    PUR Spray PE Wrapping Pre-Insulated Pipe Production Line – High-Density PU Foam Insulation for Heating, Cooling & Oil Pipelines

    Product Description

    The Polyurethane (PUR) Spraying Polyethylene (PE) Wrapping Pre-Insulated Pipe Production Line is designed for manufacturing polyurethane prefabricated direct-buried thermal insulating pipes. These pipes are widely used in heating, cooling, and crude oil transportation industries, offering exceptional energy efficiency and durability.

    Product Structure

    The rigid polyurethane spraying polyethylene winding prefabricated direct-buried insulation pipe consists of three primary layers:

    1. Working Steel Pipe: The inner steel pipe is used for conveying the medium (e.g., hot water, chilled water, oil).
    2. Sprayed Polyurethane Rigid Foam Insulation Layer: Provides excellent thermal insulation with uniform and controllable density, ensuring no empty spaces.
    3. Winding Polyethylene Outer Casing: Protects the insulation layer and provides mechanical strength for direct burial.

    Scope of Application

    • Anti-corrosion and Thermal Insulation: Ideal for pipelines in heating, cooling, and crude oil transport.
    • Medium Temperature: ≤120°C (incidental peak up to <140°C).
    • Medium Pressure: ≤2.5 MPa.
    • Laying Methods: Primarily for direct burial; also suitable for trench or overhead pipeline installations.

    Advantages of Polyurethane Spray Insulation Pipe

    1. Uniform & Controllable Density: Ensures consistent thermal performance.
    2. No Voids in Insulation: Rigid foam fills all spaces for maximum efficiency.
    3. High Shear Strength: Rough foam surface provides friction >200KPa with the PE casing.
    4. Adjustable Thickness: Thickness of insulation and casing can be tailored to project specifications.
    5. High Automation: Streamlined, automated production for quality and efficiency.

    Technical Process

    The spraying and winding production process ensures uniform insulation density, improves product quality, and reduces production costs.

    The PUR spray PE winding pre-insulated pipe production line includes:

    1. Steel Pipe Outer Wall Shot Blasting Line: Prepares the steel pipe surface for optimal adhesion.
    2. Polyurethane Spray Molding Line: Applies a uniform layer of rigid foam insulation.
    3. Polyethylene Sheet Extruding & Winding Line: Forms and wraps the protective PE outer casing.
    4. Water Cooling Line: Cools and solidifies the casing after application.
    5. End-Cutting Equipment: Trims pipe ends for precise length and clean edges.
