Design of experimental loop to demonstrate pigging activity

Abstract

Our world is continuously developing by new generation of engineers, artists, politicians, travelers and this list can be continued. They will research, improve and design new reality for the future. One of our missions is to help them by bringing better understanding of existing technologies. This is the goal of my thesis: to create an experimental loop to demonstrate pigging activity in the pipe-lines. This thesis includes two parts: literature study and design process. First part covers the introduction about pig plugs and pigging activity itself. It contains description of different types of plugs, their material, functionality and classification. Requirements for piggable pipelines are also listed in the text. Further information covers explanation of pigging units, launching and receiving stations. Theory about energy considerations for the system also given in the part I. Next topic covered is tracking pig position along the pipeline. To get an understanding about this process, the investiga-tion about GPS principles have been done. Collection information about inner surface of the pipe is next point of the thesis. Extended descrip-tion of different types of corrosion and method of its detection is given in the text. The research about roughness measuring also was performed. Part II of the thesis covers the design process of the experimental loop. This process includes clarifi-cation of objectives, setting requirements, generation alternatives, 3D modeling and listing all re-quired materials for the pipeline components. Moreover, choice of pump and valves also have been done and suggested models was given. In the end of work, suggestion about plug connection with PC and desired interface layout is presented."
