Fiberglass Ventilation Ducts

Fiberglass ventilation ducts refer to both fiberglass air ducts and fiberglass fan enclosures, known for their resistance to acids and alkalis, corrosion, and long service life. They are primarily used in places that require the discharge of corrosive exhaust gases, such as textile, chemical, printing, metallurgical, and underground facilities.

Characteristics of Acrylic Steel Ventilation Ducts:

Corrosion-resistant, alkali-resistant, and suitable for facilities requiring the discharge of corrosive waste gases: Textile, chemical, printing, metallurgy, etc.

1. Corrosion Resistance - FRP pipes can withstand corrosion from acids, alkalis, salts, seawater, untreated wastewater, corrosive soil or groundwater, and numerous chemical fluids.

2. Excellent heat and cold resistance – The temperature range for FRP pipes is generally between -40℃ and 120℃.

3. Lightweight and High-Strength, Easy to Transport and Install - The specific gravity of FRP pipes is between 1.7-1.9. Compared to other materials with the same pressure and pipe diameter, FRP pipes weigh approximately 30% of steel pipes per unit length. This makes transportation and installation extremely convenient. FRP pipes can be up to 12 meters in length, with quick and easy installation. Additionally, it eliminates the need for welding and anti-corrosion treatments required for steel pipe installation.

4. Low Friction Resistance, High Transmission Capacity - The inner surface of the FRP pipe is extremely smooth with a small roughness coefficient, enabling the hydraulic coefficient C to be maintained within the range of 145-150 over a long period. The tested frictional loss coefficient f of the water flow is 0.000915, significantly reducing fluid pressure loss along the pipeline and enhancing transmission capacity by over 20%.

5. Excellent electrical and thermal insulation properties; FRP is a non-conductor, making the pipes highly insulated, suitable for use in areas with dense power and telecommunication lines and frequent lightning strikes. The thermal conductivity of FRP pipes is very low (0.25 kcal/m·h·℃), thus ensuring good insulation and minimal heat loss.

6. Rust-Free - As glass steel pipes are composed of non-metallic materials like resin and glass fiber, they do not rust during use or storage, thus no anti-rust or rust-removing treatment is required.

7. Highly Customizable - The specific performance and shape of the spiral-wound glass steel pipe can be designed according to the actual usage.

① The winding angle during winding can be designed to achieve different longitudinal/lateral strength distributions for the tube.

② Wall thickness can be designed to accommodate varying internal and external pressures.

③ Materials can be designed to achieve various corrosion resistance, flame retardant, and dielectric purposes.

④ Tailstock design options are available for different installation conditions, to enhance engineering installation speed.

8. Diverse and Flexible Connection Methods: The joints for wrapped fiberglass pipes come in various options, including flat-end splicing, flange connections (with girth bands), socket and gasket joints, O-ring connections with locking devices, and threaded joints. These can be flexibly chosen based on specific construction conditions.

9. Repairable and easy to maintain.
