FRP Ducts & Pipes for Corrosive Ventilation and Fluid Handling
Specify fiberglass ductwork and piping for chemical exhaust, wastewater treatment and process media. Hebei Leihong FRP Technology Co., Ltd. reviews media, temperature, dimensions and operating pressure before recommending a construction.
Choose a system
Ventilation Ductwork and Fluid Conveyance Pipes
These products have different design conditions. An exhaust duct sized for airflow and pressure loss is not automatically suitable for liquid pressure service.
FRP Ventilation Ducts
For acid mist extraction, odor capture and connection to scrubber systems where the gas composition and operating conditions have been reviewed.
- Round or rectangular sections, subject to drawing review
- Material choice based on gas chemistry, condensate and temperature
- Elbows, transitions, branches and flanged interfaces
FRP Process and Utility Pipes
For specified liquid handling and industrial water service where pressure class, supports, surge and corrosion barrier are designed for the job.
- Wound pipe construction and selected internal liner
- Pressure and stiffness determined for the specific product
- Flanged, bonded or gasketed connections by design
Material selection
Why Engineers Specify FRP Duct and Pipe Systems
Defined chemical barrier
Select the liner and resin system against the exact medium, concentration and temperature. Compatibility must be checked per application.
Low component weight
FRP can simplify handling for suitable sizes, while supports, lifting and connections still require structural review.
Engineered inner surface
A smooth bore may reduce hydraulic resistance; predicted pump energy depends on diameter, flow rate and the full network design.
Custom geometry
Specify elbows, branches, duct transitions and flange orientations to match approved site drawings and access limits.
Technical sizing
FRP Duct and Pipe Engineering Specification Checklist
Use the two tables below to prepare a quotation. Available nominal diameters, wall thicknesses, pressure classes and standard lengths are confirmed against the requested product and manufacturing method.
Ductwork: airflow and installation
| Input | What to provide | Why it matters |
|---|---|---|
| Air volume | Design and peak airflow; fan system information | Size and pressure-loss review |
| Cross section | Round diameter or rectangular width × height; route length | Fabrication, transport and support |
| Gas stream | Components, concentrations, condensate, dust and temperature | Liner, resin and cleaning access |
| Connections | Flange drawing, elbows, branches, supports and access points | Installation fit and leakage criteria |
Liquid pipework: pressure and supports
| Input | What to provide | Why it matters |
|---|---|---|
| Nominal size | Required bore, route length and available space | Hydraulics and product availability |
| Design pressure | Normal, peak and transient pressure; vacuum if relevant | Pressure class and wall design |
| Liquid properties | Medium, concentration, temperature and density | Chemical liner and load calculation |
| Installation | Buried or aboveground; support span, joints and soil data | Stiffness, supports and joining method |
Applications
FRP Ductwork and Piping in Industrial Projects
Chemical Exhaust
Acid mist extraction and scrubber duct connections designed around gas composition and operating temperature.
Wastewater Odor Capture
Duct routes from basin covers to odor treatment equipment, with attention to condensate and access.
Industrial Water
Selected utility and process water lines with pressure and support design defined for the system.
Process Ventilation
Custom ducts for wet or corrosive exhaust streams, subject to cleanliness and material requirements.
Fabrication and inspection
From Corrosion Barrier Design to Factory Acceptance
Confirm design inputs
Review fluid or gas chemistry, dimensions, structural supports and required standard.
Build liner and structure
Choose the internal barrier and laminate construction for the forming route and loading.
Finish connections
Check fittings, flange interfaces and joint preparation against the approved drawing.
Inspect and release
Confirm dimensions and applicable pressure, leak or other tests under an agreed plan.
Technical FAQ
FRP Duct and Pipe Selection Questions
How should I choose the resin for chemical exhaust or a conveyed liquid?
Provide the exact components, concentration, impurities, temperature and cleaning cycles. Review a named resin grade and laminate design against the actual service; a broad label such as “strong acid” is not enough.
How can outdoor FRP pipework be protected from UV exposure?
Specify climate, exposure duration and appearance requirements. A suitable surface veil, gelcoat or coating can be reviewed for the product, with supporting evidence for the required performance.
Which joining methods can FRP pipework use?
Options may include flanged joints, field-laminated joints and designed gasketed couplings. Suitability depends on pressure class, medium, thermal movement and the approved installation method.
Can you make custom transitions, elbows or branches?
Submit the route drawing, section dimensions, angles, flange pattern and installation clearances. Manufacturing feasibility and any tooling requirement will be reviewed for each fitting.
