Durability Enhancement of Nano Woven Surfaces in Pneumatic Conveying Pipes: Material Innovation and Structural Design

Introduction: Pipeline wear is a critical issue in pneumatic conveying systems, where high-speed particulate-laden airflow causes wall friction and impact, leading to material loss, thinning, and perforation. This review introduces nanotechnology-reinforced strategies to enhance pipeline wear resistance, including nanocomposite applications, surface nanotexturing, structural optimization, and nanofunctional coatings. The objective is to mitigate wear and extend service life via nanotechnology-based structural and surface engineering, thereby improving system safety and efficiency. Methods: Key methods involve fractal-scale texture and composite insulation layers for integrated performance, alongside laser biomimetic multiscale surfaces modified with nanomaterials. Results: Results demonstrate reduced fluid resistance, heat transfer, and energy loss, with biomimetic structures significantly lowering abrasion rates through impact dispersion, anti-adhesion, and self-cleaning effects. Discussion: Although the synergistic effects of the above-mentioned nanotechnology and bionic design have demonstrated significant advantages at the laboratory level, it is necessary to balance technical costs and life cycle benefits in actual industrial applications. Conclusion: This review presents innovative nanotechnology and biomimetic design solutions for optimizing pneumatic conveying systems, offering valuable engineering insights.
