Sažetak
In the production of welded pipes the fluid for cooling, lubricating and rinsing is applied, which acts as an anticorrosion agent as well. As the production process is finished, pipes are transported to a warehouse. After being stored for a certain period of time, on some pipe areas a corrosion process was observed. The aim of this work was to examine the causes of welded pipes corrosion. Therefore, the chemical composition of the pipe steel, technological parameters of the pipe manufacturing process and the possible pipes contamination during the manufacturing process and storage wereexamined in detail as possible corrosion causes. As in the pipe production process the metalworking emulsion was used, it was assumed that one of the possible causes of the corrosion could be the emulsion. The results of the examination show that the emulsion did not cause corrosion of welded pipes. Key words:steel, welded p
