Abstract
A surface treatment device is disclosed which is capable of effecting surface treatment of the inside and outside of large diameter pipe sections. The device preferably employs an airless centrifugal blast wheel mounted on a support arm which is extensible into and out of the interior of the pipe section or, alternatively, along the exterior of the pipe section. The support arm contains the necessary power cables and ducts to connect the blast head to a dust collector and control panel. The pipe section is rotated on a motorized roller bed.
