One-step PERT II insulation pipe production line.
PERT II thermal insulation pipe making machine.
Hot spring heating piping system extrusion machine.


PERT II insulation pipes structures:
The pe-rt II prefabricated direct buried insulation pipe has three layers: 1. the outer layer is hdpe high density polyethylene pipe, 2. the middle layer is polyurethane foam insulation layer, and the inner layer is work pipe PE-RT II pipe. The three layers are closely combined.



PERT II insulation pipes advantages:
1. Reduce project costs.
2. Low heat loss and energy saving.
3. Anti-corrosion, good insulation performance, long service life.
4. It occupies less land, is quick to construct and is conducive to environmental protection. Directly buried heat pipes do not need to build huge trenches. They only need to insulate the underground heat insulation pipes, which greatly reduces the project's land occupation, reduces earthwork excavation volume by more than 50%, and reduces civil engineering masonry and concrete volume by 90%. At the same time, the insulation pipe processing and the trenching in situ are carried out in parallel, and only the on-site joints can shorten the construction period by more than 50%.
5. Security.




The composition of the PERT II insulation pipe production line:
extruder, extrusion coating head, vacuum calibrating cooling tank, automatic correcting device, tractor, cutting machine, stacker, polyurethane foaming machine, etc.







PERT II insulation pipe Production line features:
The production line realizes one-time molding process of the inner tube, foam insulation, and outer protection layer. The operation is simpler, the stability is better, the production can be continuous, the quality is guaranteed, the reject rate is low, and the cost is low.
The special screw design ensures full melting, constant pressure, good plasticizing effect, stable raw material extrusion stability and continuity.
