Abstract
Kariangau industrial complex (KIK) is an industrial area located in Balikpapan. Many establishments in KIK are companies providing support for the mining, oil and gas industry. Indeed, for KIK to expand, the companies will build infrastructure both above and underground. For underground structure, either it is a pipeline installation, structural foundation, or buried structure, all will be at risk to degrade by corrosion. This study aims to provide a brief overview of corrosion risk in buried structure or pipeline in KIK. In this research, 5 points of reference chosen to represent different soil conditions in KIK and material used is API 5L to represent the structure of a pipe used in gas industries. The observation conducted on the soil condition and material to analyse the corrosion behaviour in KIK. The result shows that KIK has low corrosion risk and complex corrosion behaviour. Some areas have different corrosion behaviour than others, and the condition can be dynamic to time. It is recommended to use this article wisely for engineers to use this article for corrosion engineering in this area.
