Continuous PERT Flexible Insulated pipe production line for
Centralized heating
This production line utilizes a one-step process to continuously
accomplish the extrusion of PERT pipes, polyurethane foaming and
curing, corrugated forming, and online HDPE jacket coating. It is
capable of producing soft or hard polyurethane foam-insulated pipes
with pipe diameters ranging from 20 to 250 mm, making it suitable
for the manufacture of insulated pipes in applications such as
heating networks.
The flexible thermal pre-insulated pipe produced by this equipment
is light in weight and can be rolled up. It has the characteristics
of convenient transportation and construction, less joints and good
toughness. It is especially suitable for the secondary pipe network
of central heating and is a good substitute for buried
pre-insulated steel pipes.
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%

√ Significantly reduce production cost
√ High degree of automation
√ Continuous production avoids restrictions on the length of the pipe
√ Flexible pre-insulated pipe can be directly buried underground, requiring smaller trenches
√ Excellent mechanical properties
√ The pre-insulated pipe is airtight and impermeable,anti-chemicaland
corrosion,and the inner pipe is free from oxidation
√ The pipe can be rolled and transported in rolls, needs less pipe connectors,reduces construction costs, avoids a lot of trouble in
the construction
