HDPE steel belt reinforced spiral corrugated pipe

HDPE steel belt reinforced spiral corrugated pipe

● Structural features:

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.

● Performance advantages:

1. Common caliber range is DN300mm to DN2400mm;
2. Ring stiffness is mainly SN8, SN10, and SN12.5, and the burial depth is mainly within 5 meters;
3. Steel belt is reinforced, with strong compressive performance, and can maintain structural stability under large external pressure;
4. HDPE wrapped steel belt is corrosion-resistant and resistant to chemical erosion.

● Connection method:

heat shrink sleeve connection or electric hot melt tape connection

● Cenários de aplicação:

Mainly used for deep buried, large-caliber, high-load municipal and industrial sewage and drainage projects, rainwater collection, tunnel and underground engineering drainage, etc.
