FIELD: machine building.
SUBSTANCE: proposed method comprises contactless unearthing, removing damaged coating, pipe surface processing, applying new coating and burying repaired pipeline. Pipeline separate equal-length sections are unearthed while all process job time intervals are equal. Said removing damaged coating, pipe surface processing, and applying new coating are executed without contact between process equipment and pipeline surface and spark-forming mechanical contact of work tools.
EFFECT: repair without interrupting transfer of product, reduced repair interval.
