Overlay pipes for various wear applications
Duroxite® Pipe products are used for transporting slurry and other abrasive fluids that create sliding wear, for example in dredging. The pipes are made with a chromium-rich hardfacing layer deposited inside a mild steel pipe.
Matching Duroxite® pipes to your application
Duroxite® overlay pipes are classified so that the hardfacing material matches the type of application and wear environment.
SSAB Tech Support is happy to answer any questions you may have on the selection of Duroxite® hardfaced pipes.
