Distric Supply Hot Water Polyurethane Foaming Pert Flexible Insulation Pipe Production Line
Distric Supply Hot Water Polyurethane Foaming Pert Flexible Insulation Pipe Production Line
Introduction:
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.
Production technology process:
Roll putting machine----Tractor----Far infrared heating device----Pipe centering straightening device----Laminating molding system----Foaming placement----Foam forming----PE layer extruder coating system----Vacuum sizing----Cooling spray----Pipe cutting----Winding forming
○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
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%

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.
Seller provide the technical service with free, and training the workers of buyers.
