A multi-tube inspection system with a reel having a plurality of cameras is placed in the upper header. Each camera is attached to its own lead line and has a light source. An inspector, located in the upper header, aligns each camera with a tube and then operates the reel to simultaneously lower the cameras through their respective tube. As the cameras pass through the tubes, they capture a video image of the interior length of the tube. The video image is stored and relayed to a control center where additional inspectors can review the video image of the interior of the tube. Each video is identified and tied back to the tube in a data base. If a defect is identified, the tube can be taken out of service (blocked off) or scheduled for cleaning. Once cleaned, the tube is then reinspected.
