Product Description
Continuous One-Step PERT Rigid Insulation Pipe Machine for Centralized Heating Systems
Product Overview

High Efficiency One-Step PERT Rigid Insulation Pipe Machine for Centralized Heating Systems


PEXA/PERT prefabricated insulated plastic piping system is a prefabricated three-layer composite pipe for community low-temperature central heating secondary networks (70/55ºC or 80/60ºC), with direct burial, low heat loss, long service life (over 50 years) and easy installation. It consists of PERT inner pipe, PU rigid foam insulation layer and HDPE outer jacket.

Innovative One-Step Continuous Production Process

Unlike traditional pipe-in-pipe batch foaming methods that produce pipes individually, Huashida's advanced manufacturing solution features:

  • Fully integrated continuous production line combining polyurethane (PU) foam insulation application and HDPE outer casing co-extrusion
  • Industry-leading production efficiency (40% faster than conventional methods)
  • Significant energy savings (30% reduction in energy consumption)
  • Consistent quality assurance through automated process control
  • This revolutionary process meets EN 253 standards while delivering superior production economics for modern district heating and cooling systems

Top-tier HDPE casing extrusion line for PUR injected pre-insulated pipes. Production speed is fast, pipe dimension accuracy is precise, and every finished casing meets international quality standards. The equipment is well-engineered, low-noise, and designed for long-term heavy-duty use. Ideal for heating networks, geothermal systems, and industrial thermal transmission pipelines. Truly professional production machinery.

5 stars for this high-performance HDPE jacket pipe extrusion line! It works perfectly with PU foam pre-insulated pipe systems, creating strong, weather-resistant outer casing for municipal and industrial heating projects. The extruder is powerful, forming is one-time finished, and raw material utilization rate is very high. Stable continuous operation, solid mechanical design, and great cost performance. Exactly what our pipeline manufacturing plant needed.
