(PDF) Efficiency of Green Inhibitors Against Hydrogen

Immersion of API 5L X65 in HCl with 5% green inhibitor is seen to reduce the acid's effect. The improvement of the material's fracture toughness due to the inhibitor was more than 40%. View (PDF) IMPACT RESISTANCE OF API 5L STEEL IN AGGRESSIVE The effect of time and green inhibitor addition in 1 M HCl on API 5L steel X52 and X65 impact resistance is studied. The concentration of green inhibitor of 3, 5 and 10 % is produced by extract of API 5L Pipe Specification (Updated on 2020) - Octal SteelAPI 5L steel line pipe adopts different steel grades, generally are Gr. B, X42, X46, X52, X56, X60, X65, X70, X80. Some manufacturers are capable of manufacturing steel grade up to X100 and X120. As the steel line pipe grades higher, more strictly control on the carbon equivalent control, and higher mechanical strength performances.

Corrosion Behaviour of Bitumen Coated API 5l X65 Steel in

API 5L X65 steel sample used for this research was obtained from SCC (Nigeria) Ltd, Ushafa, Abuja, Nigeria. The reagents used for Corrosion test was HCl with pHs of 2, 3, 4, and 7. The chemical composition of the X65 steel is as shown in Table 1. Table 1:Chemical composition of API 5L X65 low carbon steel. Corrosion Inhibition by a Caesalpinia Sappan L Modified A Caesalpinia Sappan L modified imidazoline has been synthesized and used as a corrosion inhibitor for carbon steel in API 5L X60 in HCl 1M environment.The aim of the investigation is to find low dosage-high efficiency green corrosion inhibitor.The testing techniques include wheel test weight loss measurement, Tafel polarization and Development of environmental friendly corrosion inhibitor Areca flower extract has been investigated as a green corrosion inhibitor on API 5L Grade B in 1 M HCl acidic solution using Linear polarization and Electrochemical Impedance Spectroscopy (EIS). Additions of 4 ml, 8 ml, 12 ml, 16 ml, and 20 ml of corrosion inhibitors increase the efficiency of the inhibitors. Effect of L-Citrulline from Watermelon Seed Extract as a study on watermelon seed extract (WMSE) as a corrosion inhibitor showed an efficiency of 83% at 2 ppm in an HCl solution [7]. Therefore, WMSE as a corrosion inhibitor is compared with the MEG inhibitor under the same conditions. Corrosion inhibition of API 5L X65 steel in a CO 2-saturated 3% NaCl solution by WMSE has been evaluated

Effect of Structural Change on Corrosion Inhibition

investigated for API-5L-X65 steel corrosion in hydrochloric acid by scanning electron microscopy, potentiodynamic polarization and impedance spectroscopy. Aqueous hydrochloric acid was applied to simulate the oil and gas well acidizing fluid. Potentiodynamic polarization studies indicated that compounds retard both the anodic Experimental and Electrochemical Research of an Efficient The results showed that the corrosion rate of carbon steel tube, dirt deposition rate, and limit fouling resistance in the presence of TPP were 0.043 mm·a 1, 12.58 mg·cm 2 ·m 1 and 0.51 × 10 4 m 2 ·K·W 1, respectively, less than the upper limit values of 0.075 mm·a 1, 15 mg·cm 2 ·m 1, and 0.86 × 10 4 m Inhibition of the corrosion of carbon steel in acid Dec 01, 2012 · The impedance diagram obtained with 1.0 M HCl shows only one capacitive loop. The same trend was also noticed for C steel immersed in 1.0 M HCl containing plant extracts, which indicated that the corrosion of steel is mainly controlled by a charge transfer process [21,5]. PENGGUNAAN TIOUREA SEBAGAI INHIBITOR KOROSI corrosion inhibitor of API 5L X65 carbon steel in 1 M NaCl solution at 45oC was 1100 ppm at immersion time of 6 hours (IE = 91.91%) and 500 ppm of thiourea at immersion time of 30 hours (IE = 92.86%).

corrosion inhibitor of API 5L X65 carbon steel in 1 M NaCl solution at 45oC was 1100 ppm at immersion time of 6 hours (IE = 91.91%) and 500 ppm of thiourea at immersion time of 30 hours (IE = 92.86%). Keywords:thiourea, corrosion inhibitor, API 5L X65 carbon steel, sodium chloride, weight-loss method Paper No. 2144Corrosion experiments were conducted on API 5L X65 mild steel specimens covered by a silica deposit in inhibited 1 wt% NaCl aqueous solutions saturated by CO2 at pH 5.0 and 25°C. It was observed that a generic imidazoline based inhibitor was not able to reduce the general corrosion rate of the steel Performance of (HEMIM) (CN) and (DMIM) (Cl) as , of the two ILs on API 5L X52 steel immersed for 120 h in a 0.5 M HCl solution was evaluated in the absence and presence of different ILs concentrations (1 to 100 ppm) at 25 °C. The corrosion rate, v corr, values were calculated from equation (5): = ( 1 2) (5) where W 1 and W 2 Schinopsis lorentzii Extract As a Green Corrosion Nov 22, 2011 · Inhibitive Action of Novel Schiff Base Towards Corrosion of API 5L Carbon Steel in 1 M Hydrochloric Acid Solutions.

THE MECHANISM AND EFFICIENCY OF INHIBITION OF

The electrode material was carbon steel of American Petroleum Institute (API) 5L grade X65 type. The electrode was made by cutting carbon steel API 5L, lathing it to a diameter of 0.8 cm and a length of 2 cm, connecting (soldering) it to a copper wire and coating it with epoxy resin to obtain an area of exposed surface of 1 cm2.
