Shot blast cleaning machine of large steel tube outer wall is our company on the basis of introduction of the United States, Italy advanced technology, the use of modern computer simulation technology, developed a model for the outer wall of the steel tube shot blast cleaning equipment, removal of steel surface oxide skin, fully meet the requirements of cleaning the outer wall of the steel pipe coating, meet the large and medium-sized engineering outer wall of steel pipe to clean. It has the following advantages:

（1）The popular small pit structure, saves the cost and time for construction of foundation pit, the solution for water storage pit caused by lifting machine in the pill sand corrosion caking problem.

（2）The large quantity of shot blasting high ejection speed of the fifth generation of centrifugal type shot blasting machine, significantly improves the cleaning efficiency, good cleaning quality, it is a patent product.

（3）The equipment is based on the domestic and foreign advanced technology re design. The shot blasting process to overcome the traditional wire brushes and sand blasting process in dust pollution, cleaning is not thorough, the disadvantage of low efficiency, advanced technology, shot blasting machine cleaning pipe diameter size can according to user needs production.
