from the underground pipe network of municipal water supply to the hydropower transformation of home decoration, PE coil pipe has become a "universal player" in plastic pipes with its advantages of corrosion resistance and flexibility. But its "soft ribs" are also obvious - the sealing problem of the connection point is always like an irregular time bomb: either the hot melt temperature is not well controlled during construction, and the interface is quietly cracked; or the pipe fittings and pipes do not match, and after three or five years, the sealing ring ages and hardens, and water seeps out along the seam. These problems are not big enough, but they are enough to give the construction party a headache: if the municipal project leaks once, it needs to dig up the road surface and rework; if the home improvement leaks once, it may have to pay the renovation fee of the neighbor downstairs, which is very troublesome.

Traditional PE coil connections mainly rely on hot melt sockets or electrofusion, but the pain points have not been solved: for example, the hot melt is entirely based on the experience of workers, the insertion depth is not standard, and there are often situations where "the insertion is shallow and not welded firmly, and the pipe fittings are cracked when inserted deeply"; for example, the sealing rings of ordinary pipe fittings are mostly made of ordinary rubber, which hardens after a few years in the sun, the elasticity is gone, and the sealing effect is naturally poor. These are not "technical problems", but "the most urgent problems for users to solve" - after all, no one is willing to pay for "avoidable leaks". The matching pipe fittings of

AD pipeline are to focus on these "small pain points" to make innovation. The first is the "precise adaptation" of the structural design: for example, the socket pipe fittings are added with a circle of "positioning grooves". When the pipe is inserted to the bottom during construction, you will hear a "click" sound, and directly lock the optimal insertion depth - no longer need workers to measure with rulers or guess by feeling. This small design looks simple, but it solves the big problem of "virtual welding" during hot melt: the insertion depth is accurate, and the welding surface can be fully fitted. There will be no situation where "one side is welded and the other side is not glued".

Then there is the "upgrade" of the sealing material: the ordinary rubber sealing ring is replaced by ethylene propylene diene (EPDM). This material is particularly resistant to aging and high and low temperatures - after aging testing, it can maintain more than 85% elasticity in an environment of 80 ° C for 1000 hours, which is 30% higher than ordinary rubber rings. Even if buried in the ground for more than ten years, the sealing ring can still tightly "wrap" the pipeline and will not lose its sealing effect due to aging.

also has "adaptability optimization" of the connection process: for example, for the flexibility of PE coil, the entrance of the pipe fittings is "rounded", which will not scratch the inner wall of the pipe when inserted; the resistance wire of the electric fusion pipe fittings is arranged more evenly, and the heat can be transmitted from head to tail when powered on, and there will be no "local overheating burning". These details are not "high-tech", but make the "stability of the connection" to the extreme. How is the effect of

? Look at the actual project to know: in a rural safe drinking water project in a county in Zhejiang, the PE coil pipe with AD matching pipe fittings was used. After a stress test of 1.6MPa (equivalent to twice the normal water supply pressure), no connection point leaked within 24 hours; the construction party said that before laying a 1-kilometer pipeline, it would take 3 days to deal with the leak, but now it is not needed at all - "plug it in and click, you will know that there is no problem". There is also feedback from home improvement users. After installing the PE coil and pipe fittings of AD, it has been used for 5 years, and the kitchen water pipe has never leaked, saving a lot of worry.

In fact, the core of the connection problem of PE coil pipe is "pipe fittings and pipes should'fit together '". AD Pipeline does not engage in any "fancy" technology, but regards "user's trouble" as its own "research and development topic": the dimensional accuracy of the pipe fittings is controlled to within 0.1mm to ensure a tight fit with its own PE coil; the compression amount of the sealing ring has been tried hundreds of times, and it can just fill the gap without crushing the pipe; even the packaging is printed with "step by step to teach you to connect" guidelines, for fear that the workers will make mistakes.

For plastic pipes, "no leakage" is the most basic requirement, but it is also the most real word of mouth. The innovation of the supporting pipe fittings of the AD pipeline does not talk about the concept of "tall", but uses technology to plug the "place that would have leaked" - after all, solving the actual problems of users is the most effective way of technology.
