PIPE, METHOD AND DEVICE FOR IMPROVED PIPELINES AND SIMILAR OBJECTS

摘要

The invention relates to pipes, pipelines and similar objects and can be used for aviation, metallurgy, shipbuilding etc. The aim of said invention is to increase the fault tolerance of a construction. Said invention is characterised in that a pipe is provided with at least one conductive spiral layer for inspecting and repairing the wall thereof by laser. Said layer is formed in the wall by rolling and the filling thereof with glass. Afterwards, said layer is inspected with the aid of optical oscillation, thereby making it possible to detect the wall defect. The distance to said defect is determined by the length of a pipeline and a travel time of pulses. The space of the layer is limited. A crack is repaired by oscillation heat applied towards the opening thereof. Other characteristics including the inventive device characteristics are also disclosed.
