Blasting apparatus for removing existing coating product or corrosion product the inside of a pipe

摘要

The present invention relates to a device for blasting to remove existing coatings corrosion products of the tube and pipe An apparatus for removing the old coating to corrosion products from the inner surface, and a moving object moving along the inside of the pipe, pivotally mounted to a moving object, hitting the inside surface of the tube by the centrifugal force due to rotation to the existing coating by and a rotation member for removing corrosion products hit, generates a driving force for rotating the rotary blow member, and a drive unit mounted on the moving object. Accordingly, the present invention is cut off for a long period of time by removing a tube of corrosion progress correctly by hitting existing coating and brushing of the corrosion products such as rust and scale, as the water to create a centrifugal force that is attached to the inner surface of the pipe and, in a subsequent process by increasing the adhesion of the material to be coated to prevent corrosion on the inner surface tube sikimyeo maximize corrosion protection of pipe, the pipe produced by the conventional coating corrosion products adhered to the inner surface of the pipe from the quick to be removed has the effect of reducing the time and cost of the process to prevent corrosion.
