Abstract

3322Provided is a multiple coated steel pipe that is obtained by covering the outer surface of an anti corrosion layer which covers the outer surface of a steel pipe with a protective layer that has adequate adhesiveness and releasability. Specifically provided are: a multiple coated steel pipe which is obtained by covering the outer surface of a steel pipe that serves as a base with an anti corrosion layer that is composed of a polyethylene resin layer and with a protective layer that is composed of a polypropylene resin layer and serves as an upper layer of the anti corrosion layer; and a method for producing the multiple coated steel pipe. The polypropylene resin that forms the protective layer is a copolymerized resin which contains 19 23% by mole of an ethylene component and has a melt flow rate of 0.53 0.60 g/10 min. The shear viscosity of the polypropylene resin at 280°C is from 1.7 × 10 Pa·s to 2.0 × 10 Pa·s as measured at a shear rate of 10/sec and is from 5.3 × 10 Pa·s to 6.0 × 10 Pa·s as measured at a shear rate of 100/sec.
