Steel strip pipes are made with U-shaped steel strip and PE composite material, significantly enhancing hoop stiffness without increasing costs, offering much higher strength than coiled or cladded pipes of the same weight. They can address heavy load issues and other challenges, with the advantages of large diameter pipes being even more pronounced. The production range of pipe diameters extends from DN300mm to DN2400mm, with hoop stiffness maintained above 8KN/m². They are lighter and stronger than cement pipes and other plastic pipes.
Characteristics of steel strip pipes:
1. Chemical Resistance: Resists contamination, wastewater, and chemical corrosion; not affected by decayed matter in the soil.
2. Impact Resistance: The pipe wall features a "U"-shaped structure, which is resistant to shock and pressure, and does not crack even under ground subsidence. Additionally, it has strong recovery after deformation and excellent adaptability to the foundation.
3. Aging Resistance: The pipes are typically black and can withstand direct sunlight exposure during storage and construction.
4. Cold Resistance: The pipe will not crack or leak due to expansion in an environment of -60℃.
5. Lightweight: Easy to transport and install, being only 1/8 the weight of cement pipes; requires only an excavator for trenching, no large machinery needed.
6. Easy Connection: Pipe sections can be connected outside the trench and then pushed into place by an excavator, reducing engineering time and costs.
7. Superior Abrasion Resistance: More wear-resistant than steel and concrete pipes, with strong transport capability for domestic water and waste sludge.
8. Excellent drainage and flow: Internally smooth, reducing friction, with fast drainage speed.
9. Cost-effectiveness: Low construction, management, and maintenance costs.
10. Excellent stability of pipeline system: The circular extruded reinforcement structure of the pipe material not only enhances the hoop stiffness of the pipe but also provides root restraint, addressing the tension and well-capping issues caused by longitudinal displacement of the pipeline.
12. Fully Reliable Ring Stiffness: Due to the elastic modulus ratio between steel and plastic materials being greater than 200 and the weight ratio exceeding 7.85, steel strip reinforced pipes, especially large diameter pipes, are more likely to have sufficient safety and reliability in ring stiffness and a relatively higher stiffness-to-weight ratio compared to pure plastic pipes.
