FIELD: chemical industry; oil-producing industry; natural gas industry; other industries; devices for deposition of the protective coatings on the internal surface of the pipelines.
SUBSTANCE: the invention is pertaining to the devices for deposition of the protective coatings on the internal surface of the pipelines. The installation includes the body with the fixed in it driving gear. For the purpose to increase the volume of the coating material it is placed in front of the installation between the locking and batching disks. At the installation motion the batching disk ensures the coating material feeding through the holes disposed along the circumference of the disk. Preliminary deposition of the coating is exercised by means of the radial vanes, which press it to the internal surface of the pipeline and have the screw-type shape for kick- forth of the surplus of the coating material in the driving direction. The final formation of the surface layer is implemented with the help of the smoothing vanes installed with the capability of regulation of the force of the pressing-down to the coating and ensuring the uniformity even at the shift of axes of the pipeline and the installation. The technical result of the invention consists that the volume of the used coating material is increased at simplification of the installation design, feeding of the solution and the installation operation and maintenance, at obtaining the qualitative uniformly applied coating.
EFFECT: the invention ensures the increased volume of the used coating material, simplification of the installation design, the process of feeding of the solution, operation and maintenance of the installation, at production of the qualitative uniformly applied coating.
