Abstract

PURPOSE: To manufacture a plastics-coated steel pipe having easily repairable and firmly bonded coating layer, and useful as an underground corrosionproof steel pipe, by using two kinds of adhesive comprising soft adhesive to the steel-side , and a hard adhesive to the plastic side.
CONSTITUTION: The surface of a steel pipe is coated with a pressure-sensitive soft adhesive having a consistency of 40W100, and then coated with a pressure-sensitive hard adhesive having a consistency of 1W20. A plastic coating material is applied thereto, to obtain the objective plastics-coated steep pipe. The soft- or hard-adhesive can be prepared by mixing asphalt, a rubber, etc. at proper ratios.
