Fiberglass Air Duct - China

FRP ducts are ventilation pipes made with a resin or magnesium oxychloride cement matrix and glass fiber as reinforcement.

They are categorized into two main types: organic FRP ducts (resin-based) and inorganic FRP ducts (magnesium oxychloride cement-based).

Our company primarily produces and sells organic FRP ducts with a resin matrix.

Fiberglass Duct Manufacturing Filing Process: Resin-impregnated fiberglass is wound layer by layer around a rotating mandrel, with a sand layer for enhanced rigidity.

Hand Lay-up Process: Fiberglass cloth is applied to the mold surface and then coated with resin.

Multiple layers are stacked, then cured and released.

Suitable for special-shaped pipe fittings.

Core Features and Advantages

Lightweight and High Strength

Weighing only 1/10 of concrete pipes and 30% of steel pipes of the same specification, they are easy to transport and install.

Compressive strength reaches 65 MPa (organic type), with excellent impact resistance.

Corrosion Resistance and Durability

Organic type: Resistant to acid, alkali, and salt corrosion, suitable for corrosive gas emissions in the chemical, textile, and other industries.

Environmental Adaptability

Wide operating temperature range (-40°C to 80°C), resistant to humidity, heat, and freeze-thaw.

Excellent fluid performance

Smooth inner wall, low resistance, 10% higher flow rate than steel pipes of the same specification, reducing energy consumption.

No residual fluid scale, stable flow rate over long-term use.

Economical

Low overall cost, maintenance-free, no anti-corrosion treatment required.

The larger the pipe diameter, the greater the cost advantage.

Application Areas

Fiberglass Duct: Exhaust for corrosive environments such as chemical plants, electroplating plants, and laboratories.

Installation Specifications

Connection Method: Socket-jointed (inorganic models) or flange bolts (organic models), sealed with 8501 rubber strips.

Reinforcement Requirements: Ribs are required for side lengths > 1000 mm, with longitudinal spacing ≤ 1250 mm.

Support and Hanger Spacing: ≤ 2 m for horizontal installation with a side length ≤ 2000 mm, with a hanger diameter ≥ 10 mm.

Quality Control

Wall Thickness Tolerance: -1 to 0 mm for side lengths ≤ 300 mm.

Air Leakage Test: Light leakage testing is required, ensuring zero light leakage at the interface.

Defect Prevention for Inorganic Models: Control slurry uniformity, curing temperature and humidity, and avoid flange deformation.
