The Core Advantages of Aluminium Flanges
| Core Advantages | Details |
|---|---|
| Lightweight Design | Aluminum alloy material is 40 - 60% lighter than traditional steel flanges, reducing system load and saving installation costs. |
| Excellent Corrosion Resistance | The surface is anodized, suitable for wet, high - humidity, or corrosive environments, extending the service life. |
| Precise Dimensional Accuracy | Manufactured in strict compliance with international standards (such as ISO, ASME) to ensure perfect matching with various pipes and reduce the risk of leakage. |
| Efficient Connection Solutions | Provides various connection methods (welding, bolting) to simplify the installation process and improve construction efficiency. |
| Environmentally Sustainable | Aluminum alloy can be 100% recycled, meeting green building standards and contributing to sustainable development goals. |

FAQs of PIR Foam Pre-insulated Aluminum Duct
Do PIR pre-insulated (PI) ducts require additional insulation after installation?
No. Unlike traditional steel ducts (which need separate insulation layers like fiberglass), PIR pre-insulated panels are factory-insulated with integrated facing. This eliminates the need for secondary insulation work, saving time and labor.
In which scenarios is PIR pre - insulated duct sheet suitable?
It is widely used in commercial buildings such as offices, shopping malls, and hotels, as well as in residential complexes, industrial facilities, healthcare and food processing facilities, and cold storage and refrigeration systems.
How is PIR pre - insulated duct sheet packaged?
-It is usually packaged in plastic film or cartons, with 10 sheets per package.
How to maintain PIR pre-insulated (PI) ducts?
Maintenance is minimal. Regular inspections for joint tightness (to prevent air leakage) and surface damage (e.g., punctures in aluminum facing) are recommended. Cleaning the inner surface periodically (with mild detergents) helps maintain airflow efficiency, especially in hygiene-sensitive areas.
