摘要

"high pressure shot blasting device to burnish the internal surfaces of steel tubes. shot blasting method for internal steel tube surfaces and method to produce steel tubes with high quality textures on internal surfaces": offers a shot blasting device to be used on internal surfaces of steel tubes that have a better blasting performance as well as the ability to sufficiently blast the internal surface of a steel tube from its front to its rear: a blasting method .tenting to be used on the inner surfaces of steel tubes, together with a method for producing internal surfaces on steel tubes with excellent textures.The blasting device for blasting the inner surfaces of steel tubes includes a tubular unit (21 ) inlet fluid conveyor, connected to one end of a horizontal steel tube (6) and a negative pressure suction unit connected to another end of the steel tube 6, which is characterized by the fact that the abrasive material or the polishing material 5 is injected horizontally into the inlet fluid carrier unit together with the inlet fluid from the orifice 19 formed at the edge of the unit tube for transporting the inlet fluid 21.
