Product Description

PERT Fiber-Reinforced Flexible / Rigid PU Insulated Pipe Integrated Production Line

Product Description

The production line adopts international advanced technology, combining modern automation with efficient production processes, which can significantly improve production efficiency and reduce production costs. Has good sealing performance, no chemical corrosion or oxidation in the inner tube.

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:

Up carrier pipe--pulling up to line--pipe catching connect--transport forward---put into seal &cover film device--foaming--foam curing ---PE cover extruding--vacuum sorb -- spray cooling--checking splice--cutting splice--off-pipe--down off pipe 

Production line composition

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

1. PERT Work pipe; 2- Protective pipe; 3-Insulated pipe; 4-Stander; 
2. d1- Protective pipe outer diameter; e1- Protective pipe wall thickness; e2- Insulation Layer thickness;
3. dn-Work pipe Nominal diameter ;en- Nominal thickness of the work tube.

 

Features

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
