Product Description

Product Description

The one-step polyurethane insulation pipe production line is an advanced manufacturing system designed for the continuous and efficient production of PU-insulated pipes. It integrates multiple processes-including steel pipe derusting, outer protective PE jacket extrusion, and polyurethane foam injection-into a seamless, automated production flow.

This production line tightly bonds the inner carrier pipe, insulation layer, and outer sheath in one continuous operation. Its high level of automation reduces labor intensity and enhances product consistency. Widely used in heating and oil pipeline systems, this equipment is ideal for industries requiring high-performance thermal insulation solutions.

Specification

Item	Specification
Steel Pipe Diameter Range	Φ48-Φ630 mm
Processing Capacity	≤250 m²/h
Cleaning Level	Sa2.5
Raw Materials Used	Black: Isocyanate, White: Combined Polyether
Main Equipment	External rust removal unit, PE extruder, forming molds, deviation correction unit, cooling unit, cutting unit, transmission unit, spray marking unit

Production Structure

The outer sheath, polyurethane foam layer, anti-corrosion layer, and steel pipe are bonded together during a single continuous process. This ensures a compact structure, optimal thermal insulation, and long service life.

Features

Wide Material Compatibility
Supports epoxy powder coatings and various anti-corrosion coatings; foam options include high-temp polyurethane and asphalt black foam.
Simplified Process
The jacket layer is bonded directly to the foam layer, and the foam layer to the anti-corrosion layer, which is further bonded to the steel pipe-ensuring tight structure and easy operation.
Energy Efficiency
Uses cost-effective PE materials with low energy consumption, minimal environmental impact, and a quick investment return.
High Production Efficiency
Continuous operation ensures high throughput, cost-effectiveness, and reduced waste compared to traditional batch processes.
High Precision
Rubber wheel transmission protects the pipe coating, and a fully automatic deviation correction system ensures high alignment accuracy and working efficiency.
Compact Design
Space-saving layout and streamlined operations contribute to a smaller factory footprint and easier system integration.
