In high-wear industrial scenarios such as cement, mining, thermal power, metallurgy and chemical industries, conveying pipelines are continuously subjected to severe scouring by sharp media including mineral sand, coal powder and furnace slag. Even with thickened steel plates or surfacing treatment, traditional metal pipelines still suffer from abrasion perforation, frequent replacement and repeated shutdown maintenance. The resulting leakage risks, reduced production efficiency and soaring maintenance costs have become invisible cost killers that restrict stable industrial production.
