Abstract

Impressed Current Cathodic Protection (ICCP) adalah sistem perlindungan logam terhadap korosi dengan menggunakan sumber arus DC dari luar sistem. Kutub positif sumber arus DC dihubungkan dengan anode inert (grafit) sedangkan kutub negatif sumber arus DC dihubungkan dengan logam atau katoda yang akan dilindungi dari serangan korosi. ICCP digunakan karena sistem proteksi ini memiliki beberapa kelebihan diantaranya mudah untuk mengontrol arus proteksi, dapat memproteksi luasan yang cukup besar, mudah mendeteksi kerusakan pada sistem proteksi, dan dapat digunakan di berbagai macam jenis katoda dan lingkungan yang berbeda. Pada perancangan ini dilakukan desain ICCP pada katoda API 5L grade B dengan pemberian coating dan tanpa coating dengan kondisi lingkungan yang terus berubah. Pada pipa tanpa coating, arus yang diperlukan lebih besar dibandingkan dengan pipa coating, perubahan lingkungan membuat kondisi lingkungan berubah menjadi lembab dan kering maupun sebaliknya. Saat kondisi lingkungan basah, nilai resistvitas tanah menurun menyebabkan keperluan arus proteksi meningkat, sementara saat kondisi lingkungan kering, nilai resistivitas tanah meningkat menyebabkan keperluan arus proteksi menurun. ========================================================== Impressed Current Cathodic Protection (ICCP) is a system of metal protection against corrosion by using DC current source from outside the system. The positive pole of DC current source is connected to the inert anode (graphite) while the negative pole of the DC current source connected with metal or cathode to be protected from corrosion. ICCP has several advantages such as easy to control the current protection, had large surface area protection, easy to detect damage the protection system, and can be used in various types of cathodes and a different environment. The ICCP design used for cathode pipe steel API 5L grade B with coating and without coating therefore the environmental conditions continually changing. Pipe without coating indicates need huge current protection more than pipe with coating. The conditions of environmental changes from moist and dry and the reversed ,when conditions are wet, the value of soil resistivity is decrease, its led to the purposes of current protection increases, while conditions is dry, soil resistivity values increase causing the current protection is decreases
