Key words: diffusion zinc coating, tubes, corrosion resistance, oil and gas production.

Basic properties of various zinc coatings were compared, and particular attention was paid to diffusion zinc coatings of a new generation Delta 5+ designed for the protection of tubing during oil production. Results obtained in field tests of zinc coated tubing in deep oil wells are presented.
