HART-PP-100
HART Industry
HART-PP-001
Wear Resistant Steel Pipe CCO Wear Pipe
HART Hardfacing Overlay Pipe is manufactured by depositing chromium-rich, abrasion-resistant materials on the mild seamless pipe or welding pipes, using a traditional arc welding process. The wear pipe is available with double or multiple overlay passes. And it can be fabricated as square-to-round transitions, elbows, T or Y- shaped.
The CCO pipe is designed with extreme wear capabilities for working in many applications: mining, cement, oil sands, dredging, recycling and steel production industries.With either a circumferential or longitudinal weld deposition.
Our company provide chromium carbide clad pipe are ideal for combatting abrasion either as gravitational feed pipes or as part of a pneumatic transfer system.

8. Microstructure:
Composed of a high proportion of extremely hard primary M7C3 chromium rich carbides dispersed in a ductile eutectic austenite matrix.
Maintains 30% to 50% of primary carbides to provide a good wear resistance and homogenous bonding.
9. Typical Applications:
HART-PP-100 Pipe is widely used in the mining, power generation(Coal), cement, dredging, steel production, waste handling, glass production, and pulp and paper industries. Some specific applications include:
| INDUSTRY | APPLICATONS |
| Mining | Slurry pumps, chutes |
| Cement | Slurry pumps, chutes |
| Dredging | Dredging pipes and pumps, suction pipelines, pump discharges |
| Steel | Suction pipelines, pump discharges, air ducts, carbon injection pipes, suction lines, troughs |
| Recycling | Cullet glass |
