“…The working electrode was inserted and operated at a speed of 1000 rpm through connection to a Pine Model MSRX electrode rotator. The rotating electrode with speed of 1000 rpm was prepared for simulating turbulent flow conditions related to data obtained in real life system [24][25][26][27]. The electrochemical cell was connected for LP measurement.…”

In this work, the oligomer of 4-vinylpyridine designated as O(4-VP) was synthesized by hydrogen peroxide initiated chain growth polymerization and characterized in terms of molecular weight and structure by matrix assisted laser desorption ionization time of flight mass spectroscopy (MALDI-TOF MS). The oligomer was tested as corrosion inhibitor of mild steel in brine solution saturated with carbon dioxide, with the main purpose to investigate the effect of inhibitor concentrations and temperatures on the inhibition activity defined in terms of corrosion rate and percent of protection. The inhibition tests were carried out using the methods of weight loss (WL) and linear polarization (LP). Characterization using MALDI-TOF MS revealed that the oligomer has the mass (m/z) in the range 200-2400, which corresponds to chain length of 2-22 repeating units. The results of corrosion rate measurements show that the corrosion rate with the use of oligomer is significantly lower than that without inhibitor, demonstrating that the oligomer functioned as effective corrosion inhibitor, while the 4-vinyl pyridine monomer was found to promote the corrosion. It was also found that the protection by the oligomer increased with increasing temperature and it was predicted the oligomer was chemically adsorbed by the surface of the metal. Keywords: oligomer 4-vinylpyridine; corrosion inhibitor; CO 2 corrosion; MALDI-TOF MS ABSTRAK Dalam penelitian ini, oligomer 4-vinilpiridin, O(4-VP), disintesis menggunakan inisiator hidrogen peroksida untuk pertumbuhan rantai polimer dan dikarakterisasi berat molekul dan struktur molekulnya menggunakan matrix assisted laser desorpsion ionization time of flight mass spectroscopy (MALDI-TOF MS). Oligomer kemudian diuji sebagai inhibitor korosi baja ringan dalam larutan air garam yang jenuh dengan gas karbon dioksida, dengan tujuan utama untuk menyelidiki efek dari konsentrasi inhibitor dan suhu pada aktivitas inhibisi yang dinyatakan dalam bentuk laju korosi dan persen proteksi. Tes inhibisi dilakukan dengan menggunakan metode kehilangan berat (WL), dan polarisasi linier (LP). Karakterisasi menggunakan MALDI-TOF MS

“…Most studies have dealt with different corrosion environments, such as freshwater, seawater, and NaCl for API 5L series. For pH value under turbulent flow conditions, the results showed that the corrosion mechanism was mainly controlled by mass transport at pH=4 (Rustandi et al 2013). In addition, different pH values and concentrations of various exposed solutions affect the corrosion behavior of heat-treated samples (Sharma and Chhibber 2019).…”

Steel pipelines are commonly used in the petroleum industry where high strength and durability values are required. In oil installations, the problems of corrosion, especially with crude oil, appear clearly and dramatically, in dealing with API 5L series. Improving the corrosion protection and mechanical properties are a genius goal for steel manufacturers, the heat treatment processes are familiar with this field. In this study, experimental investigations were executed to find the heat treatment influence on the corrosion rate, microstructure, and mechanical properties behavior of API 5L X60 pipeline steel in the presence of three different environments: seawater, freshwater, and crude oil. Two austenitizing temperatures 900°C and 800°C were prepared followed by quenching at 600°C, 450°C, and 300°C respectively, where the corrosion rate was estimated by the mean weight loss method. In this study, more than 60% of the corrosion rate in both seawater and freshwater was improved at 900 ºC austenitizing tempered at 300ºC for the selected pipeline specimens while only 22% reduction was achieved in crude oil. Different microstructure phases appeared in the heat-treated specimens such as tempered martensitic at 300°C and fine-grained ferrite with polygonal ferrite at 600°C. The microhardness values decreased with increasing the tempering temperatures while impact toughness values increased with tempering temperature increasing from 300°C until it was reached 450°C and then return to decrease again in 600°C.
