Abstract

Un caÅ"o metálico roscado para la industria de extracción de petróleo tiene una porción roscada en su extremo con tratamiento superficial, en el cual la superficie del metal tiene una rugosidad (Ra) comprendida entre 2,0um y 6,0um, y la cual está recubierta por una capa uniforme (7) de un recubrimiento inhibidor de corrosión seco y una segunda capa uniforme (8) de un recubrimiento lubricante seco. En forma alternativa, las capas (8,9) se combinan en una capa uniforme (9) de un recubrimiento inhibidor de corrosión seco que contiene una dispersión de partículas de lubricante sólido. </P>A threaded pipe or metal for the oil extraction industry has a threaded portion at its end with surface treatment, in which the metal surface has a roughness (Ra) between 2.0um and 6.0um, and which is covered by a uniform layer (7) of a dry corrosion inhibitor coating and a second uniform layer (8) of a dry lubricant coating Alternatively, the layers (8,9) are combined into a uniform layer (9) of a dry corrosion inhibitor coating containing a dispersion of solid lubricant particles. </P>
