In modern industry, high-temperature air ducts are a key component in many manufacturing processes. They are used to transport high-temperature gases or fumes and therefore need to have superior heat and corrosion resistance. In recent years, high-temperature air ducts made of fiberglass have gradually gained popularity due to their excellent performance. In this paper, we will discuss the advantages of glass fiber high temperature air duct, application areas and its development trend.






the advantages of glass fiber high temperature flexible duct




1. Excellent heat resistance
Fiberglass material can withstand temperatures up to 1000 ° C, which makes it in the high-temperature environment, suitable for high-temperature gas transmission.


2. Lightweight design
Compared with metal ducts, fiberglass ducts are lightweight, which reduces the burden on equipment and optimizes installation and maintenance costs.


3. High corrosion resistance
Fiberglass has good resistance to a variety of chemicals and environmental factors, so that it can still work stably in harsh environments.


4. Excellent insulation properties
Fiberglass provides excellent thermal insulation, reducing heat loss and improving energy efficiency while protecting surrounding equipment and staff.


5. Flexibility and customizability
Manufacturers can customize the size and shape of the duct to meet the requirements of different industrial applications.






Application Areas




Fiberglass high temperature air ducts are widely used in several industries, including:
1. Chemical industry
In chemical production, it is often necessary to transmit high-temperature exhaust and gases. Fiberglass ducts are suitable for flue and ventilation systems of chemical reaction equipment due to their corrosion and high temperature resistance.


2. Metallurgical industry
Many metallurgical processes require the transmission of gases at high temperatures. Fiberglass high-temperature ducts can effectively cope with these extreme conditions and ensure the normal operation of the equipment.


3. Power industry
In power plants, especially thermal power plants, fiberglass ducts are used to discharge flue gases and ensure that environmental protection standards are met.


4. Food Processing
Certain food processes require high temperature steam, and the high temperature resistance of fiberglass ducts ensures food safety and equipment performance.






the future development trend




With the continuous progress of industrial technology, the market demand for fiberglass high-temperature air ducts is expected to continue to increase. Future development trends may include:


1. Enhancement of material properties
Through composite material technology to improve the heat and corrosion resistance of air ducts to meet more demanding industrial conditions.


2. Intelligent
Development of high-temperature air ducts with temperature and pressure sensors to realize real-time monitoring and improve operational safety.


3. Green
With the rise of environmental awareness, future products will pay more attention to the environmental protection of materials to reduce the impact on the environment.






Conclusion




High-temperature air ducts made of glass fiber are gradually becoming the favorite of the market due to their excellent performance and wide application prospects.

I. Comparison of material characteristics: flexibility versus durability



Flexible duct



Material: usually made of wire frame (e.g. spiral steel wire) wrapped with composite material (aluminum foil, polyester fiber or PVC), the outer layer may be added with thermal insulation.
Advantages: lightweight, bendable, suitable for complex spatial layout; strong anti-vibration performance, can adapt to equipment vibration.
Limitations: low airtightness, easy to leak in high-pressure systems; easy to accumulate dust on the surface, long-term use may breed mold (need to be cleaned regularly).



Rigid duct



Material: mostly galvanized steel plate, aluminum plate or stainless steel, connected by welding or flange into a fixed shape (round, rectangular).
Advantages: stable structure, high airtightness, suitable for high-pressure and high-efficiency air supply; smooth surface, low resistance, low long-term maintenance costs.
Limitations: heavy weight, installation requires precise planning; unable to bend, need to cut and reorganize when remodeling.



II. Installation costs: short-term inputs vs. long-term benefits



Flexible duct



Low initial cost: no need for custom shapes, fast installation, 30%-50% savings in labor costs.


Hidden costs: shorter lifespan (10-15 years), high replacement frequency; insulation is prone to breakage and may increase energy consumption.






Rigid duct



High initial cost: requires professional tools for cutting and welding, long installation period; large projects may require customized molds.


Long-term advantages: service life up to 30 years or more; easy maintenance, air leakage rate below 5% (up to 15% for flexible ducts).






III, the applicable scenario analysis: matching the demand in order to efficiently save energy



HVAC system



Flexible air ducts: suitable for residential, small commercial spaces or remodeling projects. For example, when the air conditioning ducts in the attic need to bypass the beams, the flexible ducts can be flexibly adapted.
Rigid duct: large shopping malls, office buildings and other places that require efficient air supply, its low resistance characteristics can reduce air conditioning energy consumption.



Industrial Ventilation



High temperature/corrosive environments (e.g. chemical plants): stainless steel rigid ducts are the only choice for high temperature and corrosion resistance.
Temporary ventilation needs (e.g. construction sites): lightweight flexible ducts allow for quick deployment and easy disassembly upon completion.



Laboratory & Cleanroom



Rigid ducts: easy to clean surfaces and no fiber shedding, meets ISO 14644 cleanliness standards.
Exception: when vibration isolation is required in animal laboratories, flexible connection sections can be used locally.




IV. How to Choose? 5 Key Questions to Help You Decide



Is the space layout complex? → Select Flex.
Does the system require high pressure air supply? → Choose rigid.
Is the budget for short-term savings or long-term investment? → Flexible for short term, rigid for long term.
Is the environment corrosive/high temperature? → Rigid stainless steel duct.
Do you need to remodel frequently? → Flexible is more flexible.



Conclusion: There is no “best”, only “most suitable”.



Flexible ducts win out with low cost and high flexibility for projects with limited budgets or complex spaces, while rigid ducts are the preferred choice for large projects and demanding environments due to their high efficiency and durability. In practice, a hybrid solution (e.g., rigid for mains and flexible for branches) may be more cost-effective.
