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.
Claims14
A method for treating a tubular comprising:
- passing an ablating mass of gelatin through said tubular wherein said mass contacts the interior wall of said tubular and ablates to deposit a layer of gelatin and magnetic particles on said wall;
- said mass comprising;
- a mixture of (a) common gelatin of the type derived from collagen and used in foods, glues, and the like, (b) a heated liquid, and (c) magnetic particles wherein said mixture is then cooled to allow said gelatin mixture to gel and form said ablating mass of gelatin.
