Each control coupon must be weighed before and after cleaning. . Approach to vertical tanks' industrial painting: To reduce the danger of corrosion damage to the metal frameworks, that can bring the tank out of operation, it is essential to provide a certain system of rust and corrosion protection measures, that includes applying protective coat and (or) increasing the thickness of the metal plates (corrosion allowance), which is meant to consider . The means and methods of creating a surface that is in a condition to accept the type of coating specified.
