Large diameter sandblasting hose is an important equipment widely used in engineering construction and industrial production. It has larger diameter pipes and special sandblasting materials, which can be used to spray hard particles onto the surface of the workpiece to achieve cleaning, remove stains, and increase roughness. In many fields, large-diameter sandblasting rubber pipes are widely used, such as ship repair, bridge anti-corrosion, steel structure spraying, etc. One of the characteristics of large-diameter sandblasting hose is its larger pipeline diameter, which allows it to handle larger sandblasting particles. This means that during the sandblasting process, hard particles can be more efficiently projected onto the surface of the workpiece. In addition, due to the large diameter of the pipeline, the sandblasting hose has a higher spraying speed and a larger spraying range, which improves work efficiency. Another noteworthy feature is that the large-diameter sandblasting hose can use multiple sandblasting materials. According to different job requirements, different types of sandblasting materials can be selected, such as quartz sand, glass particles, or steel balls. These sandblasting materials have different hardness and particle sizes, and the working parameters of the sandblasting hose can be adjusted as needed to achieve varying degrees of cleaning and surface treatment effects. In order to ensure the normal operation of large-diameter sandblasting rubber pipes, their design and manufacturing must meet high standards of quality requirements. Firstly, the sandblasting hose must have good pressure resistance and corrosion resistance to meet various working conditions in engineering construction and industrial production. Secondly, the sandblasting hose should also have good sealing performance to avoid particle leakage and gas loss. Finally, the sandblasting hose should have the characteristics of easy installation and maintenance to facilitate user operation and maintenance. In summary, as an indispensable equipment in engineering construction and industrial production, large-diameter sandblasting rubber pipes play an important role in improving work efficiency and product quality. By selecting appropriate sandblasting materials and controlling working parameters, large-diameter sandblasting hoses can meet the requirements of cleaning, decontamination, and increasing roughness. In future development, we have reason to look forward to the application of large-diameter sandblasting hose in more fields and further technological innovation.
