Detailed Product Description
Continuous PERT Flexible Insulated pipe production line for Centralized heating 

Product Description

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.


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

Our Advantages


√ 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
