ABSTRACT
A significant part of  Vietnamese territory is saturated on soft soil and needs special ground improvement methods in basement construction of the vertical steel tanks. Thus, on the preconstruction stage vertical vacuum consolidation methods are used to increase soil bearing capacity. The consolidation process on the stage of tank filling with the installation of a heat source was examined in this work. The objective of this paper is to form a model for determination the settlement and excess pore pressure in cases of temperature effect or without it. The numerical model results were then compared with numerical solutions of other researches. The results of this work show that the settlement of soil under temperature effect can be determined by Biot’s theory with variation of coefficient of consolidation.
KEYWORDS: thermal consolidation, clay, temperature, saturated soil.

ABSTRACT
The article contains a forecast of technical condition of large diameter pipelines with minor (up to 10% of the wall thickness) stress corrosion defects. In fact, after 30 years of operation, the insulation coating, which lost their protection functions more than 20 years ago, gas pipelines OJSC «Gazprom transgas Ufa» 1420 mm in diameter up to 80% covered by small in depth stress-corrosion defects. The hypothesis is proposed and substantiated that the continued deterioration of the insulation coating and additional oxygen and moisture flow will begin to dominate the general corrosion, which «overlaps» relatively shallow stresscorrosion defects.
KEYWORDS: forecast, stress-corrosion, high pressure gas pipeline.

ABSTRACT
During the transporting, storage and operation of natural gas it is necessary to follow strictly a number of rules because of its high potential of explosion. For minimization of risks of  technogenic accidents, during the operation operating gas inventory and projection of a new one, during the transporting and storage of natural gas, and at its processing, it is necessary to count initially correctly thermal and chemical processes which take place in the composite technological systems. In this regard special importance is gained by a question of a research of conditions of inflaming of the continuous infinite cylinder which is filled with the reactive environment, at heat convection at thermal boundary conditions of the 1st and 3rd sort. In work dependence of the relative temperature on distance to the center of the cylinder, a condition of self-ignition and stability of the received decisions is received, and also approximation of the received expressions is carried out. The received dependences show existence or lack of the critical modes of a current in the hollow cylinder at thermal boundary conditions of the 1st and 3rd sort.
KEYWORDS: self-ignition condition, approximation, stationary heat conduction equation, rational function of Pade, thermal boundary conditions, stability of decisions.

ABSTRACT
The general information on cavitation is provided in article and conditions known at the moment and consequences of its emergence, as hydraulic phenomenon are listed. And also application of these effects in meso is shown and microspaces with new nanoobjects expands the list of possible perspective technologies. Under laboratory conditions were analyzed physics – chemical features low-paraffinic nefty Azerbaijan on borders of a cavitational zone which results are given in the table. Follows that on the basis of cavitational processes it is possible will determine the general consistent patterns of regulation of physical and chemical properties of oil for use in technology of pipeline transport high-paraffinic the crude oils.But, despite improvement of rheological properties of oil if process happens long time, it can lead to emergencies in petrowire systems. The analysis of the mechanism of a collapse of cavitational bubbles showed that a design choice for realization of  the necessary process of a thermal emission – very responsible moment. Besides, also that cavitational excitement of liquid shouldn’t happen near a design wall since the distinguished energy of plasma will start destroying a design wall at once is obvious.

A significant increase in operation parameters of oil and oil products pipelines might be obtained when adding low dosage of polymeric agents for decrease an hydraulic resistance – drag reducing additives (DRA). Based on pilot tests there was offered a calculation method of mean hydraulic efficiency of DRA with a glance to a change in concentration along the pipeline, which is caused by dissolution processes and traffic destruction of active polymers. The method allows predict the necessary amount of DRA for the required flow rate at assumed magnitude of DRA
hydraulic efficiency.

ABSTRACT
Presented in the model increase transfer coefficients for the ascent of the gas bubbles in the liquid and carried out experiments to study this phenomenon offered a more effective way of cooling oil transformers. The influence of gas bubbles on the breakdown voltage of transformer oil. The effect of the flow of oil on the electrical characteristics of the breakdown. It is proposed to use as a cooling gas sulfur hexafluoride, since it is superior compared with the air electrical and thermal properties. The results of the studies transport phenomena in the liquid with gas
bubbles pop industrial systems with controlled diffusion coefficients and thermal conductivity could be developed. The speed of the transport processes of matter and, consequently, the heat transfer rate can be increased by using “bubbling” - the movement of gas bubbles through the liquid. The basic idea is that an increase in heat transfer coefficient of heating oil in the transformer will be carried out at the expense of circulation bubbling sulfur hexafluoride through a space filled with oil.
KEYWORDS: transformer, cooling system, sulfur hexafluoride, heat conductivity, thermolysis, transcillatory heat transfer.
