A conductive resin coated steel pipe and an extrusion molding method for
the steel pipe capable of using filler instead of carbon black and not
only lowering a production cost but also further increasing an
attractiveness; the resin coated steel pipe, wherein a regenerated resin
(3) such as polyethylene, ABS, AAS, and the outer peripheral surface of a
thin-walled steel pipe (2) is coated with polypropylene, and a conductive
resin (4) such as polyethylene, ABS, AAS, and polypropylene mixed with
filler on the outer peripheral surface of the coated resin (3) is axially
uniformized in cross section by a double coated structure where the
portion (4b) thereof having a wall thickness and a width necessary for
developing the conductivity thereof are provided at one or more positions
in the circumferential direction of a pipe body and the entire outer
peripheral surface thereof is coated thinly with the resin.
