FRP piping is lightweight, non-rusting and available with corrosion barriers tailored to specific liquids or gases. It is widely used in chemical transfer, water and wastewater treatment, seawater, brine, odor-control air and industrial ventilation systems. Steel pipe offers high modulus, established pressure design practices and strong resistance to external impact.
The two materials overlap in water, chemical and utility services. The correct choice depends on pressure, vacuum, surge, temperature, support spacing, buried loads, fire exposure, joining methods and maintenance conditions. For large-diameter or corrosive systems where coating maintenance and installation weight are significant concerns, FRP piping usually provides a stronger lifecycle advantage.
