We analyze the causes of the in-service loss of integrity of drill pipes made of G105 steel connected with their premature stress-corrosion fractures. In this case, the mechanical characteristics of steel are satisfactory, except a somewhat lowered e

We propose a microfractographic method for the evaluation of the technical state of rolled carbon steels after long-term operation based on the construction of a correlation dependence between the brittle fracture resistance and, in particular, impac

We investigate 12Kh1MF steel of two bends of the main steam pipelines of thermal power plants. It is shown that they are damaged by the mechanism of intergranular fracture due to creep. In one of these bends, despite the agreement of the metal in all

We compare the mechanical and corrosions characteristics of 17G1S steel in the intact state and after its operation for 40 yr in a gas main. The low sensitivity of the strength characteristics of steel and its modulus of elasticity and much higher se
