Abstract

Background. Pipeline strengthening technique by applying well-bond joints filled with molten metal or an alloy has been examined. The main disadvantage of the above mentioned technique is that it is difficult to ensure under-joint area sealing.

Objective. To develop the strength increasing technique of the high pressure pipelines parts using the well-bond joints filled with molten metal enabling to achieve high efficiency of medium and small diameters tubes strengthening.

Methods. Strength increasing technique of a working pipeline with the help of well-bond joints.

Results. Improved active pipeline's defective areas maintenance technique has been offered. We have also offered face seal design that makes it easier to form under-joint layer that has optimal parameters.

Conclusions. The offered technique improves the efficiency of strengthening the average and small pipes diameter.
