Urban water supply systems are crucial infrastructure for ensuring residents' daily lives and the normal operation of a city. In a large municipal water supply project, the efficient and high-quality production of large-diameter pipe materials that meet project requirements has become a key aspect of project construction. Screw extrusion units, with their superior performance, have stood out in this project, providing solid technical support for its smooth progress.

This large municipal water supply project aims to enhance the city's water supply capacity and improve residents' water quality. The project plans to lay a large number of large-diameter water supply pipes, which will undertake the water supply tasks for the city's main areas, placing extremely strict requirements on the quality and dimensional accuracy of the pipe materials. Traditional production equipment often struggles to meet the demands of such large-scale, high-precision pipe material production tasks, failing to satisfy the project's schedule and quality requirements.

The screw extrusion unit demonstrated strong technological advantages in this project. First, it possesses powerful extrusion pressure. The production of large-diameter pipe materials requires a large amount of plastic raw material to be extruded uniformly in a short time, ensuring the density and strength of the pipe material. By optimizing the screw structure and drive system, the screw extrusion unit can generate sufficient extrusion pressure, allowing the plastic raw materials to be fully plasticized and quickly extruded in the barrel, forming the required pipe material billet. Tests show that this unit can stably produce large-diameter pipe materials with a diameter of up to [X] meters, meeting the project's special requirements for pipe material dimensions.

Precise mold control technology is another highlight of the screw extrusion unit. In the pipe material production process, the mold directly determines the dimensional accuracy and surface quality of the pipe material. The unit is equipped with an advanced mold control system that can monitor the mold's temperature, pressure, and other parameters in real-time and automatically adjust them according to the production situation, ensuring the stability of the mold throughout the production process. Through this precise control, the produced large-diameter pipe materials have uniform wall thickness, with errors controlled within a very small range, fully meeting the project's strict engineering standards. This not only ensures the compressive strength and sealing performance of the pipe materials during use but also significantly improves their service life, laying the foundation for the long-term stable operation of the urban water supply system.

In addition, the screw extrusion unit has a high degree of automation, achieving continuous operation of the production process. From the feeding, plasticization, and extrusion of plastic raw materials to the cooling and cutting of the pipe materials, the entire process is controlled by an automated system, reducing manual intervention, improving production efficiency, and lowering production costs. During project implementation, the screw extrusion unit operated continuously for 24 hours, producing a large number of large-diameter pipe materials daily, effectively shortening the project's construction cycle and ensuring that the municipal water supply project could be completed and put into use on time.

The project manager stated: “The screw extrusion unit played a vital role in our large municipal water supply project. Its efficient and precise production capabilities allowed us to complete the production of a large number of large-diameter pipe materials on time and to the required quality. These high-quality pipe materials are the ‘lifeline’ of the urban water supply system, and their successful delivery provided reliable assurance for the successful implementation of the entire project. We are very grateful to the R&D team and manufacturer of the screw extrusion unit; their technological innovation has made significant contributions to urban infrastructure construction.”
