ABSTRACT
Corrosion is the gradual destruction of materials (primarily metals) caused by chemicals or chemical reactions with their environment. There is a natural tendency for almost all metals to react with their environment. As with earthquakes, corrosion of oil and gas production facilities is an expensive and harmful phenomenon that threatens human health, the ecosystem, and processing facilities. Since corrosion can pose a threat to the safety of oil and gas facilities, this chapter focuses on the types of corrosion that can occur. This chapter explains the basic principles of corrosion, which consists of four elements: anode, cathode, electrolyte, and metallic path. This book divides corrosion types into internal and external types. In this chapter, we discuss types of internal corrosion such as carbon dioxide, hydrogen sulfide, pitting, crevice corrosion, and chloride stress cracking. Additionally, external corrosion types that typically occur in offshore environments or underground are also considered.
