FIELD: transportation.
SUBSTANCE: invention relates to pipeline transport. Substance of invention consists in the fact that repair of steel pipes selected for repeated use is performed. Then each pipe is installed in reinforced concrete well, fixed and centered relative to axis of well. At the tube ends reinforcement units are mounted and at one end of the pipe the impact mechanism is exposed to the number of strokes determined by the pipe durability change schedule depending on the number of strokes causing the voltage value calculated in the pipe by the formula.
EFFECT: invention can be used to increase service life (life time) of pipelines at their overhaul using repaired pipes that were in operation.
