Comprehensive studies and in-field tests established that one of promising ways of protection of tubes and equipment for oil and gas production is application of thermochemical diffusion zinc coating. High field-performance data of diffusion zinc coated tubing and their threaded joins and prospects of their use in difficult conditions of oil and gas production were demonstrated. A new standard for diffusion zinc coatings is developed by International Standard Organization with participation of Ukraine and Russia. It is expected to be in force in 2015.
