Abstract

To thoroughly clean, both the inside and outside of pipe and tubing, and both the threaded end and the coupling end of pipe and tubing, for a distance of 18 to 24 inches from end of pipe, a cleaner assembly includes at least one rotating brush that revolves around the outside of the pipe and at least one brush that rotates inside of the pipe. Preferaby one internal brush is provided for the threaded end and two brushes are provided for the coupling end. The second internal brush is larger and cleans the coupling threads as the pipe is moved into and from the cleaner. Cleaning fluid is introduced to the brushing areas, and is reclaimed during the cleaning operation. The cleaner is attached to a raising and lowering device that also accepts a removable spray cover and a pipe seal. The raising and lowering unit is mounted on a stand that contains the fluid collection, fluid cleaning and fluid storage system.
