Conclusions
-
1.
The temperature and pH of the corrosive solution determine, while mineralization and the flow rate of the corrosive solution have no effect on, the gas-abrasive wear of alloys AT3 and AT6.
-
2.
Wear is negligible in alkaline and neutral solutions at room temperature; intensive wear of both alloys is observed after treatment in acid solutions (pH<4) at high temperatures (250°).
-
3.
Alloy AT3 has higher corrosion and gas-abrasive resistance than AT6. Both alloys are recommended for drill pipe in deep wells.
