Steel Reinforced Corrugated Pipe

Steel belt reinforced corrugated pipe

Bellows Type

The U- shaped steel belt composite PE material is used to greatly improve the pipe without increasing the cost . Under the same weight, the strength is greatly improved compared with  . It can solve a series of problems such as heavy load, and the advantages of large-diameter pipes are more obvious. The diameter of the produced pipe ranges from DN300mm to DN2400mm , and the ring stiffness is maintained above 8KN/m2 . It is lighter and stronger than  other plastic pipes.

The compounding of each layer is carried out in the molten state of the plastic; it is completely different from the secondary melting and molding of winding tubes (hollow wall tubes), so the layers are completely bonded and the fastness is very high.

The surface of the steel strip is specially pretreated to enhance the corrosion resistance of the steel, the adhesion between steel and plastic, and improve  . The plastic raw materials  in a fully molten state , and the overall structure of the pipe is strong and reliable. Due to the use of special materials and processes that not only solve the anti-corrosion problem of steel plates but also the adhesion between steel plates and PE materials, the service life of the pipes is the same as that of pure  , guaranteed to be more than 50 years.

It can be connected by electric hot melt,  internal and external extrusion welding or a combination of multiple connections. The connection is firm and reliable, which can make the pipeline leak-free.

Pipe properties

1.  not corroded by pollution, wastewater and chemicals , and not corroded by rotten substances in the soil;
2. Impact resistance: The pipewall adopts a “U” -shaped structure, which is impact-resistant and pressure-resistant. It will not break even when the foundation sinks. It has strong recovery ability after deformation and has 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 pipewill not be frozen, cracked, expanded or leaked in an environment of -60℃ ;
5. Light weight: easy to transport and construct, only1/8 of the weight of cement pipes , only an excavator is needed to bury the pipes, no large equipment is needed;
6. Convenient connection: the pipes can be connected outside the ditch first and then pushed into the ditch with an excavator, reducing project time and costs;
7. Superior wear resistance: more wear-resistant than steel pipes  , and has better transportation capacity for domestic water and waste residue;
8. Excellent drainage fluidity: smooth interior, reduced friction, and fast drainage;
9. Economical: low construction, management and maintenance costs;
10. Environmental impact:HDPE is a non-toxic raw material, harmless to the environment such as land, and can be recycled.
11. Good stability of the pipeline system: The circular external structure of the pipe not only increases  the pipe , but also has a root resistance effect, solving the tension and top well problems caused by the longitudinal displacement of the pipeline .
12. Completely reliable ring stiffness: Since 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 can easily make pipes (especially large-diameter pipes) have Sufficiently safe and reliable ring stiffness and relatively high stiffness-to-weight ratio
