Using wear-resistant pipe surfacing machine, adopting open-arc self-protection automatic surfacing welding technology on the inner wall (above 80mm in diameter) or outer wall (unlimited diameter) of seamless steel pipe (Comply with GB / T8163-1999).
Common thickness of steel pipe inner wall surfacing layer: 3-6MM.
The thickness of the outer wall surfacing layer can be customized according to customer requirements.
Operation method: open arc welding
Hardness range: HRC55-62
Normal thickness(mm): 6 + 4/ 8 + 4/ 10 + 8
Pipe length: 50-3000mm, accept size customization
Chemical composition：
Cr | C | Si | Mn | Other |
15-30% | 4-5% | 0.5%-1.5% | 0.5%-2.5% | ≤2% |
The Chromium carbide wear resistant pipe not only has high abrasion resistance、high temperature resistance、impact resistance and vibration resistance, but also has good toughness. Easy to connect by welding or flange and bolt.
