Production Line for Continuously Corrugated, Flexible Pre-Insulated Pipes (PERT/PEX), for Isoproflex-Type Pipes

Production Line for Continuously Corrugated, Flexible Pre-Insulated Pipes (PERT/PEX), for Isoproflex-Type Pipes

Our flexible polymer pre-insulated pipes offer an integrated solution for efficient fluid conveyance. The core design seamlessly combines a durable inner service pipe, efficient thermal insulation, and a tough outer PE sheath.
As the ideal choice for district energy systems, industrial utilities, and building water supply networks, these pipes provide outstanding adaptability. Their flexibility and corrosion resistance facilitate easy installation in tight spaces, ensuring long-term reliability for both exposed and buried runs in demanding urban environments.

Product Description

The Flexible polymer pre insulated pipes production line is an advanced equipment for producing polymer pressure inner pipes (PERT, PEX) and insulating the inner pipes with polyurethane foam.
The characteristic of this production line is that the pouring process of polyurethane foam is continuous. The inner pipe is continuously conveyed into the pouring area together with the polyurethane foam mixture, then coated and formed with a film, and then passed through a round die head to be coated with the outer protective layer extruded by the extruder.
The pipe coated with the PE outer protective layer can be coiled or cut to a fixed length after passing through the water cooling zone.

The flexible pre-insulated pipes production line consists of the following components:
