EXPERIMENTAL STUDY OF STRESS-STRAIN STATE PIPELINES WITH DEFECTS TYPE DENT
In this work, experimental research pipeline with defects such as dented. On pipes of different diameters were initiated by dents, identified by their geometric characteristics. The measurements of hardness and microstructure of the metal within the defect formation. The regularities of changes in the strength characteristics of the metal samples cut from the body tube, when a tensile test. Based on experimental data the experimental dependence and draw appropriate conclusions.
KEYWORDS: pipeline, defect, dent, stress-strain state of the experiment, samples, hardness, microstructure, tensile strength characteristics, experimental dependence.

DEFINITION OF QUALITY OF A CONCRETE LAYER OF THE BALLASTED PIPE
This work is devoted to the problems concerning area of technical diagnostics of a linear part of the main pipelines. It is a question of the entrance control обетонированной a pipe applied construction of sites of the main pipelines in обводненных conditions and at a construction of transitions, through water obstacles. The existing practice of such control does not mean quality check of a making heavier layer.
KEYWORDS: main gas main, pipe covered by concrete, ultrasonic control, strength of concrete, quality of concrete.

INNOVATIVE TECHNOLOGIES FOR THE TYPE AND ARRANGEMENT OF CARGO TANKS OF LNG CARRIERS
As of today reliability requirements as well as industrial and ecological safety requirements are imposed on the cargo tanks of LNG carriers. Two new technical decisions were made: input cylindrical cargo tank and membrane cargo tank. The construction-costing and the technical and economic analysis were carried for input cylindrical cargo tank.
KEYWORDS: LNG carriers, liquid natural gas, cargo containment system, Finite element analysis, calculation of costs of new building.

B.N. Mastobaev
In this article for the comparative analysis four LNG plants were chosen from four Middle East countries (UAE, Oman, Qatar and Iran) with be biggest proven gas reserves. All these LNG plants are located or will be located in the comparatively similar geographical, climate and even economical and political conditions. Technological processes of all of these plants include gas treatment stage. Description of the gas conditioning process on each of these plants is given. Gas treatment stage is important on these plants and for any other plant as all the undesirable elements should be removed before the gas liquefaction. Some of the problems solutions in gas treatment are also described and analyzed.
KEYWORDS: liquefied natural gas, LNG, Middle East, gas purification, separation of acid gases, the preparation of the gas to liquid, gas composition, the specification of the gas properties of the gas.
