摘要：
A new approach to the repair of main pipelines by welding without removing them from service is proposed. The approach is based on four points: ranking of defects by the degree of failure risk; safety of welding works on pipeline under pressure; use of different variants of repair by welding; serviceability evaluation of welded repair constructions. The use of this approach makes it possible to minimize pipeline failure risk and to predict pipeline serviceability after repair by welding.
