The corrosion inhibition of API 5L X60 pipeline steel in oil well acidizing fluid stimulated with 1.0 M HCl by Tranexamic Acid (TXA) was investigated using potentiodynamic polarization (PDP), electrochemical impedance spectroscopy (EIS) and the conventional gravimetric or weight loss (WL) techniques at temperatures ranging from 303 to 323 K. Surface morphological analysis was carried out us...

In this work, the hydrogen fatigue of pipeline steel X60, its girth welds and weld defects were investigated through in situ testing. A novel gaseous charging set-up was developed, which involves a sample geometry that mimics small-scale with high internal gas pressure. The effect by measuring crack initiation growth, using direct current potential drop (DCPD) set-up, probes outer surface speci...

The need for predicting pipeline service life and improving risk assessment relating to corrosion hazards requires establishing a correlation between the rate (CR) of steel its coating condition, cathodic protection (CP) levels surrounding soil conditions. This paper presents systematic study CR bare coated—with without dent or holiday defect—X60 in simulated field environments. Three CP scenar...

The most economical way to move liquids and gaseous hydrocarbons is by using pipelines. According several international organizations oil companies, the use of fossil fuels will continue in following decades. For this reason, it important studying different corrosion mechanisms their origins. One that provoke small leaks, affecting pipeline hermeticity, pitting corrosion. It well-known non-meta...

This work discusses the design and demonstration of an in-situ test setup for testing pipeline steels in a high pressure gaseous hydrogen (H2) environment. A miniature hollow pipe-like tensile specimen was designed that acts as gas containment volume during test. Specific areas can be forced to fracture by selective notching, performed on weldment. The H2 used minimised so safely without need s...

A large amount of oil and gas production needs to be followed by optimal pipeline maintenance. Most cases pipe leaks are sudden in nature that able cause losses over a long period time. The consisting sand particles increase erosion rate, especially at the elbows. Cases prevented through routine inspections based on accurate rate predictions. This study aims predict elbow piping systems using c...

The inhibition performance of a novel benzenesulfonamide-based benzoxazine compound in the corrosion X60 carbon steel an acidizing environment has been examined including some highly electronegative atoms.
