“…Spontaneous physicochemical destruction and premature failure of the coiled-pipes of the tubular furnaces at oil refineries, leading to irretrievable loss of their alloys, due to their chem ical or electrochemical interaction with the flowing crude oil can be defined as corrosion. As a result of the corrosion processes, the inner surface of the coiled-pipes is visibly destroyed (Saakyan et al 1982, Isaev1997 & Goldobina et al 2019, Ivanik et al 2017. A large amount of crude oil as well as natural gas is lost annually from through defects and the premature failures in oil-and/or gas-pipelines and coiled-pipes of tubular furnaces, which leads to envir onmental pollution, emergency situations, oil and/or gas shortages to consumers, and penal ties (Bakesheva et al 2019).…”
