Abrasion Resistant Ceramic Lined Hose Corrosion Impact Proof Custom Sizes
Ultra Wear Resistant Slurry Hose
Engineered for high-abrasion slurries (e.g., mining tailings, coal ash), this hose integrates ZTA (zirconia-toughened alumina) ceramic tiles with a natural rubber backing for impact absorption. The interlocking tile design prevents material ingress at joints, achieving 3x longer service life vs. standard rubber hoses. Handles solids content up to 80% and pH 1-14. Pressure rating: 10MPa static, 6MPa dynamic. Available with conductive layers for ATEX Zone 1 compliance.
