ABSTRACT:
A method for applying a corrosion-protective coating, with a heat-shrinkable tube, to a joint between welded end portions of corrosion-protectively coated steel pipes, has a configuration comprising the steps of: preparing a coating implement having a releasant layer formed on the outer circumferential portion of the heat-shrinkable tube, and a heating layer formed on the outer circumferential portion of the releasant layer; positioning the coating implement so as to cover the welded portion of the joint and its adjacent portions; thermally shrinking the coating implement in a state in which the gap between the coating implement and the aforementioned portions is kept in a vacuum; and removing the releasant layer and the heating layer, whereby the aforementioned portions are corrosion-protectively coated by the heat shrinkage of the tube.
