ABSTRACT:
A coating removal machine or carriage (22) for a pipe (10) has an enclosed housing (44, 46, 48, 50) extending about front and rear tool carriers (74, 76) which rotate in opposite directions about the pipe (10) and have coating removal tools (116, 118, 120) for removing the coating material from the pipe (10). The removed coating material (12) is collected in removable bags (66) beneath the machine (22) for disposal at a separate remote disposal site. A dust collector (28) has a vacuum line (32) extending to the enclosed housing (44, 46, 48, 50) to remove minute coating particles which are suspended in air or air borne. One embodiment (FIGS. 10 and 11) is provided for a fixed installation. Another embodiment (FIGS. 13-15) includes water under pressure discharged from nozzles (63B) to remove the coated material (12) from the pipe (10).
