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

Technical Process
  1. Steel pipe loading
  2. Pipe clamping & conveying
  3. PE jacket extruding
  4. PU foaming
  5. Hydraulic correction of foam layer
  6. Spray cooling
  7. Positioner correction
  8. Pipe connector cutting
  9. Electric acceleration pipe removal
  10. Heat shrink band end protection
  11. Finished pipe inspection
  12. Marking, packaging & offloading
