● Características estructurales:
Similar to double-wall corrugated pipe, the outer layer is also a corrugated structure, but the corrugation is lined with a “U”-shaped steel belt, and the steel belt is coated with HDPE material to form a composite structure.
● Ventajas de rendimiento:
- Common caliber range is DN300mm to DN2400mm;
- Ring stiffness is mainly SN8, SN10, and SN12.5, y la profundidad del entierro está principalmente dentro de 5 Metros;
- Steel belt is reinforced, with strong compressive performance, and can maintain structural stability under large external pressure;
- HDPE wrapped steel belt is corrosion-resistant and resistant to chemical erosion.
● Método de conexión:
heat shrink sleeve connection or electric hot melt tape connection
● Escenarios de aplicación:
