Overview

This duct is designed specifically for harsh environments such as tunnels, mines, and underground construction. It not only ensures air circulation in underground working spaces but also serves as a critical piece of equipment for improving construction efficiency and ensuring personnel safety. Its exceptional durability, extreme flexibility, and easy operation make it a preferred ventilation solution for various infrastructure projects.

Key Features and Benefits

High Flexibility: Its flexible nature allows it to easily navigate complex obstacles, curved tunnel walls, and large construction equipment, allowing for flexible installation and layout without the need for numerous elbows.

Excellent Weather Resistance and Environmental Adaptability

Waterproof and Moisture-Proof: The complete coating ensures the duct is completely waterproof and moisture-proof, preventing mold and deterioration even in the extremely humid tunnel environment, maintaining stable performance.

Flame Retardant and Antistatic: To meet the stringent safety standards of mines and tunnels, our duct is available with optional flame retardant (FR) and antistatic (ESD) properties. It effectively suppresses static sparks and is self-extinguishing, significantly reducing potential risks in flammable and explosive environments. Corrosion Resistance: Excellent resistance to most chemicals and mold, suitable for a variety of complex geological conditions.

Various Specifications and Customization Options

We offer a variety of pipe diameters (e.g., 300mm, 500mm, 600mm, 1000mm, etc.) and lengths to meet the needs of projects of varying sizes.

Custom colors (commonly available in eye-catching yellow or orange for easy identification in dimly lit environments) and lengths can be customized to meet customer needs. Various accessories, such as hanging rings, steel ring reinforced joints, and quick connectors, can be added to enable quick and leak-proof connection to fans and existing piping systems.

Applications

This ventilation duct is ideal for the following applications:

Highway and railway tunnels: Ventilation, dust, and smoke exhaust during construction.

Mining: Forced ventilation of underground working surfaces to ensure air quality and remove harmful gases such as gas.

Underground projects: Construction and maintenance of subway stations, underground shopping malls, and civil air defense projects.

Large culvert and pipeline construction: Internal air circulation and exhaust gas removal. Industrial field: local ventilation and smoke exhaust in factory workshops and warehouses.
