METHOD OF AND DEVICE FOR APPLYING CORROSION-RESISTING COATING ON INTERNAL SURFACE OF PIPELINE Russian patent published in 2002 - IPC

Abstract RU 2179076 C2

FIELD: agriculture and reclamation facilities, particularly, methods of applying fluid material on the internal surface of hollow body (pipe). SUBSTANCE: coating is applied on the internal surface of pipe-line at a speed of 0.3-0.5 m/s. The device is provided with means of the individual supplying of coating material and rust transformer under operation pressure. The means are connected with the injection nozzle. The nozzle is conical and receives threaded rod provided with turns of screw. EFFECT: enhanced efficiency due to reduced consumption of paint coating. 2 cl, 4 dwg
