AB  - Experimental investigation of the integrity of casing pipes, used in the oil drilling rigs, withdrawn after about 70,000 h of service, has been conducted, together with numerical simulation. Pipes were manufactured by the high frequency contact welding (HF) of API J55 steel. The influence of corrosion damage is investigated by means of pressure test of a pipe with different damage levels made by machining the circular holes. The finite element analysis of the damaged pipe subjected to internal pressure is conducted to simulate the stress state in the pipe and to establish the criteria for the maximum pressure that a damaged pipe can withstand. Several analytical expressions were used to estimate the maximum pressure in a damaged pipeline, and the solutions were compared to predictions of finite element models and experimental results.

AB  - Olivine basalt, as a natural material, has excellent physical and mechanical properties such as hardness, compressive strength, wear resistance, color and gloss. On the other hand it is difficult for processing, because of its high values of mechanical properties. Retention of physical and mechanical properties of basalt and its formation is only possible by mixing basalt powder with polymers, which would enable the composite material that can be formed by the casting process into complex shapes. The mechanical properties of the obtained composites and production technologies are, to a great extent, unknown in both, local and foreign literature. Researches conducted and presented in this paper show an overview of tribological behavior of the basaltic composite material, and some technological parameters of the production process. Based on the obtained results, it can be determine the best ratio of components in the composite. These data are important for the development of new composite materials based on basalt, which will have significant application in the future.
