● Strong resistance to external impact: Excellent recovery performance under external impacts, will not break even in the case of foundation settlement.
● Excellent chemical resistance: Resistant to acid, alkali, and corrosion.
● Superior wear resistance: More wear-resistant than steel pipes, cast iron pipes, and cement pipes.
● Low fluid resistance: Smooth wall surface results in low resistance to fluids, fast drainage speed, and high water flow capacity.
● Stable physical properties: Aging resistant, unaffected by direct sunlight.
● Lightweight: Easy to transport and connect, short construction period, convenient management and maintenance.
● Environmental impact: Non-toxic, harmless to land, recyclable.
● Advantages of Steel Belt Reinforced PE Spiral Corrugated Pipe over PE Double Wall Corrugated Pipe
● Uses steel belt reinforcement, with ring stiffness reaching 15KN/m³, impact resistance, and good adaptability to any foundation.
