“…Saltwater contains more dissolved ions than other types of water and this is the main reason why corrosion is greater in materials in contact with water (Lalli & Parsons, 1993) [9] . Due to the difference in salinity, the composition of salt water is different in each part of the world (Pinet 1996 [10] , Tavares et al, 2016 [11] ). This property can be correlated to its corrosion potential.…”

This paper is a literature review of coatings that aim to reduce corrosion in metallic pipelines that are in contact with saltwater. Among the existing coatings, the most common and ecologically available ones are: asphaltic enamel (AE), epoxy resin, Fusion Bonded Epoxy (FBE), Neoprene and multilayer coatings (polyethylene-PE, polypropylene-PP and polyurethane-PU). Due to the need by the industries, new technologies in this field are being developed. Carbon nanotubes, DLC (diamond type carbon), and self-recoating coating are some of the new coatings that are in evidence due to their hydrophobic property. There are many industrial applications that require high resistance to saltwater corrosion, such as coastal factories, onshore and offshore platforms, tidal power plants, and water desalination, which justify researches of new technologies in this area.

“…The EDS analysis in Figure 6 (a1 and b1) suggests that the main corrosion products consist of the elements: C, O, Fe, S, Ba, Si, Cl and Ca. The micrographs in Figure 6 [35][36][37] . Figure 7 presents the analysis by X-ray diffraction of the corrosion products formed on the surface of API 5L X80 steel coupons from the biotic and abiotic systems.…”

High-strength low-alloy steel is used in pipelines, which transport oil/gas and also produced water in the process of the secondary recovery of oil. This paper investigates the corrosion of X80 steel after immersion in static systems (biotic and abiotic). The corrosion rate, the corrosion morphology and the hardness of the coupons were investigated. The corrosion products were determined by SEM/EDS and XRD. The corrosion rates of the coupons in the biotic system were moderate and had an agressive pit morphology, while those of the coupons in the abiotic system were low with less aggressive pit. The hardness of the coupons after exposure to the systems of produced water was not changed compared with that of the control coupons. The corrosion products formed in the biotic system were Fe(OH) 3 , Fe(OH) 2 , FeOOH, Fe 3 O 4 , FeS 2 , FeCl 3 , and in the abiotic system, NaCl, CaCl 2 and SrSO 4 . BaSO 4 and CaCO 3 were identified in both systems.

“…Corrosion failure is more likely to generate in weld joint, on account of its drastic changes of ingredient, microstructure and property [11][12][13][14][15][16]. And many researches on corrosion behavior and mechanism of weld joint of pipeline steel have been carried out in laboratory by domestic and foreign scholars [17][18][19][20][21]. Kato et al explored the corrosion behavior of weld joints of carbon steel in a seawater and found that MnS inclusion, which formed during weld process, could improve the local corrosion sensitivity of weld tissues.…”

In this paper, the corrosion behavior of X80 pipeline steel weld joints in an acidic red soil solution was studied. The results show that uniform corrosion occurs on the entire surface of the weld joint after 840 h immersion. The corrosion degree of heat affected zone (HAZ) is more serious than that of base metal (BM) and weld zone (WZ). The corrosion rate of HAZ specimen is always higher than those of WZ and BM specimens throughout the separated immersion. The accelerating corrosion of HAZ may come from its microstructure change, its corrosion sensitivity and the deterioration of mechanical performance of corrosion product on it. OPEN ACCESS RECEIVED
