High-Efficiency Flexible PERT Insulated Pipe Extrusion Line for Hot Water & Heating with Continuous One-Step Production

When it comes to modern heating systems, efficiency, durability, and cost savings are everything. That's why Qingdao Huashida Machinery Co., Ltd. has developed the Flexible PERT Insulated Hot Water Pipe Production Line - a cutting-edge solution for producing high-performance pipes that deliver heat exactly where it's needed, with minimal energy loss.

This production line combines innovative one-step extrusion technology with precision control systems, ensuring every meter of pipe is perfectly insulated, exceptionally flexible, and built to last.

• Continuous One-Step Production - The pipe and insulation are produced in a single process, saving time, reducing labor, and ensuring seamless quality.
• Lower Production & Installation Costs - Pipes can be coiled for easy transportation and installed with fewer joints, cutting down both material and labor expenses.
• Outstanding Thermal & Mechanical Performance - Soft foam insulation keeps heat inside, while the PERT inner pipe resists high temperatures, pressure, and oxidation.
• Flexible & Direct-Bury Capability - Pipes can be directly buried underground in smaller trenches, minimizing construction disruption.

• Central heating secondary network pipelines
• Underfloor heating systems
• Industrial hot water circulation
• Replacement for underground secondary steel insulated pipes

Whether in harsh winter climates of Northern Europe or rapidly growing urban heating networks in Asia, this flexible insulated pipe meets the toughest demands while staying cost-efficient.
