"Industrial park wastewater transportation project, the advantages of acid and alkali resistance of AD PE coil pipe are highlighted"

the wastewater treatment system of the industrial park, the pipeline is the "blood vessel" connecting production and environmental protection, but the acid and alkali, organic solvents and other corrosive media in the industrial wastewater are constantly eroding the pipeline like "invisible killers" - ordinary steel pipes will rust and leak in a few years, and PVC pipes will slowly become brittle and crack when encountering strong alkali. Frequent replacement not only consumes a lot of manpower and financial resources, but also may lead to production stagnation or environmental protection risks due to pipeline failure. At this time, the acid and alkali resistance advantages of AD PE coils just hit the core pain point of industrial wastewater transportation.

AD PE coils are made of high-density polyethylene (HDPE) raw materials, which themselves have strong chemical stability and can easily resist the erosion of common industrial acids and alkalis such as sulfuric acid and sodium hydroxide. Even if the extreme wastewater with pH value between 1-14 is transported for a long time, the inner wall of the pipeline will not be corroded, dissolved or scaled. For example, in a wastewater collection pipe network renovation project in a chemical park, the seamless steel pipe used before needs to be repaired 3-5 times a year. After replacing it with AD PE coil, it has been running continuously for 3 years without corrosion and leakage, and the maintenance cost has been directly reduced by 70%.

Compared with traditional pipes, AD PE coil has more "full-dimensional" acid and alkali resistance: although the steel pipe has high strength, it will quickly form a rust layer when exposed to acidic wastewater, which will not only reduce the diameter of the pipe and affect the flow, but also pollute the wastewater. PVC pipe is acid-resistant but not resistant to strong alkali. When encountering high-concentration sodium hydroxide solution, the pipe wall will gradually lose its toughness, and even crack directly at low temperatures in winter. Whether the AD PE coil is to transport acid-containing pickling wastewater or sodium hydroxide-containing alkaline wastewater, it can maintain structural stability and will not have "partial" problems.

In addition to acid and alkali resistance, the flexibility and construction convenience of the AD PE coil are also very suitable for the needs of the industrial park - the coil can be coiled and transported, and the site is connected by hot melt welding to form a whole. There are no joints to reduce leakage points. Flexibility allows it to adapt to the complex terrain in the park. Even if it encounters underground pipelines or obstacles, it can flexibly turn without digging a lot of road surface, and the installation efficiency is more than 30% higher than that of traditional straight pipes.

For industrial parks, the reliability of wastewater pipelines is directly related to production efficiency and environmental compliance. With its outstanding acid and alkali resistance advantages, AD PE coils have completely solved the old problem of "pipeline corrosion" in the transportation of industrial wastewater - no longer have to worry about the trouble of frequent pipe changes, no longer have to be afraid of environmental hazards caused by leakage, and can operate stably for a long time after one investment. Whether it is the pipe network laying of the new park or the pipe network transformation of the old park, AD PE coils have become the "assured choice" of more and more parks. With the hard strength of acid and alkali resistance, it has established a "protective wall" for the transportation of industrial wastewater.
