The effect of welding and heat treatment modes on mechanical properties and corrosion resistance of welded joints of oil line pipes is studied. It is shown that high-frequency welding followed by high-temperature annealing provides strength and corrosion properties in welds of pipes from low-carbon low-alloy steels at the level of the welded metal. © 2013 Springer Science+Business Media New York.

The effect of inoculation, microalloying and heat treatment on the mechanical properties and on the resistance of steel 15Kh5M to carbon-dioxide corrosion and stress corrosion cracking is determined. Comparative analysis of the morphology and composition of products of carbon-dioxide corrosion formed on steel 15Kh5MFBCh under laboratory and field conditions is performed. © 2013 Springer Science+Business Media New York.

Comparative analysis of processes of corrosion-mechanical fracture of carbon and alloy steels in environments containing hydrogen sulfide is performed after laboratory (NACE TM0177) and field tests. The mechanism and kinetics of the evolution of fracture in steels of the two groups are considered. © 2013 Springer Science+Business Media New York. Source

Corrosion fracture of tubing from steels 35G2S and 30KhMA in CO 2-containing media is studied in laboratory and field tests. The laboratory tests are performed at 60 C for 120 h in an air-tight thermostatically controlled vessel with an environment saturated with CO 2; the field tests are performed for test pieces cut from tubing produced from steels 35G2S and 30KhMA after 120 days of operation. The structure and the composition of the corrosion layer are determined. © 2013 Springer Science+Business Media New York. Source

The effect of chemical composition and structure of the metal of oil line tubes on the evolution of corrosion damage is studied for aggressive conditions of oil gathering. The corrosion resistance of the tubes is shown to depend on their chemical composition and structure of corrosion products on the surface. © 2013 Springer Science+Business Media New York. Source
