FIELD: technological processes, coating.
SUBSTANCE: invention concerns pipe coating, particularly system and method of coating and/or renovation of worn or pitted pipes in order to extend lifetime and improve performance. Internal pipe device includes conical coating element featuring several distanced edges. End flange can remove excessive coating material from pipe. This system and method allows application of thin coating film onto internal pipe surface with regular thickness covering all pipe areas. Coating material can be selected to minimise heat conductivity change or to ensure such work fluid medium change inside the pipe as to prevent negative interaction of the medium with pipe material.
EFFECT: regular coating of internal pipe surface.
