Polyurethane insulated pipes are prefabricated pipes closely composed of steel pipes, rigid polyurethane foam insulation layers, and glass fiber reinforced plastic (i.e., FRP) outer protective layers.
- Core Pipe Diameter: Sizes from DN20 to DN2000
- Insulation Thickness: 30mm to 150mm
- Pipe Lengths: Custom lengths
- Temperature Range: -50°C to +150°C
- Standards: ISO 9001, ISO 11426, and EN 253
Introduction
Polyurethane insulated pipes have excellent characteristics such as light weight, high strength, thermal insulation, sound insulation, flame retardancy, cold resistance, corrosion resistance, non-water absorption, and simple and quick construction. They have become indispensable materials for thermal insulation, waterproofing and plugging, and sealing in industrial sectors such as construction, transportation, petroleum, chemical industry, electric power, and refrigeration.
Polyurethane insulated pipes are used for various indoor and outdoor pipelines, as well as insulation and cold preservation projects of various pipelines such as central heating, refrigeration, oil transportation, and steam transportation, central air-conditioning pipelines, and industrial pipelines in chemical, pharmaceutical and other industries.
