    Abstract: PROBLEM TO BE SOLVED: To provide a resin lined steel pipe with end corrosive protection core used for piping and the like for snow removal, water supply, air-conditioning, fire-fighting and drainage and its manufacturing method. SOLUTION: In the manufacturing method of the steel pipe, resin lined pipe with the corrosive protection core at a tube end, which is used when connected by a coupling not having an end corrosive protection function, having an adhesive layer on an inner surface of a steel pipe or a steel pipe galvanized on its outer surface, has a polyolefin resin layer or cross-linked polyolefin resin layer on its further inner side, the steel pipe is given substrate treatment on its inner surface in advance, the substrate treatment forms a phosphate chemical conversion coating treated for grain refinement, and is provided at its end with a corrosive protection core formed by a cylindrical part having dimensions and rigidity enabling strong fitting to the end inner surface of the resin lined steel pipe and a flange part having a shape and rigidity enabling attachment, then close fitting to the end while completely covering the end face of the resin lined steel pipe, the outer surface of the cylindrical part is provided with circumferential grooves, the material is a high corrosion resistance metal, and the corrosive protection core closely fit with a rubber ring at an inner surface of its flange part is provided to the tube end.
