Popis:	Investigations were carried out into the mechanisms, kinetics, and dynamics of the physicomechanical factors determining damage and brittle fracture of pipes of low-alloy steel of the ferritic-pearlitic grade. The results show that due to hydrogen charging at high pressures and temperatures, the subsequent interaction of similar effects, and loading with internal pressure at room temperature the brittle fracture of pipes takes place at stress intensity factor values several times lower than the cracking resistance of the metal in the initial condition and in the period of the effect of external factors. The rate of crack growth, and the form and size of cracks are determined technological heredity. The results were used to improve the accuracy of the methods and the test, conditions of metals and components and also improve the calculation method.
