Many friends who are engaged in municipal engineering and community support are often torn: Which is more suitable for their project, steel belt pipe or hollow wall winding pipe? In fact, there is no absolute advantage or disadvantage, the key depends on the working conditions.
The steel strip pipe is reinforced with steel strip and formed with a plastic outer layer, resulting in high ring stiffness and outstanding resistance to external pressure. The hollow wall winding pipe adopts an all-plastic winding structure, which has excellent overall corrosion resistance, lighter weight and greater installation convenience.
For different working conditions, the selection logic has its own emphasis:
In the case of buried drainage of municipal main roads, it is recommended to give priority to steel belt pipes. The main road has been rolled by vehicles for a long time, and the external pressure is large. The stiffness of the steel belt pipe ring can reach SN8 and above, which can effectively resist heavy-load extrusion, avoid pipeline deformation and damage, and ensure the long-term stable operation of the drainage system.
The hollow wall winding pipe is more suitable for sewage discharge and rainwater collection projects in the community. The external pressure in the community area is small, and there is no need for extremely high ring stiffness. The all-plastic structure of the hollow wall winding pipe can cope with the acid and alkali components in domestic sewage, and has a long corrosion resistance life. At the same time, it is light in weight, labor-saving in manual handling and installation, and the comprehensive cost of the project is more controllable.
In farmland irrigation and drainage scenarios, hollow wall winding pipes are preferred. Farmland soil contains more sediment, and its smooth inner wall has little water resistance, which is not easy to accumulate scale and block; and it is resistant to soil acid and alkali corrosion, can adapt to the complex soil environment of farmland, and has low maintenance costs.
High salinity or chemical park sewage scenes, be sure to choose hollow wall winding pipe. This type of environmental medium is highly corrosive, and the metal reinforcement layer of the steel strip pipe is prone to corrosion failure. The all-plastic structure of the hollow wall winding pipe has no metal parts, can withstand various corrosive media, and the service life is more guaranteed.
In summary, the selection should be based on the external pressure of the project, the characteristics of the medium, and the installation conditions, and the optimal performance of the pipeline can be achieved by selecting on demand.
