[Case Study] Further Extension of the Lifespan of Wear-Resistant Rubber Hoses (Ceramic)!

Further extension of the lifespan of wear-resistant rubber hoses (ceramic bead hoses)!

In the raw material transport line that performs high-speed pneumatic conveying, there is a problem with the short lifespan of hoses, and we have adopted wear-resistant hoses with ceramic beads embedded in the inner surface. While the lifespan of the hose body has been significantly extended by 2 to 3 times, localized wear at the connection points with fittings has become an issue. Issues: 1. The rubber section with embedded ceramic beads is lined on the inner surface of the hose up to the fitting mouth, causing the conveyed materials to come into contact with the rubber lining cross-section. The inner diameter of the rubber lining with embedded ceramic beads is smaller than that of the existing piping. 2. The conveyed materials that come into contact wear against the rubber section behind the ceramic beads, causing the ceramic beads to detach and exposing the connecting fittings. As a result, the lifespan of the connection points has become significantly shorter compared to the hose body. 3. By increasing the wear resistance near the connecting fittings, it is possible to extend the overall lifespan of the hose.
