With the acceleration of urbanization, the sewage treatment system in many cities is facing "growing pains" - the surge in population and the surge in sewage caused by industrial upgrading have overwhelmed the old pipe network: concrete pipes are prone to cracking and lead to sewage leakage, steel pipes are rusted and blocked, which affects drainage efficiency, and pipeline corrosion is a hidden environmental hazard, which has become a "roadblock" on the way to sewage treatment upgrades.

These pain points are precisely the "use" of HDPE carat pipes for AD pipelines. As a high-density polyethylene wound structure wall pipe, its circular corrugated structure is like a "compressive armor", and its ring stiffness far exceeds that of traditional pipelines. Even if it encounters heavy-duty vehicles rolling or soil settlement, it can maintain the integrity of the pipe shape and completely solve the problem of "cracking at one time" of old pipelines. What's more, HDPE material is inherently "resistant to manufacture": acid and alkali substances and microorganisms in sewage cannot erode it, and the service life can reach more than 50 years, reducing the later maintenance cost from the root cause.

In addition to "corrosion resistance and pressure resistance", the "drainage capacity" of AD HDPE carat pipe is equally eye-catching. Its inner wall is as smooth as a mirror, and the debris in sewage is difficult to hang on the wall. In addition, the corrugated structure expands the flow area, and 20% to 30% more sewage is discharged than concrete pipes under the same diameter. There is no need to worry about "sewage backflow" or pipeline blockage in rainy days.

For the construction party, the "flexible connection" design of this pipeline is even more worry-free: there is no need for large machinery to dig deep trenches, and there is no need to wait for maintenance like concrete pipes. It only needs to be connected by hot melt or electric fusion to achieve a firm connection between the pipes. Even if the foundation has slight settlement, the pipeline can "strain with shape" to avoid joint cracking - a 3km sewage pipe network upgrade project in a southern city was completed in just two months, one month earlier than originally planned, which greatly reduced the impact on residents' lives.

As an established enterprise in the plastic pipeline industry, the HDPE carat pipes of AD Pipeline are "tight-fitting" from raw materials to production: imported high-density polyethylene resin is used, and it is produced in accordance with GB/T 19472.2-2017 standards. Each pipe has undergone a number of tests such as ring stiffness and impact resistance. The ring stiffness can reach SN8 or even SN12, which is enough to deal with the ground load of the main road.

A case of upgrading the sewage pipe network in a county in Jiangsu is the best proof: the local old concrete pipes cracked more than 30 places in 10 years, and the sewage leaked and polluted the farmland. After switching to AD HDPE carat pipes, not only the leakage problem was solved, the sewage overflow capacity enhancement was 25%, the concentration of the sewage treatment plant inlet water was stable, the compliance rate rose from 85% to 98%, and the surrounding farmland was also restored to life.

Sewage treatment upgrade is not "tinkering", but to choose the right "long-term reliable partner". With the characteristics of "anti-manufacturing, high efficiency and worry-free", AD Pipeline HDPE carat pipe has replaced the urban sewage pipe network with a "strong heart", allowing the underground "blood vessels" to flow unimpeded, escorting environmental protection and people's livelihood.
