“…Protective iron carbonate layer often breaks down because of high velocity stream and stresses. In this case, carbonic acid results in localized corrosion under the name "mesa" corrosion because the shape of the damage of the steel surface is similar to the shape of the mountains "Mesa", California, USA [5]. The following methods of prevention of sweet corrosion are used: injection of corrosion inhibitors (they are not effective at high temperatures); use of martensitic stainless steels (>12% Cr); and control pH by caustic injection.…”

“…Carbon steel occupies more than 90% of all the materials in natural gas systems. Drill pipes are used according to the standard API 5D, casings and tubes -API 5CT, and linepipes -API 5L [5]. Design of carbon steel use should be made with calculation of corrosion allowance [32] and suitable heat treatment.…”

“…Erosion corrosion is ranked as the 5th most common degradation issue in fluid handling systems (pumps, compressors, piping systems in offshore oil/gas facilities, desalination plants, etc.) and has direct consequences in terms of equipment safety [2][3][4][5][6]. This problem gets more aggravated by the presence of high amounts of solid/sand particles of different morphologies in the flowing fluid [7,8].…”

Erosion corrosion performance of API 5L-X65 carbon steel was investigated at three different impingement velocities (3, 6 & 12 m/s), five different angles (15, 30, 45, 60, & 90 • ), and with/without solid particles (average particle size of 314 µm). The experiments were conducted in 0.2 M NaCl solution at room temperature for a duration of 24 h and the results showed that the maximum erosion corrosion rate was observed at 45 • irrespective of the velocity. The highest erosion corrosion rate at 45 • was due to the balance between the shear and normal impact stress at this angle. Ploughing, deep craters, and micro-forging/plastic deformation were found to be the main erosion corrosion mechanisms. The maximum wear scar depth measured using optical profilometery was found to be 51 µm (average) at an impingement angle of 45 • .

“…The choice of X80 steel was motivated by its widespread application in construction of casings, tubing, pipe works and transport lines in the oil and gas industry. [8][9][10][11][12][13][14] On the other hand, the choice of Griffonia simplicifolia is due to the broad alkaloid composition which has been reported about the plant, especially the presence of 5-hydroxytryptophan. …”

Different solvents were used to extract Griffonia simplicifolia and tested corrosion inhibitors for as X80 steel in 1 M HCl solution. The corrosion tests were conducted by thermo-gravimetric analyses (TGA), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PDP) while the surface morphologies were checked by scanning electron microscopy (SEM). The essence was to investigate the effects of the solvents on the yield, phytochemical profile, corrosion inhibition properties and thermal stability of the extracts. The highest yields of 63.24 g kg -1 and 51.63 g kg -1 were obtained with seeds (SEGS) and leaves (LEGS) extracts respectively in ethanol-water (1:1) system. Acetone extract showed presence of all the tested phytochemicals namely alkaloids, tannins, saponins, glycosides, steroids and terpenoids. The highest inhibition efficiencies of 95.86 % (SEGS) and 82.14 % (LEGS) were obtained with acetone extracts. Acetone extract was also most thermally stable being 66.4 % (SEGS) and 50.05 % (LEGS) efficient at 90 C, followed by ethanol extract while methanol extract was least stable and least efficient. Inhibitors act as mixed type and their addition increased charge transfer resistance and decreased corrosion current density with respect to the free acid solution. Micrographs of the steel surface in some systems show evidence of slight surface protection by the inhibitors. It has been inferred from this study that both acetone and ethanol are better solvents for extraction of Griffonia simplicifolia based corrosion inhibitors.
