Advantages of the reinforced pipe

1) High ring stiffness

For normal buried sewage plastic structure wall pipe, its maximum ring stiffness is difficult to over SN8. But in new pipe, stiffness can easily reach the surprisingly value of SN8, SN12.5 and SN16, even higher if necessary. In other hand, thanks to plastic properties, the plastic-steel-plastic composite structure could against corrosion very well.Therefore, this composite corrosive-proof pipe could be applied under different kinds of hard conditions. For example, at some coastal areas, due to the soil contains corrosive substance, the concrete pipe will be invalid after a short service time; then the users hope to have a kind of plastic sewage pipe with outstanding anti-corrosive property. But in the past, there is no such high ring stiffness plastic pipe could be selected, and now the new composite plastic pipe gives them a good solution.

2) Saving material cost

Besides the enhanced performance, the other primary advantage is that the new pipe can save material cost obviously. In general it will be thinking as a great improvement if any technique innovation could reduce the material consumption in 10%. However, the steel reinforced polyethylene spiral corrugated pipe has saved the plastic consumption nearly in 50% when compared with other plastic sewage pipe in same diameter and ring stiffness. It is an exciting value for production cost reducing. The polyethylene weight of the composite pipe is only 2/3 of the full plastic pipe; this is a very valuable solution to reduce the material cost under the situation of the plastic price continuous raising.

3) Perfect bonding of steel to plastic

The key point of successful steel reinforced structure is the bonding of steel to plastic. It request that the steel must stick on the plastic firmly, the separate of any two layers is not allowed. To get the perfect bonding performance, we have done a lot of research and examination during the pipe development. Now the process is that steel band will be pre-coated with a special bond resin in order to create a medium layer between the steel and plastic; on the other hand, the processing temperature, pressure and press-cooling time will be strict control to ensure the fusion and bonding has fulfilled under the best proper conditions.

The other process point is to protect the metal layer out of corrosion. In MRP pipe, the steel rib is completely covered with polyethylene, the liquid, air and soil cannot contact with the steel reinforcement, so it guarantee the anti-corrosive performance of the MRP pipe.
