Steel strip pipe utilizes U-shaped steel strip compounded with PE material, enhancing hoop strength without increasing costs, making it superior to spirally wound pipe and Kevlar pipe in terms of weight. It can address issues like heavy loads, etc. Our large-diameter production pipes range from DN300mm to DN2400mm, with hoop strengths maintaining above 8KN/m², significantly lighter than cement pipes and other plastic pipes.
Characteristics of steel strip pipes:
1. Resistant to contamination, waste water, and chemical corrosion; not prone to rust due to decomposing matter in the soil.
2. The pipe wall is designed with a "U" shape structure, making it less prone to cracking even in cases of foundation settlement. Additionally, it boasts excellent recovery after deformation and great adaptability to different foundations.
3. Pipe materials are typically black and can withstand direct sunlight exposure during storage and construction.
4. Tubing is resistant to cracking and leaking due to expansion in -60℃ environments.
5. Lightweight: Easy to transport and install; only 1/8 the weight of concrete pipes, requiring only an excavator for burial without the need for large machinery.
6. Easy to connect, pipe materials can be connected outside the trench first, then pushed into the trench with a bulldozer, reducing engineering time and costs.
7. Excellent transport capacity for domestic wastewater sludge.
8. Smooth interior reduces friction and facilitates rapid drainage.
9. Low construction, management, and maintenance costs
10. The round extruded rib structure of the pipe not only enhances the hoop stiffness of the pipe but also serves as a root restraint, addressing the tension and well-capping issues caused by longitudinal displacement of the pipeline.
11. Due to the elastic modulus ratio of steel and plastic materials being greater than 200 and the weight ratio being greater than 7.85, steel strip reinforcement significantly enhances the hoop stiffness and stiffness-to-weight ratio of pipes, especially large-diameter pipes, compared to pure plastic pipes.
