●FRPP Corrugated Pipe: Higher ring stiffness and greater reliability compared to PE corrugated pipe.
●Strong resistance to external impact: Excellent recovery performance under external impact, will not rupture even in the case of foundation subsidence.
●Excellent chemical resistance: Resistant to acids, alkalis, and corrosion.
●Superior wear resistance: More wear-resistant than steel pipes, cast iron pipes, and concrete pipes.
●Low fluid resistance: Smooth wall surface results in low resistance to fluid, quick drainage speed, and high flow capacity.
●Stable physical properties: Resistant to aging, surface unaffected by direct sunlight.
●Lightweight: Easy to transport and connect, short construction period, and convenient management and maintenance.
●Environmental impact: Non-toxic, harmless to land, and recyclable.
●The superiority of steel-belt reinforced PE spiral corrugated pipe compared to double-walled PE corrugated pipe.
