In urban construction and municipal engineering, old cement pipes used to be the "main force" of drainage systems, but with the increase of service life, problems such as leakage, corrosion, and heavy weight gradually appeared, which not only affected drainage efficiency, but also increased maintenance costs. At this time, HDPE carat pipes have become an ideal choice to replace cement pipes due to their excellent performance, and it is just at the right time! HDPE carat pipes are made of high-density polyethylene, which has strong corrosion resistance, can resist acid and alkali and other media erosion, and their service life far exceeds that of cement pipes. At the same time, their material is lightweight and weighs only 1/8 of that of cement pipes, which greatly reduces the difficulty of transportation and construction, reduces the investment of manpower and material resources, and shortens the construction period. The interface design is scientific, the sealing performance is good, and the leakage problem is effectively eliminated; and it does not contain harmful substances such as heavy metals, can be recycled, and is in line with modern environmental protection concepts. As a benchmark in the pipeline industry, AD Pipeline has always focused on the research and development and production of HDPE carat pipes. With strict quality control and perfect service system, it provides reliable protection for municipal engineering, building drainage and other scenarios. Choosing AD HDPE carat pipes is not only the pursuit of efficient drainage, but also a peace of mind commitment to long-term use. Replace old cement pipes, it is time!
