Annotation: Stochastic-statistical method of rating safety coefficient according to pipe material is offered for analysis of main pipeline strength and stability. Relation between safety coefficient corresponding to pipe material and the index of breaking stress variation is stated, and this allows to substantiate the admissible defectiveness level of pipes for main pipelines.

 

Key words: strength, load, safety, defect, pipe, pipeline, rating.
