HDPE pipe is the perfect combination with all the merits of no-press plastic pipe and the high-strength of steel reinforcing

Application Areas

Because steel reinforced spirally wound HDPE drainage pipe is the perfect combination with all the merits of ordinary no-press plastic pipe and the high-strength of steel reinforcing segment, it can meet all demands in project applications completely. It can be widely used in gravity delivery with various media of corrosive or non-corrosive agent. Specific examples are as follows:

1. Public works: used as drainage pipe and blow-off pipe while buried under the ground.

2. Road works: used as soakaway trench or drainage pipe in railways and express ways.

3. Industry: widely used as sewage pipe in industry area.

4. Construction works: used as rain pipe of buildings, underground drainage pipe, blow-off pipe, vent pipe, etc.

5. Dirty water collecting pipe in refuse landfills.

6. Large-scale port and wharf projects: used as drainage pipe and blow-off pipe in projects of large-scale airport, port and wharf.

7. Sport stadium: used as soakaway trench and drainage pipe in sport stadium, such as golf course and football field.

8. Water conservancy project: used as water-head pipe and irrigation pipe.

9. Mine field: used as vent, blast, drain and slurry pipe.

10. Communication engineering: used as railway and highway communication pipe, communication cable pipe and optical cable protective pipe.

11. Water storage system: used in the water storage system to trap slow-flowing stream.

12. Agricultural engineering: used as irrigation pipe on the farm, in the garden,the tea garden and the forest belt.

13. Seawater transporting pipe.

14. Clear the river channel

Features and Benefits

1. Distinguished comprehensive performances

Worked as the braced structure, the steel belt offers enough ring stiffness to resist soil loading. PE pipe has excellent hydraulic characteristic, high ability of internal and external corrosion prevention and moderate axial toughness. And steel reinforced spirally wound HDPE drainage pipe is integrated advantages of steel and plastic. Therefore, this pipe possesses distinguished comprehensive performances.

2. Safe and reliable ring stiffness

Steel and plastic have excellent modular ratio and light weight and their ratios are over 200 and 7.85. Strengthening the steel belt could easily provide the pipes (especially pipes with the large diameter) with enough safe and reliable ring stiffness and fairly high weight ratio when comparing with pure plastic pipes.

3. Light weight

Steel reinforced spirally wound HDPE drainage pipe has fairly high stiffness weight ratio, therefore, its weight is lighter than any other pure plastic pipes with the same ring stiffness.

4. Simple installation, good sealing and low cost of construction

Large-scale handling appliance is not required when installing the light weight pipes. Because of its good axial toughness, requirements of the undercut flatness are low when laying and firmness. Moreover, it has good capability to bear abnormal stress caused by improper assembly. All sealed placements can be manually operated with simple equipments, simply and speedily without leak while no machine is needed.

5. Producing on the construction site, saving the transportation charges and construction costs heavily

Shaped Steel-plastic composite strips can be coiled delivered. The device for winding strips is quite simple and tight. So it’s very convenient for the manufacturer to deliver the device to the construction site and then produce pipes nearby. Transportation charges is heavily reduced by transporting strips instead of pipes. Without needs of transportation by oversize vehicles, the length of pipe can be determined at random so a large number of interface connections and work to break pipes are reduced. All in all, costs is reduced greatly.

6.Strong load capacity to resist improper burst

Because the pipes are with high ring stiffness and good axial toughness, when burst load and disasters like soil differential settlement, ground water level rising, overload of part of the ground and earthquake happen, the stress can be defused through the elastic deformation of the pipes to avoid the leak or damage of the pipe connections.

Other Features Same with PE Pipes:

1. Anticorrosion

PE pipe can be used to deliver corrosive liquid like acid and alkali for its anticorrosion. The pipe can also be installed in the corrosive environments such as moisture. Specific anticorrosion performance is shown in standard ESO/TR 10358.

2. Anti- ultraviolet

Carbon black stability factor is one raw material of PE pipe which is anti-ultraviolet. For this reason, the pipe could be used outside for a long time and there is no need to worry about the change of the pipe’s nature.

3. Light weight

Installation costs will be saved for the characteristics of easy transportation and installation which result from light weight.

4. Smooth internal surface

The smooth internal surface of the PE pipe will minimize the energy loss caused by friction and sedimentation is not easy to produce. Friction drag is almost unchanged for long-term usage.

5. Impact resistance

High impact resistance of PE pipe leads to less fractures and damages during delivery and installation.

6. Easy installation

Welding joint after heating PE pipe is going to assure the intensity of the connections and avoid the leak.

7. Toughness

Moderate toughness of PE pipe can make the pipe easily be installed along the pipe ditch, easily avoid the obstacles during pipe laying and suit to the soil settlement of the marsh land and soft spots.

8. Nonpoisonous

Black HDPE pipe has passed the inspection of health-related departments and being licensed to use.

9. Abrasion resistance

Lifetime of HDPE pipe is more than four times as long as steel pipe after the experiment of mortar abrasion.

10. Long operating life

Service life of the HDPE could be as long as 50 years.
