CLEMCO Spin-Blast
The Clemco Spin-Blast is (a highly specialized attachment connected to the end of a pressure blast machine hose) specifically designed to restore any type of pipe to white metal clean without need of rotating pipe. With the complete removal of virtually any contaminant and with a highly desirable “tooth”, the interior pipe surface is superbly prepared for the application of long-life coatings. Applicable for pipe sizes ranging from 8 inch to 36 inch I.D. the unit is a high production favorite of refineries, pipe liners, chemical producers, water and gas companies.
The Spin-Blast can be used with all common abrasives except aluminum oxide and silicon carbide. Simple preventive maintenance allows low-cost operation. Three nozzles of varied orifices and centering (two) carriages are available to accommodate pipes from 8 inch I.D. to 36 inch I.D. Either carriage is quickly adjustable for any diameter within the size range.
The Spin-Blast is connected with 1-1/4 inch pipe lance to a standard Clemco blast machine . Preferably the lance should be the length (up to 40 ft.) of the pipe being cleaned. To operate, the Spin-Blast is first pushed through the length of the pipe while the blast machine is idle. The air is fed from the blast machine which starts the blast head rotating. With full rotating speed quickly obtained, the abrasive control valve on the Clemco blast machine is opened. When the abrasive ejects from the spinning nozzle then the blasting is is progress, signaling the operator to withdraw the tool to clean the entire pipe length. Blasting speed is determined by the specific cleaning requirements. Standard unit delivered with 1/4 inch orifice by 1-3/4 inch long nozzles.
