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), a layer of high wear-resistant or high corrosion-resistant alloy material is automatically and seamlessly welded by the CNC to form chromium carbide alloy wear-resistant pipe.
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
