Effect of Initial Films of Copper on Moundless Type Pitting Corrosion of Copper Tubes

Masahiro Sakai, Osami Seri

pp. 434-440

DOI:

10.3323/jcorr.58.434

Abstract

Copper tubes were immersed for one year in fifteen kinds of synthetic freshwater to reproduce a moundless type pitting corrosion. Most or part of the area of some specimen surfaces changed its color into dark brown for about one week immersion. Such a dark brown area formed in freshwater for about one week immersion is called “initial film” of a copper. The formation of the initial film was accelerated in the test water containing a chloride ion. After one-year immersion tests, moundless type pitting corrosion occurred on the specimen immersed in the test water containing 40 mg SiO₂/L, 50 mg SO₄²⁻/L, 10 mg Cl⁻/L and 10 mg HCO₃⁻/L. These pits were located on the boundary of the initial film. The initial film was formed intentionally by one-week immersion in the solution containing silica and chloride ion. Cathodic reductions of the initial film revealed that the thickness of the initial film was about 400 nm of cuprous oxide. The galvanic corrosion test was performed using galvanic couples of a copper tube with the initial film and an as-received copper tube. The galvanic current flew from the copper tube with initial film to the as-received copper tube. This result indicates that the macro-cell formation of the area with an initial film and the area without an initial film causes the moundless type pits on the boundary of the initial film.

Development of a New Design for Corrosion Prevention in NH₄HS Environments

Kazuhiro Toba, Koji Kawano, Jun'ichi Sakai

pp. 441-447

DOI:

10.3323/jcorr.58.441

Abstract

NH₄HS corrosion has been a serious problem in oil refining plants. The corrosion rate dramatically increases over a certain concentration of NH₄HS. In high pressure plants such as hydrodesulfurization units which are operating in NH₄HS environments, leakage caused by corrosion could result in catastrophic disaster. Therefore, in the design phase, corrosion prevention techniques should be considered. In this study, a new design philosophy to prevent NH₄HS corrosion in a sour water environment was successfully developed based on simulation techniques.
