【 摘 要 】

In Center Port Nilam there is a construction of storage tanks and pipelines that will be used for the distribution and storage of Crude Palm Oil (CPO). CPO will be transported to the storage tank through a pipeline using carbon steel A53 grade B. In the pipeline there is a pipe bride as high as 8.6 meters, and under the pipe bride, there is an elbow that has the potential to erosion corrosion. The experiment is to test the effect of flow rate and temperature to the corrosion-erosion rate of CPO in elbow material of carbon steel A53 grade B. For calculations use the DNV RP O501 standard and for testing using the ASTM G31-72 standard. This research use variation of the fluid speed of 1 ms, 2 m/s, 3 m/s and temperature of 40°C, 50°C, 60°C. From the results using manual calculations for the flow rate of 1 m/s, 2 m/s, 3 m/s erosion corrosion rate successively is 0.0030 mmpy, 0.0440 mmpy, and 0.1946 mm / year. The erosion-corrosion rate successively is 0.0315 mmpy, 0.0450 mmpy and 0.0531 mmpy for flow rate of 1 m/s, erosion corrosion rate of 0,0596 mmpy, 0,0781 mmpy, 0,0950 mmpy for flow rate of 2 m/s and 0.1044 mmpy, 0.1274 mmpy and 0.1497 mmpy for flow rate of 2 m/s for the test results using testing method at a temperature of 40 °C, 50 °C, 60 °C. It can be concluded that the greater flow rate and temperature can lead to greater erosion corrosion rate.
