Abstract

A removable debris shield and method to internally protect a portion of a vessel, such as a pressure vessel, during fabrication. Pliant material sufficient to span a desired interior portion of the vessel has a hem located around the periphery of the material and having at least one opening. A hoop is removably inserted through the opening into the hem to extend the material across the desired interior portion of the vessel. In one embodiment, a spreader bolt spreads the hoop to force it tightly against the walls of the vessel.
