摘要： PURPOSE:To remarkably reduce a residual strain of a resin layer caused by thermal shrinkage, by coating an outside surface of a corrosion preventing layer with a special adhesion preventing agent which shows a low shear strength at a high temperature but a high shear strength at an ambient temperature. CONSTITUTION:A surface of a steel pipe 1 is coated with an anticorrosion layer 11 including a plastic film as a primary coat. An adhesion preventing layer is formed on the surface of the anticorrosion layer, by applying an adhesion preventing agent onto the surface with a coater 6. The adhesion preventing agent is, for example, a high melting point wax, an apliphatic hydrocarbon mixture or a mixture of these substances with a copolymer of polyethylene and polypropylene. This adhesion preventing layer has the feature that its shear strength is low at a high temperature but high at an ambient temperature.

摘要： PURPOSE:To form a shark skin like embossed pattern on an outer surface of a coated plastic by mainting a temp. in the vicinity of an extruding port lower than a plastic temp. in preparing the plastic coated steel pipe. CONSTITUTION:After the plastic 8 is filled in a plastic storage chamber 9 within a die 6, a heater 13 is operated to heat to an extruding temp. Subsequently, in order to control a height and a pitch of the embossed portion formed on the outer surface of the plastic coated steel pipe to a desired value, a cooling air blowing apparatus 14 is operated to initiate the cooling of a lip portion 12 so as to adjust the temp. differential between the lip portion 12 and the plastic in the storage chamber 9 to an objective value. Then, if the coating of the plastic to an original steel pipe 5 is initiated according to a conventional method of an extrusion method, the shark skin like embossed pattern having a predetermined height and a pitch is formed on a surface of the coating layer. As described above, the inexpensive anti-slip embossed pattern is formed on the surface of the plastic coating.
