In municipal engineering, building drainage and other fields, HDPE carat pipe has become a commonly used pipe due to its corrosion resistance and high strength. The latest 183-meter coiled HDPE carat pipe introduced by AD Pipeline has optimized the transportation link on the traditional basis and brought new convenience to engineering construction. Traditional HDPE carat pipes are mostly fixed-length straight pipes, which are limited in length during transportation. The number of loads that can be loaded on a single vehicle is limited, which not only increases the frequency of transportation, but also may cause damage to the pipeline due to frequent loading and unloading. At the same time, the straight pipe takes up a lot of space in the carriage, and the logistics cost remains high. AD Pipeline 183-meter coiled HDPE carat pipe adopts a special coiling process to roll the original long-distance straight pipe into a regular circular coil. The length of a single coil reaches 183 meters, which greatly increases the single transportation volume. This means that the same transport vehicle can be loaded by more than 30%, the number of transports is reduced, and the logistics cost is effectively reduced. The coiled design not only saves space, but also ensures the stability of the transportation process through professional fixtures, reducing the damage caused by bumps and collisions in the pipeline. For emergency projects that require quick response, the coiled design makes pipeline transportation more flexible, and the transportation plan is planned in advance to avoid delays in material supply affecting the construction period. In the construction process, the 183-meter coiled HDPE carat pipe also performs well. Compared with straight pipes, the coiled pipe is easier to unfold in a narrow site. The construction personnel can flexibly cut and connect according to the site conditions, shortening the construction period. At the same time, AD Pipeline strictly controls the quality of HDPE materials to ensure that the core properties such as ring stiffness and corrosion resistance of the coil meet engineering standards, providing protection for the long-term stable operation of the pipeline system.
