Abstract
PURPOSE: To avoid additional electric corrosion preventive processing by forming a corrosion preventive layer by spraying resin on the heat-shrinkable tube. CONSTITUTION: The joint portion is covered by a heat-shrinkable tube 4 of the first layer and a heat-shrinkable tube 5 of the second layer, which are then heated and shrunk. Polyethylene resin 6 is flame sprayed on the heat- shrinkable tube 5 of the second layer. In this way, a film having a flat surface is obtained and the adherence of the coating film with the prime material is strong, therefore it is possible to avoid additional electric corrosion preventive processing.
