Overview

In construction environments such as tunnels, subways, mines, and large-scale underground projects, safety and efficiency are paramount. We understand this critical need and have therefore introduced this customizable, high-strength, flame-retardant tunnel ventilation duct. It's more than just a pipe; it's a high-performance ventilation solution tailored for harsh industrial environments.

This ventilation duct is meticulously crafted from advanced high-strength polyester fiber and PVC composite materials, combining superior durability, extreme flame retardancy, flexibility, and ease of installation. It can be customized to your specific site layout, completely solving the pain points of traditional ventilation ducts, such as easy breakage, cumbersome installation, and numerous safety hazards. It is the ideal choice for ventilation, dust removal, and fresh air delivery in modern tunnel engineering.

Product Advantages

1. Superior Strength and Durability

Traditional ventilation hoses often break easily due to insufficient strength, even under dragging, friction, or minor impacts, leading to air leaks and affecting ventilation efficiency. Our ventilation duct body uses a high-strength base fabric and abrasion-resistant coating, possessing extremely high tear resistance and abrasion resistance.

2. Top-Tier Flame-Retardant Safety Performance (Crucial!) 

In underground construction environments, electrical equipment, welding operations, and other materials can become ignition sources. Ordinary ventilation ducts are highly flammable and produce large amounts of toxic fumes upon contact with a flame, posing a significant safety hazard. Our ventilation ducts undergo a special flame-retardant treatment, meeting stringent fire safety standards. When exposed to an open flame, they effectively resist fire and self-extinguish upon removal of the flame, greatly inhibiting the spread of fire through the duct. Furthermore, the smoke produced during combustion has extremely low toxicity, buying valuable escape time for construction workers and creating a crucial safety barrier for your project.

3. Flexible "Customizable Length" Service 

Every tunnel project is unique. Fixed duct lengths often result in too many joints, increasing leakage points and making installation more time-consuming and labor-intensive. Our customizable length service solves this problem. You simply provide the required length, and we can produce a continuous section of ventilation duct for you. The benefits are obvious: Reduced joints: Minimizes air leakage and ensures efficient airflow to the working face.

4. Excellent Flexibility and Ease of Installation

Despite its high strength, it maintains excellent flexibility. The pipe can be easily bent and coiled, adapting to complex terrains such as tunnel bends and undulations, requiring minimal bend fittings. Its lightweight design also makes handling and hanging easy and labor-saving, greatly improving the efficiency of the construction team.

5. Highly Efficient Ventilation and Weather Resistance

The smooth inner wall of the pipe minimizes airflow resistance, ensuring efficient and smooth air delivery to the farthest point. Simultaneously, the product possesses excellent acid and alkali resistance, mildew resistance, and moisture resistance, enabling it to adapt to damp and harsh underground environments. It is not prone to aging or deformation, and its performance is stable and durable.

Application Scenarios
