Continuous PUR Spray PE Wrapping Pre-Insulated Pipe Production Line for District Heating
Product Overview

Huashida's independently developed patented PUR spray PE wrapping pre-insulated pipe production line adopts continuous polyurethane spray-foaming and PE-wrapping technology to manufacture large-diameter insulated steel pipes ranging from 508-1620mm. This turnkey equipment is specially engineered for industrial pipeline thermal-insulation applications.

Backed by multiple national utility patents and third party certified Level-5 technology rating, this line holds the highest independent technical verification for pre-insulated pipe production machinery in China, plus the honor of Shandong Province First Set of Technical Equipment.

As a complete patented turnkey system, it integrates three core production modules: external pipe Sa2.5 shot blasting & derusting line, continuous polyurethane spray foaming unit, and PE wrap winding production line.

PUR spray pre-insulated pipe production line overview Industrial pipeline insulation manufacturing process Pre-insulated pipe production line components PUR foam insulation technology
Applications
  • Industrial Pipeline Thermal Insulation: ≥88% closed-cell PUR foam maintains process fluid temperature and minimizes heat loss
  • Oil Gas Transmission Pipeline Insulation: Preserves oil viscosity and reduces heat loss across long distance pipelines
  • Chilled Water Distribution Networks: ≤0.05% water absorption rate blocks moisture ingress and prevents insulation degradation
  • Chemical Fluid Transport Pipelines: Delivers stable thermal insulation and corrosion protection
  • District Heating & Hot Medium Transport: Working temperature ≤120°C (peak ≤140°C), medium pressure ≤2.5MPa
  • Direct Buried, Trench & Overhead Industrial Pipeline Installation: Trinity structure provides integrated corrosion resistance and thermal insulation
Key Features
  • National Patented & High Level Technology Certification: Multiple national utility patents and Level-5 technology rating
  • High-Quality PUR Spray Foaming Performance: ≥88% closed cell ratio and ≤0.05% water absorption
  • Broad Industrial Pipeline Application Coverage: Designed for oil gas transmission, chilled water distribution, and chemical fluid transport
  • High Capacity Production Output: 3-4 units per hour for large diameter 508-1620mm pre-insulated pipes
  • Stable Trinity Molding Structure: One-time synchronous forming eliminates delamination risk
Advanced PUR spray manufacturing system PE wrap winding technology Insulated pipe manufacturing process
Production Process
  • Steel pipe surface shot blasting & derusting (Sa2.5 international cleanliness standard)
  • Medium frequency induction preheating with precision temperature control
  • Uniform continuous polyurethane spray foaming with customizable thickness from 3-100mm
  • HDPE strip wrapping over PU foam layer to form protective PE outer casing
  • Finished pipe end trimming and quality inspection

Complies with EN253, GB/T29047, CJ/T114 international pre-insulated pipe standards.
