    Study and analysis of corrosion protection process for petroleum pipelines by composite coating
    (Altınbaş Üniversitesi / Lisansüstü Eğitim Enstitüsü, 2024) Al-Safi, Saif Ayad Kareem; Alaiwi, Yaser
    The aim of this research is to conduct a comprehensive study of the Petroleum pipeline in general, using composite coatings that prevent corrosion. A section of an oil pipeline in the city of Basra in Iraq was chosen with a length of 3 meters, and the rest of the specifications come standard depending on the type of material and the amount of test pressure. In the beginning, a test will be conducted without any compound paint, and this is what is known as Baseline Design. Then the study will be conducted by placing an internal and an external composite Coates on the surface. Two materials will be used, 3-Layer-Polyurethane (3LPE) and fusion-bonded epoxy (FBE). A study will be conducted on each material separately and their results will be extracted completely, as two tests will be conducted, the first is structure Integrity test is used to ensure the integrity of the structure when exposed to very high pressure which is a test pressure or hydrostatic pressure. The other test is thermo-static structural test and will be conducted over a period of 15 years using the design pressure and temperatures of the city of Basra recorded over a year. The study proved that the use of composite coatings completely prevents corrosion and collapse of pipes in the very long term by looking at the safety factor as well as the life of the oil pipe.
