This technical book is written for pipeline practitioners. Numerous examples from daily work practice assist engineers and technicians in solving their operational tasks. Everyday pipeline issues, from pressure loss to cavitation in pumps, orifices, or control valves, are described in detail, avoiding lengthy academic discussions. Beyond presenting examples, concrete solutions are provided, with particular emphasis on relevant influencing factors that should be considered. The exemplary nature of the book illustrates that practical knowledge transfer based on specific problems from work practice is more effective than many pages of purely theoretical explanations. The pipeline manual is primarily based on the author's professional experiences as well as insights gained.
