Problems of experimental determination of coefficients of the wear of ship piping systems

The article presents series of considerations relating to experimental evaluation of the reliability of ship piping systems. The aim of this study is to attempt to answer the following questions: What should be the tested element? How to choose the diameter of the tested item? What should be the result of measurements and calculations? How to measure? How to choose the duration of the test? How to choose the sample size and elaborate the results? Can we use a linear relationship between the weight loss of the test piece and the time? At the end of the article, the initial conception of the laboratory stand is proposed.
