Municipal Double Wall Corrugated Pipe Product Introduction:

The steel belt reinforced plastic drainage pipe is made of polyethylene as the inner and outer layer matrix material, with the surface coated with high-performance adhesive resin and bent into a waveform steel belt as the main supporting structure. On the production line, it is wound and co-extruded into an integrated spiral corrugated pipe. This product combines the high rigidity and high strength of steel with the corrosion resistance, wear resistance, and flexibility of plastic, allowing the pipe to achieve a certain level of ring stiffness while solving the corrosion problem of steel, compensating for the low ring stiffness of large diameter all-plastic buried drainage pipes.

1.1 Product Name

The full name is steel belt reinforced polyethylene (PE) spiral corrugated pipe, which can also be referred to as steel belt reinforced polyethylene drainage pipe, steel belt reinforced drainage pipe, etc.

1.2 Implementation Standard: Implementing CJ/T255—2006 "Steel Belt Reinforced Polyethylene (PE) Spiral Corrugated Pipe for Buried Drainage"

1.3 Product Structure: The pipe wall structure consists of three layers: the inner layer is a continuous solid wall PE inner pipe, with a (shaped like a "U") annular wave steel belt reinforcement wound around the outer layer of the inner pipe, and the outer layer is compounded with polyethylene, forming an integrated spiral corrugated pipe.

Nanyang Steel Belt Corrugated Pipe Characteristics:

1. Chemical Resistance: Not contaminated by sewage and chemical corrosion, not corroded by decaying materials in the soil;

2. Impact Resistance: The pipe wall adopts a 'U' shaped structure, which is impact-resistant and pressure-resistant, and will not crack under foundation settlement; it also has strong recovery after deformation and good adaptability to the foundation;

3. Aging Resistance: The pipe is usually black and can withstand direct sunlight during storage and construction;

4. Cold Resistance: The pipe will not crack or leak in a -60℃ environment;

5. Lightweight: Easy to transport and convenient for construction, weighing only 1/8 of that of cement pipes, requiring only an excavator for burial without large equipment;

6. Convenient Connection: The pipe can be connected outside the trench and pushed into the trench with an excavator, reducing construction time and costs;

7. Superior Wear Resistance: More wear-resistant than steel pipes and cement pipes, with strong transportation capacity for domestic wastewater and waste residue;

8. Excellent Drainage Flow: The inner surface is smooth, reducing friction and allowing for fast drainage;

9. Economy: Low construction, management, and maintenance costs;

10. Environmental Impact: HDPE is a non-toxic material that is harmless to the land and other environments, and can be recycled;

11. Good Stability of Pipeline System: The round external reinforcement structure of the pipe not only increases the ring stiffness but also provides root resistance, solving the problem of tension and top well caused by longitudinal displacement of the pipeline;

12. Completely Reliable Ring Stiffness: Due to the elastic modulus ratio of the two materials being greater than 200 and the weight ratio greater than 7.85, the steel belt reinforced pipe is much easier to achieve sufficient safety and reliable ring stiffness as well as a relatively high stiffness-to-weight ratio compared to pure plastic pipes.

Nanyang Steel Belt Corrugated Pipe Construction Method Introduction:

Many construction units, during the laying process of the pipes, directly bury soil mixed with construction waste into the trench after laying the pipes, which is incorrect and can cause significant damage to the pipes. Please follow the construction methods below.

The construction of double wall corrugated pipes is different from that of ordinary concrete pipes. If the construction personnel do not understand the characteristics of double wall corrugated pipes and use traditional reinforced concrete pipe construction techniques, it will affect the construction quality of the pipes and cannot guarantee the normal operation of the pipes. First, the double wall corrugated pipes are lightweight, and it is necessary to ensure that the pipes do not float during construction. Secondly, the compaction of the bottom cushion layer and backfill soil determines the load capacity of the "pipe and soil" system and the radial deformation rate of the pipe. To achieve the effect of "pipe-soil interaction," the compaction of the bottom cushion layer and backfill soil must meet design requirements. To achieve these two points, it is essential to ensure that there is no standing water in the trench during backfilling, do not backfill with water, and do not backfill with silt or organic matter. The backfill soil should not contain stones, bricks, or other hard debris; for areas with high groundwater levels, the groundwater level should be lowered to below the lowest point of the trench, and lowering groundwater should be stopped only when the project is no longer affected by groundwater or meets the strength requirements of the foundation and pipe buoyancy resistance.

Nanyang Steel Belt Corrugated Pipe Quality Control:

The company has passed the ISO9001 quality management system and ISO14001 environmental management system certification, establishing a three-level quality control and responsibility system. It employs an advanced ERP management system, ensuring traceability of product quality. The company's laboratory testing equipment is complete, and it works closely with the National Chemical Building Materials Testing Center. In addition to strict factory tests, products are also periodically sent to the National Chemical Building Materials Testing Center for type testing. The company's products are produced using raw materials and advanced equipment, with strict process control to ensure that the products leaving the factory meet quality standards.

Nanyang Steel Belt Corrugated Pipe Transport and Storage:

1) During loading and unloading transportation, the pipes should not be subjected to severe impacts, drops, or heavy pressure;

2) When mechanically loading and unloading pipes, the two lifting points on the pipe should be about 1/4 of the pipe length from both ends;

3) The bottom of the vehicle or ship contacting the pipes should be as flat as possible, and measures should be taken to prevent rolling and mutual collision, avoiding contact with sharp objects to prevent scratching the pipes.

Storage: Pipes should be stored away from heat sources and chemical contaminants in a flat, well-ventilated warehouse. If stored outdoors, there should be a cover. Pipes should be stacked horizontally and neatly.
