Removing old or disbonded pipeline coatings, preparing surfaces for recoating, and applying multicomponent liquid coatings can be accomplished over longer stretches of pipe and at reduced cost with over-the-ditch technology that uses water and air or mechanical abrasion. In jobs for United Texas Transmission Co. and Natural Gas Pipeline Co. of America, a proprietary system of high pressure water-jet blasting for cleaning and air abrasive or mechanical-wheel blasting for surface preparation increased productivity and decreased time required for long-line pipe-line rehabilitation. This first of two articles on the process for cleaning, conditioning, and coating pipeline by line-travel equipment details the equipment and procedures and notes tests of the process for asbestos-containing coatings.
