A metal pipe melt-coated with a thermoplastic synthetic resin using an adhesive composition which contains as major components 5-50 parts by weight of an oil-soluble phenol resin, 5-60 parts by weight of an ethylene copolymer and 5-50 parts by weight of a petroleum hydrocarbon compound having a mean molecular weight in the range of 50,000 to 1,000,000.

Metal pipe coated with thermoplastic synthetic resin

There are applied in layers on the surface of a metal pipe, a rapid hardening and cure type corrosion preventive material consisting essentially of isocyanate terminated polyurethane prepolymer, amine base hardener and petroleum resin, and a reinforcing material consisting of silica sand, blast furnace slag or the like. Thus there are provided a plurality of coatings or layers on the metal pipe, which are excellent in impact resisting and corrosion preventive properties.
