In municipal drainage, sewage transportation and other pipe network projects, HDPE carat pipe has become the industry's preferred pipe material due to its high strength, light weight and corrosion resistance. But few people realize that the "safety lifeline" of the pipeline system is actually hidden in the "connection part" - according to industry statistics, about 80% of pipe network leakage and blockage problems are caused by interface seal failure. In response to this pain point, AD Pipe's HDPE carat pipe connection technology, with industry-leading process design, has created an "unbreakable defense line" for the safety of the pipe network. The core of connection technology is "sealing and firmness", while AD Pipe has developed two mainstream processes of socket electric fusion connection and hot melt connection according to the characteristics of HDPE carat pipe. Take the socket type electric fusion connection as an example. The technology precisely heats the built-in electric fuse wire, so that the contact surface of the pipe and the pipe fitting is evenly fused to form an "integrated" structure. Compared with the traditional connection method, this process realizes the "zero gap" sealing of the interface, effectively avoiding the pollution of soil and groundwater by sewage leakage. At the same time, the welding process precisely controls the temperature and time through intelligent equipment to ensure that the fusion strength of each interface exceeds the pipe itself - even in the complex environment of heavy-duty vehicles rolling on municipal roads and foundation settlement, the connection part can be maintained stable, and the hidden danger of "interface disconnection" can be eliminated. The hot-melt connection process is optimized for the needs of large-diameter carat pipes - the pipe ports are heated to a molten state by a special hot-melt machine, and then quickly docked and pressed, so that the pipes at both ends are completely integrated into a whole. The advantage of this process is that it has "strong anti-settlement ability", which is especially suitable for soft soil foundations or pipe network projects with complex terrain. For example, in a municipal drainage project in a southern city, due to the soft geological conditions, the traditional pipe connection method often leads to cracking of the interface due to foundation settlement. However, after the use of the hot-melt connection technology of HDPE carat pipes, the connection parts are synchronized with the pipe, which effectively resolves the settlement stress, and there is no problem of interface leakage in the three years of project operation. In addition to the leading technical principle, the connection process of AD pipeline also focuses on "construction convenience". Its supporting connection equipment is easy to operate, can be quickly mastered without complex training, and greatly shortens the on-site construction period; at the same time, the "ready-to-use" feature of the interface reduces the waiting time - in a sewage pipe network renovation project in a northern city, after the adoption of AD technology, the connection time of a single section of pipeline was shortened from the traditional 2 hours to 40 minutes, and the overall construction period was advanced by 15 days, effectively reducing the construction cost. For municipal engineering, the "life" of the pipeline system depends not only on the pipe material, but also on the durability of the connection part. The HDPE carat pipe connection technology of AD Pipeline makes the service life of the interface synchronized with the pipe (up to 50 years or more) through the "perfect matching of materials and processes", which fundamentally avoids the embarrassing situation of "the pipe is not damaged, and the interface leaks first". This advantage makes AD Pipeline's HDPE carat pipe the "preferred solution" in many municipal projects - whether it is a drainage pipe network in rainy areas or a highly corrosive sewage transportation system, its connection parts can remain stable for a long time. As a technology leader in the field of HDPE carat pipes, AD Pipeline has always taken "connection safety" as its core research and development direction. By continuously optimizing the connection process, it not only solves the pain points of traditional pipeline connection, but also provides technical support for the "long-term stability" of the municipal pipe network. In the future, AD Pipeline will continue to deepen the connection technology and help the high-quality development of municipal infrastructure buildings in our country with more advanced solutions.
