It is suitable for metallurgical and engineering applications where it is required to use an oil film - a thin coating on the inner surface of pipes of different cross section and different lengths, due to: corrosion protection, disinfection, reducing the surface friction of the inner surface, or for other reasons. The formulation of this concept is applicable to a broad portfolio of pipe types of different sizes, cross-sections shapes and lengths. The technical solution falls within engineering and metallurgy fields.
