China Plastic Polyurethane Thermal Insulation Tube Manufacturing&Processing Equipment

One-step PERT II insulation pipe production line.
Polyurethane flexible insulation tube extrusion making machine.
PERT II insulation pipes:
The international heating system implements the "plastic replaces steel" plan, and the secondary pipe network reconstructs a new, and the PERT II thermal insulation pipes as a new pipeline, attracting much attention and popularity.
PERT II insulation pipes structures: PERT pipe inner layer + PU foaming layer + HDPE jacket outer layer

PERT II insulation pipes applications:
1. PE-RT II prefabricated direct-buried heat-insulating composite plastic pipe has excellent performance and is widely used in secondary pipe network systems for urban central heating, hot water systems, and HVAC systems.
2.. 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%.
3. Security.

The composition of the PERT II insulation pipe production line:
extruders, extrusion coating head, vacuum calibrating cooling tanks, 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.
