FIELD: oil and gas production.
SUBSTANCE: invention is related to oil industry and may find application for protection of existing pipeline of watery oil collection and preparation against corrosion. Device comprises protectors and units for connection with pipeline, besides, protectors are serially fixed on bearing rod by means of welding, reinforcing cores of protectors are connected serially to each other by means of welding, protector length, transverse size of protector and diametre of protector with rod and pipeline diametre are selected as providing for protector passage with rod inside pipeline with pipeline bend angle of more than 150°, assembled device is installed in pipeline on section with angle of pipeline bent of more than 150°, and as units of connection with pipeline, the first and last reinforcing cores are connected to pipeline body by means of welding.
EFFECT: the device allows to protect long pipeline from corrosion.
