Our company adopt open-arc self-protection automatic surfacing welding technology weld a protecting layer on the inner wall (above 80mm in diameter) or outer wall (unlimited diameter) of seamless steel pipe, the steel pipe comply with GB / T8163-1999. The layer includes high wear-resistant or high corrosion-resistant alloy material, and is automatically and seamlessly welded by the CNC.
Thickness of inner wall surfacing layer: 3-6MM.
Thickness of outer wall surfacing layer: accept customization.
Operation method: open arc welding
Hardness : 55-62HRC
Normal total thickness(mm): 6 + 4/ 8 + 4/ 10 + 8
Length: 50-3000mm, accept size customization
Chromium carbide overlay chemical composition：
The wear resistant chromium carbide overlay pipe not only has all advantage, but also easy to connect by welding or flange and bolt.
