Measures Improving Freezek-thaw Resistance and Abrasion Resistance of Concrete Pavement

Study on erosion-resistance of the flexible organic coating composite;

Based on data review, the corrosion and erosion of metal drilling tools in under-balanced drilling are analyzed, including affecting factors, composition and application of corrosion inhibitors.

The analysis shows that the erosion happens in the oil refining activator slurry pump,the treatment to resisting erosion of the pump impeller,prolong efficiently the running period of this pump.

But for those turbines in silt-laden river, because of the wear by sediment and the interaction between the wear and cavitation, the setting height of turbine would influence the investment and safe and stable operation of the hydropower station.

Study on New-style Sealing Structure for Anti-abrasion and cavitation;

The water flow with silt have stronger destructive power to the abrasion and cavitation of the through-flow parts of the water turbine.

Experiment Study of Anticorrosive-wear about Tube and Rod Friction Pair in the Pumping Well;

Experimental study on electrode potential and electrochemical corrosion of four kinds of ordinary materials selected under different sewage environments was discussed,in order to ascertain the influence of electrochemical corrosion on corrosive-wear of oil tube and pumping rod.

Study the corrosive-wear rules of the oil tube and pumping rod in different environment can guide technologists through the selection of the suitable tube and rod materials.
