Product Description

Product Description
 

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

Product Structure
The pre-insulated pipe consists of:

  • Working Steel Pipe: Conveys the medium.
  • Sprayed Polyurethane Rigid Foam Insulation Layer: Provides thermal insulation.
  • Winding Polyethylene Outer Casing: Protects against corrosion and external damage.

Polyurethane Spray PE Wrapped Pre-Insulated Pipe Production Line for Sustainable Heating and Oil Pipeline Projects

Scope of Application

  1. Applications: Anti-corrosion and thermal insulation pipelines for heating, cooling, and crude oil transportation.
  2. Medium Temperature: ≤120°C (peak <140°C).
  3. Medium Pressure: ≤2.5MPa.
  4. Laying Methods: Primarily direct burial, also suitable for trench or overhead pipeline installation.

Advantages of Polyurethane Spray Insulation Pipe

  1. Uniform and controllable polyurethane density.
  2. No voids in polyurethane rigid foam, ensuring consistent insulation.
  3. Rough polyurethane foam surface with shear strength to polyethylene casing >200KPa.
  4. Adjustable thickness for both polyurethane insulation layer and polyethylene outer casing based on design requirements.
  5. High degree of production automation, enhancing efficiency.Polyurethane Spray PE Wrapped Pre-Insulated Pipe Production Line for Sustainable Heating and Oil Pipeline Projects
