Abstract

Air laut mengalir melalui pompa balas, pipa utama pada sistem balas, dan pipa cabang pada sistem balas. Karena air laut adalah cairan alami yang paling korosif dan sistem balas membutuhkan banyak penggunaan air laut, risiko terkena korosi sangat tinggi. Oleh karena itu, pelindung korosi diperlukan untuk membuat sistem berfungsi secara efisien. Di dunia pelayaran sangat tergantung pada material besi baja untuk kebutuhan kapal terutama untuk pipa balas. Penelitian ini bertujuan untuk mengetahui ketahanan korosi dengan spesimen pipa baja karbon, pipa baja karbon dengan lapisan epoksi, dan pipa baja karbon galvanis dengan metode elektrokimia. Hasil laju korosi menunjukkan perbedaan pada setiap waktu perendaman. Ada 2 kali perendaman untuk masing-masing spesimen percobaan 72 jam dan 144 jam. Untuk perendaman 72 jam pada spesimen pipa baja karbon adalah 0,194746712 mmpy dan selama 144 jam adalah 0,28611955 mmpy. Perendaman spesimen pipa baja karbon dengan lapisan epoksi selama 72 jam adalah 0,018398877 mmpy dan selama 144 jam adalah 0,0190332 mmpy. Dan spesimen pipa baja karbon galvanis selama 72 jam perendaman adalah 0,001825366 mmpy, untuk 144 jam adalah 0,001971516 mmpy. ======================================================================================================= The seawater is flowing through ballast pumps, main pipelines, and branch pipes. Because of seawater is the most corrosive natural fluid and ballast needs a lot of seawater usage, the risk of corrosion is very high. Therefore, the protective for corrosion is needed to make the system function efficiently. In the shipping world is highly dependent on the steel metal material for the needs of the ship especially for the ballast pipe. This bachelor thesis aims to determine the corrosion resistance with specimen carbon steel pipe, carbon steel pipe with epoxy coating, and galvanized carbon steel pipe with electrochemical method. The result of the corrosion rate shows the difference on each immersion time. There are 2 times immersion for each experiment specimen 72 hours and 144 hours. For immersion 72 hours of Specimen carbon steel pipe is 0.194746712 mmpy and for 144 hours is 0.28611955 mmpy. The immersion of specimen carbon steel pipe with epoxy coating for 72 hours is 0.018398877 mmpy and for 144 hours is 0.0190332 mmpy. And for the galvanized carbon steel pipe for 72 hours immersion is 0.001825366 mmpy, for the 144 hours is 0.001971516 mmpy.
