High-Efficiency Pre-Insulation Pipe Machine PE / PPR / Pert Pipe Extruder Production Line

Product Description

High-Efficiency Pre-Insulation Pipe Machine PE/PPR/PERT Pipe Extruder Production Line

Continue polyurethane foam flexible insulation pipe Extrusion line, makes pipe diameter ranging from 20 to 350mm.

The continue method is a relatively new advanced manufacturing technology. The inner tube, that is, the working tube (usually used of PE-RT, PE material) and the polyurethane foam mixture are continuously injected into the filling area, and the film is covered, followed by the outer protective tube covering the polyurethane insulation layer. Compared with the traditional technology, the continue method can reduce the density of the filled foam and reduce the wall thickness of the outer protective tube, thereby saving costs for the pipe manufacturer.
Continue method is applicable to both hose insulation and rigid insulation pipe.

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.

The system consists of three integrated layers:
Inner service pipe (PE-Xa or PE-RT II material)
Polyurethane foam insulation layer
HDPE outer protective casing

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

Advantages of the PERT pre-insulated pipe production line:
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
