Duroxite 100 Pipe

Duroxite 100 Pipe is manufactured by depositing chromium-rich, abrasion-resistant materials on a mild steel base using a traditional arc welding process. The hardfacing overlay pipe is designed with extreme wear capabilities for working in the most severe environments. Duroxite 100 Pipe is available with double or multiple overlay passes. Schedule 40 and Schedule 80 steel pipe as well as tubing can be hardfaced. Overlay Pipe can be fabricated as square-to-round transitions, elbows, T or Y-shaped, or as long sweeps.

 

Key Benefits

  • Same wear resistance guaranteed from surface down to 75% of the overlay
  • Optimal carbide composition to provide good combination of wear resistance and homogenous bonding

 

Typical Applications

Duroxite 100 Pipe is widely used in the mining, cement, oil sands, dredging, recycling and steel production industries.
Some specific applications include:

  • Mining, Cement, Oil Sands: Slurry pumps, chutes
  • Dredging: Dredging pipes
  • Recycling: Cullet glass
  • Steel: Air ducts, carbon injection pipes, suction lines, troughs

2) ASTM G65 is a standard test measuring sliding abrasion resistance using a dry sand/rubber wheel apparatus. ASTM G65-Procedure A is the most severe test method.
3) ASTM G65 wear test is conducted at 75% depth of the overlay materials to ensure consistently good wear resistance from the top surface through to the depth of 75% of the overlay.

The microstructure of Duroxite 100 Pipe is composed of a high proportion of extremely hard primary M7C3 chromium-rich carbides with a typical hardness of 1700 HK4) dispersed evenly in a ductile eutectic austenite matrix. The volume fraction of primary carbides is maintained between 30 to 50% to provide a good combination of wear resistance and homogenous bonding. 

4) HK is the Knoop microhardness used primarily for very brittle materials.
