Pipelines and hydraulic systems are widely used in all branches of engineering; their failure can lead to not only economic losses, but also result in serious environmental disasters. To assure the safety of a piping system, it is very important to carry on a routine inspection of pipelines to find out the defects or corrosions and the cause of defects as early as possible. Therefore, this article analyzes the causes of defects in pipelines and hydro-gasified systems in their manufacture, assembly and installation units, as well as in the service. A detailed classification of the fault lines and hydro-gasified systems is reported in this paper. The factors of reliability of a pipeline and communications units are determined. Further improvement of repairing a pipeline system technology is suggested. The research investigated the impact of piping configuration and its material on the system reliability in whole processing. The defects, which can be occurred when connecting pipelines with other elements during their manufacture, installation and in the service, are also presented in this article.
