Abstract
Commonly known, diagnostic results show that all pipelines contain a large number of defects that are unacceptable in terms of standards and building codes. An attempt to eliminate all defects can lead to the fact that the costs of further operation will become prohibitively large and not economically justified. In practice, the only way to ensure safety is to exclude only those defects that really pose a danger to the pipeline, taking into account the operating conditions. This is how the problem of assessing the residual resource of objects that have been in operation for a long time appears.Authors do not always use the same meaning in the term “residual resource”. To avoid confusion in terms, the article provides some considerations defining this term and accepts an interpretation in which it is a value derived from the strength and safety of the pipeline. A number of factors are given, which in a key way affect the strength and safety, which should be involved in the assessment of the residual resource. As a result, this approach, in contrast to the previously available ones, allows taking into account all the main factors affecting the strength, durability and safety of the pipeline.
