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

    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
