Performance Characteristics of Steel Reinforced Polyethylene Pipe

Performance characteristics of steel reinforced polyethylene pipe

1. Safe and reliable ring stiffness compared with pure plastic pipes, the reinforced steel belt can easily make pipes, especially large-diameter pipes, have enough safe and reliable ring stiffness.

2. The inner wall is smooth, and the flow resistance is 20~30% lower than that of the cement pipe. The inner wall of the polyethylene (PE) pipe is smooth, the friction coefficient is small, the sediment is not easy to accumulate in the pipe, and the friction resistance is almost unchanged after long-term use

3. Flexible or non-leakage (electrofusion welding, butt welding) connection, good sealing performance, and environmental protection performance. Both sealing connection methods can be manually operated with simple tools, without machinery, which is very simple and fast and achieves reliability and no leakage.

4. Corrosion resistance, the service life of more than 50 years, the service life of high-density polyethylene (PE) pipes can be as long as 50 years

5. Lightweight, fewer joints, no need for large equipment, easy installation, and laying, lightweight, no need for large lifting equipment during installation. Good axial flexibility, low requirements on the flatness and firmness of the bottom of the groove during laying, and strong ability to withstand abnormal stress caused by improper installation

6. On-site production can greatly save transportation costs. The tape can be transported on a reel (ordinary cable reel), and the pipe winding device is simple and compact, which is convenient for manufacturers to transport the device to the vicinity of the construction site. The nearby winding production and supply of pipes greatly reduce the transportation cost of users. 

7. Pipes with strong resistance to abnormal sudden loads can resolve the resulting stress through elastic deformation, and avoid leakage or damage at the pipe joint due to excessive stress and deformation. The comprehensive cost is competitive. The advantages of the material are all in one, and the tube has an excellent overall performance.

Features of steel reinforced hdpe pipe

1. The steel belt as a supporting structure makes the pipe have sufficient ring stiffness to resist external loads, and the inner and outer polyethylene walls endow the pipe with excellent hydraulic characteristics, strong internal and external anti-corrosion capabilities, and moderate axial flexibility. The pipe combines the advantages of steel and plastic materials and has excellent comprehensive performance.

2. Safe and reliable permanent ring stiffness. Since the elastic modulus ratio of steel and plastic materials is greater than 200 and the weight ratio is greater than 7.85, compared with pure plastic pipes, steel belt reinforcement is very easy to make pipes, especially large-diameter pipes, have sufficient Safe and reliable ring stiffness and relatively high stiffness/weight ratio. Since plastic has creep characteristics, and steel does not have creep problems under the conditions of use of drainage pipes, this kind of pipe with steel as the main strength has more stable and durable strength than other plastic pipes of the same type; strong corrosion resistance, Durable;

3. Since the steel strip is coated inside the polyethylene, the pipe has the same excellent and stable chemical properties as the polyethylene pipe and has corrosion resistance to almost all diluted acids, alkalis, salts, alcohols, detergents, and other media. It can transport corrosive substances, and can also be buried in highly corrosive environments with harsh environments such as high salinity and alkali;

4. It has strong resistance to abnormal sudden loads. Due to the high rigidity of the pipe ring and good axial flexibility, the pipe system is rigid and flexible. When sudden loads and disasters such as uneven soil subsidence, groundwater buoyancy, excessive local load on the ground, or earthquakes occur, the steel reinforced hdpe pipe can be adapted through low-stress elastic deformation to avoid leakage at the joint due to excessive stress and deformation. However, due to the excessive rigidity of steel pipes, cast iron pipes or concrete pipes, when the above environmental conditions change and lead to deformation of the pipe base, the internal stress of the pipes and the joints will be too large, which will easily make the pipes unable to withstand the damage of the pipes or the joints will leak and fail.

5. Light weight, easy installation, and low construction cost. Since the plastic-steel winding pipe has a high stiffness/weight ratio, it is lighter than any other pure plastic pipe or rigid pipe with the same ring stiffness. No large-scale installation is required for installation. Hoisting equipment; pipe length (6-12 meters, can be customized according to the inspection well spacing), fewer joints; two connection methods of rubber sleeve plus stainless steel loop and electric hot melt (belt) are easy and quick to operate manually and professional machines, so the installation and construction Total cost are low.

6. Very high wear resistance. The wear resistance of pipeline-grade PE materials and PP materials is much better than that of ordinary metal or cement. Therefore, plastic-steel winding pipes are used to transport ore mud, river water with high sand content, and particles with high impurity content. In the case of sewage or rainwater, the service life of plastic-steel winding pipes is much higher than that of other pipes;

7. Steel reinforced polyethylene pipes safe and non-toxic. The pipe plastic is made of polyethylene resin that can reach the sanitary level of drinking water transportation. It is suitable for large-caliber long-distance gravity self-flow cleaning water supply pipelines and will not cause secondary pollution to the transportation medium.

8. Flexible and leak-free connection ensures reliable sealing. DN≥1200mm hdpe steel reinforced pipes are welded with hot-melt tape inside the pipe, and DN<1200mm is tightly connected with stainless steel loops. Both connection methods can achieve reliable zero-leakage sealing, even after embedding When the axial limited bending deformation of the pipe is caused by the change of external conditions, normal sealing can still be guaranteed.

9. HDPE steel reinforced pipe has long service life. Under normal use conditions, the service life of plastic-steel winding drainage and sewage pipes can reach 50-100 years, which is much higher than the service life of cement or metal drainage pipes, especially under relatively harsh use conditions. The service life may vary by 10 to several 10 times.

10. The special external structure makes HDPE steel reinforced pipe form a good grip with the soil (like a screw screwed in the soil), so the project has a high bearing capacity.

11. The overall cost of the project is low. The foundation of the plastic-steel winding pipe trench does not need a concrete cushion. The market price of the pipe is equivalent to 1/3 of the market price of the cast iron pipe, and the comprehensive cost is equivalent to or lower than the cement pipe.
