With the rapid development of the cold chain logistics industry, the medium transportation system in the low temperature environment has put forward extremely high requirements for pipeline performance. As a transit and storage hub for food, medicine and other products, the internal pipeline of the cold chain logistics park not only has to withstand the long-term effect of low temperature medium, but also needs to deal with frequent fluid impact and complex park layout. Therefore, it is crucial to choose a pipeline product that is both reliable and economical. HDPE steel mesh skeleton pipe has shown significant advantages in the application of cold chain logistics park due to its unique structural design and material characteristics, and has become an ideal choice for low temperature transportation system.

From the perspective of material characteristics, HDPE steel mesh skeleton pipe is composed of high density polyethylene (HDPE) substrate and steel wire reinforced skeleton. This structure not only retains the chemical corrosion resistance and anti-aging properties of HDPE materials, but also enhances the overall compression resistance through the internal steel wire skeleton. It can work stably in the temperature range of -40 ° C to 40 ° C, and is perfectly suitable for the low temperature transportation environment of the cold chain park. Compared with traditional PVC or ordinary PE pipes, its impact resistance in the low temperature environment is improved by more than 30%, which can effectively avoid the problem of pipeline rupture caused by temperature changes.

In terms of pressure resistance and bearing capacity, the transportation system of the cold chain logistics park often needs to simultaneously transport large flow of chilled water, refrigerant and other media, and the pipeline needs to withstand high internal pressure. The steel wire skeleton of HDPE steel mesh skeleton pipe adopts high-strength low-carbon steel wire. Through a special weaving process, it is closely combined with HDPE material, so that the pipe ring stiffness can reach more than 8kN/m2, which can meet the transportation needs of different pressure levels in the park. Whether it is overhead laying above the ground or underground laying with a large buried depth, its structural stability can be fully guaranteed, reducing the risk of pipeline deformation caused by external loads or soil pressure.

Corrosion resistance and environmental protection performance are also outstanding advantages of HDPE steel mesh skeleton pipe. In the cold chain environment, moisture in the air and trace chemicals that may be contained in the medium can easily cause rust to metal pipes. The HDPE material itself has excellent chemical stability, acid and alkali resistance and salt spray resistance, which can effectively resist the erosion of various media and prolong the service life of pipelines. At the same time, the product is made of environmentally friendly materials, does not contain heavy metal additives, and will not release harmful substances during long-term use, which meets the requirements of modern cold chain logistics for green environmental protection, and also avoids the risk of pollution to storage products.

The reliability of the connection method directly affects the sealing performance of the pipeline system. HDPE steel mesh skeleton pipe adopts electrofusion connection technology, and the pipeline and fittings are welded together through special electrofusion pipe fittings to form an overall sealing structure. The sealing performance of this connection method is better than that of traditional adhesive or socket connection. It can still maintain good stability in low temperature environment and effectively reduce the risk of medium leakage. In addition, the electrofusion connection process is simple, the construction is convenient, and it can adapt to the complex pipeline direction and installation space restrictions in the park, shorten the construction period and reduce labor cost investment.

From the perspective of long-term economy, the service life of HDPE steel mesh skeleton pipe can reach more than 50 years, which is 3-5 times that of ordinary pipes. Its excellent weather resistance and corrosion resistance can greatly reduce the maintenance frequency and replacement cost of pipelines in the park. Taking the HDPE steel mesh skeleton pipe of AD Pipeline as an example, its application data in actual cold chain projects shows that compared with the traditional pipeline system, it can reduce the maintenance expenditure by more than 30%, and the comprehensive benefits are significant. At the same time, the pipeline is light in weight and convenient in transportation, which further reduces the comprehensive cost of the project.

To sum up, HDPE steel mesh skeleton pipe plays a key role in the low temperature medium transportation system of the cold chain logistics park by virtue of its core advantages such as low temperature resistance, high pressure resistance, corrosion resistance and long life. As a leading enterprise in the pipeline industry, the production of HDPE steel mesh skeleton pipes strictly follows industry standards, and through refined production technology and strict quality control, each pipeline can meet the complex application scenarios of the cold chain logistics park.
