Abstract: The subject under consideration is manufacturing of a test stand, which allows to determine the operational properties of concrete coated pipes necessary for calculations made when designing sections of main pipelines. In particular, the test stand makes it possible to determine the elastic-strength parameters of a concrete coated pipe, such as flexural rigidity, which is especially important for calculating stresses in the area of girth welds that are not concrete coated.
The design under consideration has been developed in the process of research activities carried out by Gazprom VNIIGAZ since 2010 on test sites organized by domestic manufacturers of concrete coated pipes. An overview of earlier designs of test stands is presented.
The test stands are intended for examination of pipe bends. The overview provides a description of their features and disadvantages. The design features and original technical solutions used in the design of the test stand which made it possible to significantly reduce the costs of its production are described. A brief exposition of the methodological basis for processing the experimental data is given.
The development of the test stand allowed to expand understanding of the mechanism of interaction of elements of the pipe concrete system and to obtain valuable data on the elastic properties of the concrete coated pipes that cannot be obtained by calculation with sufficient reliability. Based on the results obtained, it is planned to expand the research tool set that allows to determine the influence of the structural features of the concrete coating on its operational properties during the tests of new types of pipe products with the purpose of further improving the standards that establish requirements for the concrete coated pipes.

Keywords: pipeline ballasting, concrete coated pipes, underwater crossing, offshore pipeline, bending test, pipe testing equipment.
