FRP Ducts and Pipes for Odor, Gas and Industrial Media

PRODUCT OVERVIEW

Lightweight and Corrosion-Resistant Ducting and Piping Systems

FRP ducts and pipes are widely used where metal systems are affected by corrosion, chemical attack, humid exhaust or long-term maintenance requirements.

Fiberglass reinforced plastic can be manufactured into straight pipes, round ducts, rectangular ducts, elbows, tees, reducers, branches, flanges and custom transition pieces.

We manufacture according to project drawings, dimensions, pressure, temperature, chemical medium, airflow and installation requirements.

FRP duct and pipe fabrication
ENGINEERING AND FABRICATION

System Design Should Match Pressure, Medium and Support Conditions

ENGINEERING CONSIDERATIONS

Important Factors Before Manufacturing

Duct and pipe design should consider internal pressure, vacuum, temperature, medium, support spacing, wind loads and connection details.

01Operating PressurePositive pressure or vacuum affects wall structure.
02Chemical MediumDetermines resin and corrosion liner.
03TemperatureInfluences resin and expansion requirements.
04Support SpacingAffects deflection and reinforcement.
05Connection DetailsFlanges and interfaces must be confirmed.
