Thin fluoroplastic outer layer resists acidic condensate and corrosive flue gas.
Steel core provides excellent rigidity and pressure resistance up to 2 MPa.
Suitable for -60°C to 260°C, with low flue gas resistance and a typical fluoroplastic service life of 15–20 years.
General heat recovery with low corrosion risk.
Highly corrosive, low-pressure applications.
Low-temperature flue gas heat recovery requiring corrosion resistance, mechanical strength, and long-term reliability.
