Chromium carbide overlay wear resistant tube is on the inner wall (more than 80mm in diameter) or outer wall (unlimited diameter) of ordinary steel pipes, the open arc self-protection automatic surfacing process is adopted, and the wear-resistant pipe surfacing machine is used to automatically and seamlessly overlay a layer of high abrasion resistance (or High corrosion resistance) alloy material.
Common thickness of steel tube inner wall surfacing layer: 3-6MM.
The thickness of the outer wall surfacing layer can be customized according to customer requirements.
Production process: open arc welding
Hardness range: 50-62HRC
Common specifications: 5 + 3/6 + 4/8 + 5/10 + 8, etc.
Pipe length: 50-3000mm, accept size customization
Chemical composition of the chromium carbide overly wear resistant tube:
Cr:18-30% C: 4-5% Si:0.5% -1.5% Mn: 0.5% -2.5% Other: ≤2%
Pipeline performance :
