Carbon Steel Corrosion Control in the Past Twenty Susan P. Rey Carbon Steel Corrosion Control in the Past Twenty Years and in the New Millennium Page 3 of 18 INTRODUCTION Treatments for controlling carbon steel corrosion have changed greatly over the last 20 years and will continue to do so into the new millennium. The reasons for
Carbon dioxide dissolves in brine to form carbonic acid that ionizes to yield a low pH value. The resulting acidic solution strongly enhances the corrosion in carbon steel pipes and facilities. The presence of carbon dioxide would lead to corrosion rates of several mm/year if no proper corrosion protection methods would be undertaken .
Corrosion Allowance - an overview ScienceDirect TopicsEstimating the carbon-steel general corrosion rate using laboratory data and analogue data indicates corrosion rates in the range of 0.110 m/year (3.94 × 10 6 to 3.94 × 10 4 inch/year) in the reducing environment (Yoshikawa et al., 2008; David et al., 2002). Figure 7.2
Corrosion Behavior of Carbon Steel with Pearlite-Ferrite The corrosion behavior of carbon steel under H 2 S and CO 2 environment is firstly studied in the 1940s, and some results have been obtained [5-8]. Masamura et al have investigated a critical ratio of H S CO 22 PP to understand the corrosion mechanism of carbon steel. They have found when 22 PP 200, the corrosion products are FeS and FeCO 3
Corrosion of carbon steel and even alloy steels in micro-environments can be very complex. For example, the pH, moisture content, and chloride level are just three of the variables determining the corrosion rate of galvanized steel in soil.. Corrosion charts are difficult to develop because of the many variables present in any given micro-environment.

Carbon steel, the most widely used engineering material, accounts for approximately 85%, of the annual steel production worldwide. Despite its relatively limited corrosion resistance, carbon steel is used in large tonnages in marine applications, nuclear power and fossil fuel power plants, transportation, chemical processing, petroleum production and refining, pipelines, mining, construction
Frontiers Microbially induced corrosion of carbon steel The metallic low and intermediate level radioactive waste generally consists of carbon steel and stainless steels. The corrosion rate of carbon steel in deep groundwater is typically low, unless the water is very acidic or microbial activity in the environment is high. Therefore, the assessment of microbially induced corrosion of carbon steel in deep bedrock environment has become important
MATERIALS SELECTION5.3.1 Corrosion allowance For carbon steel piping, a corrosion allowance of 3 mm shall be used, unless higher corrosion allowances are required. Recommendation:For submarine pipeline systems a total corrosion allowance of 10 mm is recommended as a general upper limit for use of carbon steel.

Temperature and Corrosion Rate More Complex Than corrosion rate is controlled by a chemical reaction, such as dilute sulfuric acid attacking carbon steel. Even in these situations, the corrosion rate increase with temperature may vary from 1.5 to 2X with each 10°C rise in temperature. But if the corrosion rate is controlled by other factors, such as the presence of oxygen in the corrosive
