Case Overview
A mineral-processing contractor replaced slurry pipelines every 6-9 months because of combined abrasion and corrosion, shutting down the line each time. The contractor wanted a wear-protection strategy: wear-resistant pipe where feasible, overlay protection for existing lines, and documented material properties supporting service-life calculations.
DZX qualified by supplying slurry pipes and overlay welding wire with complete chemistry and application documentation, supporting the contractor’s life-extension program toward a 24-month service target.
This case summarizes the application requirements, materials supplied by DZX and delivery value. For case-specific technical data, please contact our engineering team.

Our Solution
The contractor’s wear-protection project faced three material challenges:
- Abrasive and corrosive slurry: combined mechanical abrasion and chemical attack wore through carbon-steel lines in 6-9 months, with each failure causing a pipeline shutdown.
- Overlay quality: protective overlays had to be dense and defect-free, with documented chemistry for consistent wear resistance.
- Life calculations: documented material properties were needed to justify overlay and replacement decisions.
DZX built a complete wear-protection package around the contractor’s service-life target:
Slurry pipes were supplied in stainless and corrosion-resistant grades with documented wall thickness for life estimates. Overlay and wear-protection wire was matched to the application, with verified chemistry for dense, wear-resistant deposits. Hydrometallurgical materials covered leaching and process lines. Each batch included chemistry and dimensional documentation supporting the contractor’s service-life calculations.
