South Caucasus with its geopolitical position and diversity of natural resources is a unique region in the world. A concrete expression of this fact is the EU’s “TRACECA” project, which binds the Central Asia, Caspian and Black Sea basin states to one another. This line the Eurasian freight logistics corridor runs through the South Caucasus, which guarantees the economic growth and stability in countries of the region. Strengthening the transit capacity of the South Caucasus countries and improving overall competitiveness of transport corridor will be contributed by the development and formation of a new concept of a single transport and logistics system – the regional customs logistics.

In order to allow fast, safe and efficient movement of commodity flows through the South Caucasus transport corridor, the regional customs logistics should create a single standard of customs processing of freight. This can be accomplished within the “ASYCUDA World” program by creating the appropriate module.

In view of the new realities created by signing the Association Agreement between Georgia and the European Union, Georgia for the first time was given the opportunity to be properly involved in the processes of global economic integration. This problem can be successfully resolved through safeguarding the Euro-Asian transport-communication space – “A New Silk Road”, and in the conditions of harmonizing the country’s geo-economic interests.

It should be noted that the first test train has passed already through the Georgian section of a new Baku-Tbilisi-Kars railway line.
This section is what should become a component part of “A New Silk Road”. The construction of 180 kilometers of this railway line has been already completed, and now everything is being done for completing all works by the end of 2015. This railway line is considered as the most significant project in the South Caucasus region of the Euro-Asian transport corridor.

The crude oil samples produced from various fields are characterized by wide range of rheological characteristics. On the quantitative indicators of these parameters and, consequently, on the hydraulic resistance of the oil flow movement through the pipeline, significantly depend the possibilities of increasing the pipeline transport carrying capacity.

The created physical model enables to determine rheological parameters of crude oil of various types, such as dynamic viscosity and solidification temperature with the dependence on preheating temperature and concentration of specialty solvents.

Transportation of oil and oil products through the pipeline, due to their high viscosity and the paraffin content is technically and technologically complex process. At present, for the purpose of improving rheological parameters of oil, one of the most effective methods consists in its heating in heat-exchange installations to a certain temperature. The degree of improvement of rheological parameters of oil depends on its heating temperature and conditions of subsequent cooling. Heat treatment improves the inlet capabilities of pumps and allows improving the oil transportation process through the main pipes and pipelines.

The given paper dwells on the design procedure of the heat-exchange installation “the pipe in pipe”. Such type of heat-exchanger is characterized by a simple design and low hydraulic resistance, in which the hot heat transmitter is ecologically clean water.
The process of oil heating in heat-exchanger is the process of convective heat exchange, the intensity of which depends on a number of parameters, including the oil density and viscosity, which in turn are the values depending on temperature. On that basis, the paper dwells on the design procedure of the heat-exchange installation (“the pipe in pipe”) that should enable us to ensure the optimal heating temperature and calculation of geometrical sizes of heat-exchanger through mathematical way.
