Hardness of low-carbon steels during shot blasting
Autor: А. М. Cherniavskyi, А. М. Buchynskyi, L. S. Shlapak, М. Ya. Buchynskyi
Publikováno v: Scientific Bulletin of Ivano-Frankivsk National Technical University of Oil and Gas. :26-33
Low-carbon steels are widely used in mechanical engineering. The surface of products made from such steel is often shot blasted for the purpose of cleaning it, hardening the surface layer, forming roughness, etc. Rational technological modes and effi

Investigation of the properties correlation of physical and mechanical characteristics of ferromagnets based on magnetoelastic sensors of mechanical stresses
Autor: L. S. Shlapak, V. V. Tsyhanchuk
Publikováno v: Oil and Gas Power Engineering. :32-39
The determination of the stress condition is a topical issue. At present, various non-destructive examination methods, such as strain gauge, magnetic, ultrasonic methods, and others are used to analyze pipelines stress condition. Each of them has its

Reasons for crack nucleation in welded joints of main gas-pipelines after a long-term operation
Autor: Pavlo Maruschak, Roman Bishchak, L S Shlapak, S. V. Panin
A crack of operational origin in the welded joint of the main gas pipeline is analyzed. The reasons for its nucleation and impact on technological microdefects that were formed earlier during the welding are found. Micromechanisms and stages of nucle
