Essay

In the thesis on the basic of study of physico-mechanical and electrochemical in properties and destruction mechanisms of the long-term operating steel of oil and gas pipelines the existing methods of assessment of degradation metal from the viewpoint of its durability were improved and developed were the new ones. The long-term operation leads to degradation of char-acteristics of plasticity, impact toughness, crack growth resistance and corrosive resistance durability of welded joints.
