The paper considers the main criteria for selecting polymer pipelines for water supply and sanitation systems that will ensure compliance with the requirements for reliability and safety throughout the life cycle. Calculation of the limiting conditions of the pipeline, taking into account the maximum number of significant factors, is one of the conditions for ensuring these requirements and allows choosing a pipe with optimal parameters in the framework of the task. At present, no method recommended for calculation fully takes into account the factors affecting the onset of the pipeline extreme conditions, moreover, each of these methods takes into account its own set of parameters, which does not allow a reasonable comparison of the results obtained.
