One-step Polyurethane Insulated Pipe Production Line

Product Overview

The "One-step" Foam Jacket Anti-corrosion & Thermal Insulation Production Line integrates multiple processes, such as applying anti-corrosion coatings, filling thermal insulation materials, and extruding outer protective layers, into a continuous production workflow. This streamlined approach enhances efficiency, reduces costs, and ensures high-quality product output.

This equipment is primarily used for manufacturing polyurethane insulated pipes. It ensures the tight bonding of the steel pipe, insulation layer, and outer protective jacket, resulting in durable, high-performance pipes. With its advanced automation, the system minimizes manual operations, improving product stability and reliability.

Pipes produced with this line are widely used in heating systems, long-distance oil transportation, and buried thermal pipelines, offering extensive application potential and excellent investment returns.

Technical Features

• Versatile Material Options:

Corrosion resistance: Compatible with fusion-bond epoxy powder and various coatings.

Thermal insulation: Options include high-temperature polyurethane foam or black pitch foam.

Outer jacket: Black, UV-resistant, and anti-aging, ensuring durability.

• Robust Layer Integration:
