Abstract:

A method of treating pipes to render the inner wall of the pipes resistant to corrosion and pre-mature deterioration. For new pipes, the inner wall is cleansed with a solvent, debris removed, and the inner wall dried. The inner wall is then coated with a corrosion-resistant primer and allowed to dry. The last step is to coat the inner wall with a corrosion- and chemical-resistant topcoat. More than one coat of primer and topcoat may be applied. The pipe may be re-treated by pumping a stripper through the inner wall removing all coating followed by cleansing and re-coating as described above.
