ABSTRACT:
A method and apparatus for treating tubulars (e.g. pipelines, flowlines, tubing, casing, etc.) for corrosion, drag reduction, or the like wherein a mass comprised of a gelatin mixture and magnetic particles is passed through the tubular to deposit a protective layer onto the inner wall of the tubular. The micro particles of magnetized material are entrained within the mass of gelatin and are deposited along with the gelatin to aid in adhering the protective layer on the tubular wall.
