摘要： Oil well pipe component comprising a threaded portion, at least part whereof is coated with a layer of a corrosion-inhibiting material, that has been applied to at least the part of the threaded portion of the oil well pipe component by means of a method comprising a cataphoresis step from an aqueous bath, said method comprising—providing the oil well pipe component comprising a threaded portion; —immersing at least part of the threaded portion of the pipe component in a cataphoresis bath comprising water and suspended particles of corrosion-inhibiting material, and provided with an anode and a cathode means, the pipe component being connected to the cathode means; —inducing a current through the bath, in order to provide the corrosion-inhibiting material with a positive charge; —depositing a layer of the positively charged corrosion-inhibiting material onto the pipe component; and—removing the immersed part of the pipe component with the layer of corrosion-inhibiting material from the cataphoresis bath and allowing the corrosion-inhibiting material to set.
