Jianlong brand HDPE water supply pipes: a reliable choice for water supply projects. These advantages and key construction points are a must-read!

Its corrosion and aging resistance are also noteworthy. HDPE itself is an inert material, capable of withstanding most chemical media except for a few strong oxidants. Unlike metal pipes, it won't experience electrochemical corrosion, making it particularly reliable for industrial raw material transportation. Furthermore, the pipe contains 2%-2.5% evenly distributed carbon black, which resists UV damage even when stored or laid outdoors, preventing it from becoming brittle and aging after just a few years—its lifespan is significantly longer than ordinary pipes.

For urban water supply, "green and environmentally friendly" is crucial. This pipe is manufactured without any heavy metal stabilizers, is non-toxic, and has a smooth inner wall that prevents scaling and bacterial growth. Secondary pollution is a major threat to urban drinking water safety; choosing this environmentally friendly pipe is like adding a "safety lock" to residents' water supply. In addition, its inner surface Manning coefficient is only 0.009, much smoother than traditional pipes, resulting in lower flow resistance, stronger transport capacity, and reduced energy consumption during water delivery, saving considerable operating costs in the long run.

Connection reliability is also not a concern. HDPE water supply pipes are mainly connected using heat fusion or electrofusion. The joint strength is even higher than that of the pipe itself, and the joint will not break even if the soil moves or external loads occur. When laying pipelines in industrial parks, many sections were driven over by vehicles. After using heat fusion, the joints remained very stable and there were no leakage problems.

Let's talk about application scenarios. This pipe has a wide range of applications: it can be used for urban water supply system renovation, industrial raw material transportation, urban functional construction, agricultural irrigation, and even ground source heat pump water pipelines. It can be called a "jack-of-all-trades". Whether it's a municipal project or an industrial project, as long as water transportation is involved, choosing this pipe is generally a safe bet.

Finally, I'd like to share a few key construction points, as even good pipes need proper installation to fully realize their advantages. If using heat fusion connection, pay attention to these steps: the cut end face of the pipe must be flat and free of impurities; the misalignment during alignment should not exceed 10% of the wall thickness; the heating temperature should be controlled between 210-230°C, with a melting length of 1-2mm being ideal; after switching heating plates, quickly connect the pipes, maintaining pressure to achieve a crimp width of 2-4mm; during cooling, do not touch the joint until the crimp feels hard and no longer warm to the touch before releasing the clamps.

If connection to steel pipes or valves is required, use steel-plastic flanges. Butt-weld the HDPE pipe end to the plastic support ring using heat fusion, and weld the flange to the steel pipe end according to specifications. For large sizes or high-pressure applications, remember to add sealing rings. When using electrofusion connections, first check the fittings for broken threads. After inserting the pipe, ensure it is fully in place and secured. Strictly adhere to the manufacturer's welding parameters. Do not move the clamps before cooling. After completion, check for any molten material leakage and ensure the resistance wire is not exposed.

In summary, Jianlong brand HDPE water supply pipes have stood the test in terms of both performance and practicality, making them a cost-effective choice for both engineering procurement and construction.
