With the growth of urban population and the expansion of industrial scale, the fields of drainage, water supply, and industrial medium transportation have put forward higher requirements for the transportation capacity of pipelines - not only to be able to transmit media efficiently, but also to operate stably for a long time. Under such demand, AD HDPE carat pipe has become a high-quality solution to improve pipeline transportation capacity by virtue of its unique structural and material advantages.

AD HDPE carat pipe adopts a hot winding molding process to form a unique hollow wall structure. This structure not only allows the pipeline to have excellent ring stiffness (compressive resistance), but more importantly, its inner wall maintains the smooth characteristics of HDPE material itself - the roughness of the inner wall is only 1/10 of that of steel pipe and 1/20 of that of concrete pipe. The smooth inner wall can greatly reduce the frictional resistance when the medium flows. According to the principle of hydrodynamics, under the same pipe diameter, the higher the smoothness of the inner wall, the faster the medium flow rate and the greater the conveying flow rate. For example, in the municipal drainage scene, the actual conveying capacity of the same diameter AD HDPE carat pipe can be increased by 20% to 30% compared with the traditional concrete pipe, effectively relieving the drainage pressure in the rainy season.

In addition to the structural advantages, the characteristics of the HDPE material itself also add points to the conveying capacity. HDPE is a high crystallinity thermoplastic resin with excellent chemical corrosion resistance - whether it is acidic, alkaline or saline media, it will not cause corrosion or scaling to the inner wall of the pipeline. After the traditional metal pipe or concrete pipe is used for a period of time, the inner wall is easy to scale and rust, resulting in smaller pipe diameter, increased resistance, and reduced conveying capacity; while the inner wall of the AD HDPE carat pipe remains smooth after long-term use, and the conveying capacity is almost not attenuated. It is especially suitable for the conveying of corrosive media such as industrial wastewater and chemical raw materials.

In practical applications, the conveying advantages of the AD HDPE carat pipe have been fully verified. For example, in a municipal drainage project in a southern city, the original concrete pipe used due to the scaling of the inner wall caused the drainage capacity to decrease by 30%. After replacing it with the AD HDPE carat pipe, not only the original design flow was restored, but also the conveying capacity was increased by an additional 15% due to the smooth inner wall, which completely solved the problem of waterlogging in the rainy season In an industrial scenario, a chemical company used AD HDPE carat pipes to transport acid-containing wastewater. After 3 years of operation, the test showed that the inner wall of the pipeline was non-corrosive and non-scaling, and the transportation flow maintained more than 98% of the initial state.

improves the pipeline transportation capacity, not simply increasing the pipe diameter - but optimizing from multiple dimensions such as material, structure and long-term stability. Through the combination of "smooth inner wall + corrosion-resistant material + high-strength structure", AD HDPE carat pipes not only solve the pain point of "transportation efficiency attenuation" of traditional pipelines, but also meet the long-term operation needs of different scenarios. Whether it is "rapid drainage" of municipal drainage or "stable transmission" of industrial transportation, it can become a reliable choice to improve transportation capacity.
