Автор: Oleg Tarayevs'kyy

The results of experimental studies and analyzed the impact of long-term operation of gas pipelines, as well as natural stress concentrators on the physico-mechanical properties of welded joints of steel 17G1S. The technique and the regularities of the destruction of the material of welded joints of gas pipelines under static and low frequency loading for long term use, as well as stress concentrators. Some aspects of the mechanism of fracture of welded zednantruboprovodiv who are in long-term operation, as well as stress concentrations.
Key words: fatigue, floods, stress concentrators, weld of unity, weld, gas, static load, low-frequency loads.
