1. HDPE pipe HDPE pipes are more easily transported than cast iron and ceramic clay pipes because of their corrosion resistance, UV resistance, safety, non-toxicity, light weight, and ease of installation and transportation, making them a popular replacement pipe. HDPE pipe is manufactured on a single screw extruder according to extrusion technology. The HDPE pellets are melted and cast in the mold. The air is introduced according to the star wheel of the circular mold at a working pressure of about 0.8 to 1kg/sq. Until the mold achieves the specified specifications and appearance. Chilled water is used for the solidification process. Estimated service life-50 to 100 years
2. PVC pipe PVC pipes have become another fashionable choice for sewer pipes because of their flexibility and their ease of transportation and installation. The PVC pipe is made by mixing PVC resin, stabilizer, plasticizer, etc. in a mixer, and then sending it from the pipe into a twin-screw extruder equipped with a mold of suitable specifications. According to the heating chamber, the desired appearance is generated in the heating chamber. During the sizing process, the pipe leaving the extruder is cooled according to the working pressure. Estimated service life-50 to 70 years
3. PPR pipe As a new type of pipe, PPR pipe has unique advantages. It can be used as a cold water pipe as well as a hot water pipe. The PR tube interface uses hot melt technology, and the tubes are completely integrated. Therefore, if the installation and pressure test are based, it is not prone to the same long-term leakage aging condition like aluminum pipe. Advantages: moderate price, stable characteristics, heat insulation, corrosion resistance, smooth inner cavity, reliable, impermeable. Estimated service life-50 to 70 years.
In fact, sewer pipes suffer from a variety of factors, such as corrosive sewage, gas, acid production, fluidity standards, working pressure of the surrounding soil layer, working pressure of the surface soil layer, and moving top load. Therefore, the scalability of the pipeline can be defined as the productive use period that will be given when the estimated load is assumed. Over the years, most of the dilapidated pipes have been replaced by higher quality pipes. Technological development has led to the development and design of stronger pipeline raw materials. The useful life of such pipeline raw materials varies from 50 to 100 years. In theory, a longer service life does not necessarily mean the same service life. With the improvement of the quality of life in big cities and the ease of use of natural resources given by big cities, the population appears to be overpopulated. The increase in load on pipelines is not only due to the increase in total traffic, but also due to the improvement of road infrastructure construction, which increases the load to Currently the pipeline.
Regardless of the material of the pipeline, the maintenance of the pipeline is the core of ensuring the service life. Puhui focuses on providing the most professional pipeline solutions for global customers，Contact Us Now~
