PERT Insulated Pipe Extrusion Machine High-Quality Pre-Insulated Pipe for Heating Networks
Product Description
QINGDAO HUASHIDA MACHINERY CO., LTD has spent two years overcoming 30 technical difficulties and independently developed a new type of One-step PERT Flexible Pre-insulated Pipe Production Line with independent intellectual property rights.
The new One-step PERT Flexible Pre-insulated Pipe Production Line consists of online continuous production processes, including extrusion of pressure-resistant and heat-resistant PERT pipes as the inner working pipe, polyurethane foaming, polyurethane curing and corrugation forming, and final HDPE outer jacket cladding. This production line is suitable for manufacturing both flexible and rigid polyurethane foam insulation pipes, with a pipe diameter range of 20-250 mm.
Flexible insulation pipes produced by this equipment feature light weight, rollability, convenient transportation and construction, few joints and excellent toughness. They are especially suitable for secondary networks of central heating systems and serve as an alternative to buried steel insulation pipes.

Our Advantages
Advantages of Equipment and Products
- Significantly reduced production costs
- High degree of automated production
- Continuous production removes length restrictions on insulation pipes
- Flexible foam insulation pipes can be directly buried underground and require smaller trenches
- Excellent mechanical properties
- Airtight and watertight insulation pipes, resistant to chemical corrosion, and no oxidation of the inner pipe
- Pipes can be coiled and transported in rolls, greatly reducing the use of pipe connectors, lowering construction costs and eliminating many inconveniences
