Chemical, Hydrodynamic, and Metallurgical Factors in West Siberian Oil Pipeline Corrosion Failure

Investigation on Boronizing of N80 Tube Steel

“…A relatively inexpensive material widely used for tube in oilfield is N80 steel, but according to the investigation on degradation of the tubing metal in hydrogen-sulfide environments by Radkevych and Zavyalov, 7,8) it displayed unsatisfied performance under severe conditions of high corrosion and heavy wear environments, especially in acid environment containing CO 2 and H 2 S. To improve the wear and corrosion properties of tube, various surface techniques have been employed including nitriding, electroless Ni-P coatings and hard Cr coatings. Martini et al 9) reported the wear behavior of the boride coating thermochemically grown on an iron and a medium carbon steel by pack boronizing, in comparison with other surface modifications, such as nitriding, hard chromium coatings and In present paper, boronizing was applied to N80 steel tube by pack boronizing, and its effect on mechanical properties, wear and corrosion of N80 tube steel was investigated.…”

Tribological properties of glass fibre-reinforced Nylon 66 and quenched ductile iron against Al2O3 counterpart under oilfield water lubrication

“…The relatively cheap metallic materials for tube in oilfield, such as J55, N80, and P110 steels, display unsatisfactory performance under combination of high corrosion and heavy wear in environments containing CO 2 , H 2 S, and/or partial wear between tube and sucker rod in the deviated oil well [1,2]. The newly developed Al 2 O 3 ceramic-lined composite steel tube of about 10 m length by centrifugal self-propagating high-temperature synthesis (SHS) process, as a promising alternative to the structural steel tube and conventionally coated tube by nitriding, electroless Ni-P coatings and hard Cr coatings, exhibits substantial advantages in terms of hardness, wear resistance, and anticorrosion [3,4].…”

Comparative Studies on Friction and Wear Performance between Glass-fiber Reinforced Polyamide 66 Composite and Ductile Irons on Ceramic Al2O3 Counterface in Sucker Rod Centralizer Application

“…For a long time, enormous efforts have been made to understand the corrosion behavior and estimate the workability of various tube steels in acid environment containing CO 2 , H 2 S. 1,2) Most of metallic tube materials such as J55, N80 and P110 steels, which are relatively cheap materials and have been widely used for tube in oilfield through the world, display unsatisfactory performance under conditions of high corrosion and heavy wear in the oil well. 3,4) Engineering ceramics is known worldwide because of its high operating temperature, corrosion resistance and wear resistance. Odawara successfully developed long ceramic-lined pipes using centrifugal self-propagating high-temperature synthesis (SHS) process, 5) which were used in many industrial applications to transport solid powder such as coal powder, cinder, coal ash, limestone flour, and also the ideal tubular product for other solid particles and waste slag transportation in the coal, metallurgy, mine, nuclear power industry.…”
