The plastic pipe in the outdoor scene is most afraid of long-term "sunbathing" - strong ultraviolet rays will slowly destroy the molecular structure of the pipe, resulting in aging and brittleness of the pipe wall. At best, cracks and water leakage will occur, and at worst, it will directly break and block, which will not only affect the drainage and irrigation function, but also cost a lot of money to dig and repair. This is also the most troublesome problem for many municipal, garden and farmland project leaders when choosing pipes.

For the "sun-aging" pain point of outdoor pipes, HDPE carat pipes of AD Pipes have given a solution - the ability to resist ultraviolet rays is "welded" in the performance of the pipe. This pipeline has been specifically strengthened from raw materials to processes: it is based on high-strength HDPE resin, and a special anti-ultraviolet stabilizer is specially added. Through precise formula debugging, a layer of "invisible protective shield" is formed on the surface of the pipeline, which can effectively block the penetration of ultraviolet rays. In addition, with the company's self-developed spiral winding production process, the anti-ultraviolet ingredients are evenly distributed in every part of the pipe wall to avoid local weak points.

In order to verify the anti-ultraviolet effect, AD Pipe has done strict simulation tests: the HDPE carat pipe was placed in a simulated outdoor strong ultraviolet environment and continuously exposed to the sun for 5,000 hours (equivalent to 5-8 years of outdoor use). The results showed that the tensile strength and impact toughness of the pipe decreased by less than 3%, far below the 10% limit of the national standard. However, under the same test, the performance of ordinary HDPE pipes decreases by more than 20%, and even obvious cracks appear.

This anti-ultraviolet "hard power" makes the HDPE carat pipe the "preferred pipe" for outdoor scenes: the rainwater drainage pipe of the municipal road is laid under the roadside green belt or sidewalk, and the top is often exposed to the sun, so you don't have to worry about being soft in summer and brittle in winter; the rainwater collection system of the community, the connecting pipe from the roof downpipe to the underground water storage tank, will not age in the open air; the main pipe of garden irrigation, buried in the shallow soil but occasionally exposed to the ground, or laid along the green belt, can be stable in the long-term sun; even the irrigation pipe of farmland water conservancy, the field is not blocked, and it is exposed to the sun from spring to autumn, so the carat pipe can still maintain good water transportation capacity.

There is a new district municipal project in a southern city that is very representative: the HDPE carat pipe laid in 2020 is used for rainwater drainage on the main road. After 3 years of high temperature in summer (up to 42 ° C) and typhoon rainstorms, the pipe has not shown any aging or cracking phenomenon. The section of the old city next door with ordinary pipes needs to be dug and repaired 2-3 times a year. In contrast, the maintenance cost of AD pipes has been reduced by more than 70%.

For outdoor pipes, "UV resistance" is not an additional "plus", but a "must". HDPE carat pipe technology makes this "must option" to the extreme, making the pipeline "as stable as Mount Tai" in the sun, which not only reduces the trouble of later maintenance, but also escorts the long-term operation of the project - after all, one installation can be used for more than ten years, which is the most cost-effective choice.
