“…The development of research techniques also enables more effective research. The available literature presents many results of research on the corrosion of low carbon steel [25][26][27][28][29][30][31][32][33]. The problem is the ability to compare research results with each other.…”

Steels dedicated to work in a corrosive environment are corrosion-resistant steels. Nevertheless, unalloyed steels also work in corrosive environments. Low-carbon non-alloy steels are a popular construction material for pipelines. They owe their popularity to low costs and good susceptibility to welding. An example of the use of steel is pipelines for the transmission of various substances. These substances often contain sodium chlorides. Unalloyed steels are prone to surface corrosion. This type of corrosion does not pose a high risk of failure, is completely predictable and can be monitored very well by measuring the wall thickness of the pipeline with non-destructive methods. Pipelines can be placed in production halls. Unless the temperature of the flowing medium is increased (these steels are not usually used for work at reduced temperatures), their operating temperature is about 20-25oC. Taking the above into account, tests of the corrosion rate of the popular P235TR2 steel grade at 25oC were carried out. The corrosive environment was a 10% NaCl aqueous solution. Samples were taken from the tube and soaked in NaCl solution for up to 432 hours, with weight loss determined every 48 hours. It was found that P235TR2 steel has a satisfactory corrosion resistance to low concentrations of NaCl at 25oC. The nature of the corrosion process was classic and consisted of two typical stages. In the first, the steel showed high resistance to the applied corrosive environment, in the second, due to the progressive development of the surface, the corrosion rate increased at a higher rate.

“…The course of the corrosion process is determined, among others, by: the type of material, type of corrosive medium, parameters of the flowing medium [12][13][14][15][16][17][18][19][20][21][22][23]. A common corrosive medium is a NaCl solution [24][25][26][27][28]. The most common type of corrosion of carbon steels is uniform corrosion.…”

Metal alloys working in real conditions are exposed to aggressive environments. The degree of aggressiveness of the environment may vary. Therefore, various construction materials are used to build machines and devices. One of the groups of materials widely used in industry are low-carbon steels. They owe their popularity mainly to the low price and relatively good technological and functional properties. These steels usually work in a low-aggressive environment. Pipelines are a typical application for low carbon steels. Pipelines are protected from corrosion on the outside, while the inside (working side) is not protected. One of the media in the pipelines is a liquid with a low concentration of NaCl. Pipelines are usually located underground, so their operating temperature is almost constant in the annual cycle and amounts to approx. 10 °C. Taking the above into account, tests were carried out on one of the most frequently used steel grades, P235TR2, for the construction of pipelines. The tests were carried out at a temperature of 10 °C in a 10% NaCl aqueous solution. After preparation, the samples were soaked in a corrosive solution for up to 432 hours. Corrosion loss was determined by the gravimetric method. Relative corrosion and corrosion rate of steel in the tested medium were calculated. On the basis of the tests carried out, it was found that P235TR2 steel has good corrosion resistance in the environment of 10% NaCl at 10 °C. The corrosion was divided into two stages. In the first, a slow progress of the corrosion process was noted, in the second, a gradual increase in the corrosion rate was noted. The increase in the corrosion rate is the result of the surface development that occurs as a result of corrosion. With the possibility of contact of the corrosive medium with a larger surface, even with the constant impact of the corrosive agent, there is a greater corrosion loss, which translates into an increase in the rate of corrosion.
