On the inner wall of the seamless steel pipe (diameter above 80mm) or the outer wall (the diameter is not limited), the open arc self-protection full-automatic surfacing welding process is adopted, and the wear-resistant tube surfacing machine is used, and the CNC automatically surfacing a layer of high wear resistance alloy.
Common thickness of surfacing layer on inner wall of steel pipe: 3-6MM.
The thickness of the outer wall surfacing layer can be customized according to customer requirements.
Production process: open arc welding.
Hardness range: HRC55-62.
Installation method: welding, flange
Mainly used: mine fillings, refined powder and tailings transportation, Pulverized coal and coal slag delivery, ash transportation, etc.
