dc.description.abstract	Steel is the most important alloy used in oil and gas industry from production and processing to the distribution of refined products. In this research is analyzed the production technology of steel intended for long pipeline used in conveying gas and oil in the natural gas and oil industries. Data from 14 melts were analyzed. The basic oxygen furnace (BOF) is used for steelmaking. The secondary refining processes were conducted at the ladle furnace station by forming an active ladle slag and using the mixing of bath with argon. Steel degassing is conducted in RH vacuum degassing equipment. The variation of chemical composition, especially the content of carbon, oxygen, and hydrogen, was analyzed according to parameters of industrial technology.	ro_RO
