Product Details
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
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
Consistent and controllable polyurethane density
Void-free rigid polyurethane foam
High bonding strength: Shear strength (friction) between foam and PE casing > 200 KPa
Customizable design: Adjustable thickness of insulation layer and PE casing
High degree of automation in production
