Abstract

To increase the hydraulic efficiency of pipelines and reduce the rate of intra-pipe corrosion, it is necessary to regularly clean their internal cavity from various contaminants. This especially applies to gathering pipeline systems, heat and gas networks, pollution of which leads to a decrease in gas production volumes and a significant increase in energy costs for transportation. Traditional methods of cleaning such pipeline systems do not always make it possible to increase the hydraulic efficiency of pipelines, besides, they are accompanied by production and technological losses of gas. This can be prevented by using cleaning pigs, however, due to a number of complications for such pipelines, it is necessary to develop and select pigs with increased throughput and study the influence of their material and geometric shape on the efficiency of pipeline cleaning. Therefore, the purpose of the work is to study the dynamics of the movement of cleaning pigs of different geometric shapes made of various hyperelastic materials through horizontal and lowered section of pipelines and their cleaning processes. For such studies, technologies for manufacturing test samples of cleaning pigs of different geometric shapes from various hyperelastic materials have been developed. In order to study the dynamics of the movement of each test sample, determine its throughput and evaluate the effectiveness of its cleaning of pipelines, an experimental installation with glass pipes and elbows was developed and assembled, which contains long horizontal and lowered section. The through-conduit of each test sample of the cleaning pig and the effectiveness of its cleaning of the pipeline were determined experimentally. Based on the results of research, the geometric shape of test samples of cleaning pigs was adjusted to increase their through-conduit. A plan for progressive verification of the pig for cleaning the gahering pipeline systems, heat and gas networks has also been developed, which makes it possible to choose the most effective pig
