摘要

研究了流量和温度对热电厂冷凝液中碳钢管腐蚀速率的影响。在本研究中，电化学测量强调了腐蚀速率。电化学测量在静止和动态两种条件下进行。本研究中使用的温度有三种:30oC, 40oC和50oC。对安装在动态工况下的腐蚀池进行改造，流量变化:0.27 m/s;0.6米/秒;1米/秒;1.5米/秒;1.9 m/s。研究发现，热电厂冷凝液中腐蚀速率随温度和流体流量的增大而增大。在50℃和1.9 m/s的流速下，腐蚀速率最高(38 mpy)。

EFFECT OF FLOW RATE AND TEMPERATURE ON CORROSION RATE OF CARBON STEEL PIPE IN CONDENSATE SOLUTION FROM GEOTHERMAL POWER PLANT

The research aims to study the effect of flow rate and temperature on corrosion rate of carbon steel pipe in condensate solution from geothermal power plant. The corrosion rate in this study highlighted by electrochemical measurement. Electrochemical measurement performed in two conditions i.e stagnant and dynamic conditions. There are three kinds of temperature used in this research : 30oC, 40oC, and 50oC. Modification of corrosion cell installed for dynamic condition with flow rate variations : 0.27 m/s; 0.6 m/s; 1 m/s; 1.5 m/s; and 1.9 m/s. It was found that corrosion rate boosts with temperature and fluid flow rate in condensate solution of geothermal power plant. The highest corrosion rate (38 mpy) obtained at 50oC and 1.9 m/s of flow rate.
