Product Description

PUR Spray PE Wrap Pre-Insulated Pipe Production Line

Energy-Efficient Solution for Heating, Cooling & Oil Transport Applications

Production Line Introduction

The Polyurethane (PUR) Spray Polyethylene (PE) Wrap Pre-Insulated Pipe Production Line is designed for manufacturing polyurethane pre-fabricated direct-buried thermal insulation pipes. These pipes are widely used in:

District heating networks

Industrial cooling systems

Crude oil and chemical transportation pipelines

PUR Spray Polyethylene Wrapped Pre-Insulated Pipe Line for Heating Cooling Oil Pipeline

Product Structure

The rigid polyurethane spray PE-wrapped pre-fabricated direct-buried insulation pipe is composed of:

  • Working Steel Pipe - conveys the medium

  • Rigid Polyurethane Foam Insulation Layer - provides thermal insulation

  • Polyethylene Outer Casing (wound) - offers mechanical protection and corrosion resistance


Application Scope

  • Anti-corrosion & thermal insulation pipelines for heating, cooling, and crude oil transportation

  • Medium temperature: ≤ 120°C (peak ≤ 140°C)

  • Medium pressure: ≤ 2.5 MPa

  • Installation methods: Direct burial (primary), trench laying, or overhead installation

Advantages of Polyurethane Spray Insulation Pipe

  1. Consistent and controllable polyurethane density

  2. Void-free rigid polyurethane foam

  3. High bonding strength: Shear strength (friction) between foam and PE casing > 200 KPa

  4. Customizable design: Adjustable thickness of insulation layer and PE casing

  5. High degree of automation in production
