FIELD: construction.
SUBSTANCE: method comprises cleaning the outer side of the pipe, applying the polymeric insulating material on the outer side of the pipe, and setting the tips in the end sections of the pipe. The tips are made of a corrosion-resisting material, and the inner surface of the tips is conical. The smaller base of the tip faces the pipe end. The coating is applied uniformly and thickened by the forced vibration of the cementing head with the use of vibrator.
EFFECT: improved quality of coating.
