and Safe: Smooth inner wall, free from impurities or contaminants.
Smart Heating Applications: Enables automated and unattended operation for heating systems.
Energy Efficiency: Ideal for low-temperature systems using 60°C supply water and 45°C return water, meeting modern energy-saving demands.
Cost-Effective Construction: Reduces excavation work by 40%, significantly cutting civil construction costs.
Material Saving:
Up to 15% less material use compared to PE-RT I
Up to 30% less material use compared to PP-R
Thinner wall thickness at the same pressure rating, without compromising strength
