ABSTRACT:
An aqueous tube cleaning apparatus and method includes a cleaning receptacle and a vertical receptacle, which is taller than the cleaning receptacle. A tube, or bundle of tubes, is placed in the cleaning receptacle, extending through an inlet port from the vertical receptacle, and a gate is closed to clamp the tubes in place. The vertical receptacle is then filled with a fluid, and the pressure created by gravity forces the fluid through and around the tubes, cleansing the inner and outer surfaces of the tubes.
