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%
Note: According to relevant Chinese national standards and draft
