BLASTING METHOD FOR REMOVING EXISTING COATING PRODUCT OR CORROSION PRODUCT THE INSIDE OF A PIPE

摘要

The present invention relates to a method for blasting to remove existing coatings corrosion products of the tube and pipe As a method of removing the existing coating to corrosion products from the inner side, while moving along the inside of the blow tube to strike the inner surface of the tube by the centrifugal force due to rotation of the coating to remove the existing corrosion products from the inner surface of the pipe phase with, the existing coating to corrosion products separated by hitting the inner surface of the tube comprises a brushing step to remove by brushing. Accordingly, the present invention is cut off for a long period of time by removing a tube of corrosion progress properly by the blow and centrifugal force, such as brushing of the corrosion product on the existing coating to produce a rust or scale, etc. are 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.
