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.Widely used in fields such
as building water supply and refrigeration systems.
This kind of pipe is a new generation of PU insulation pipe, with
many advantages, such as light, easy operation, few joints, and
good flexibility.
It is mainly used to transport heat from main pipe system to
housing estate or buildings.

Feature
PE-RTII insulation pipe√ 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
