摘要

"The process of obtaining superfu00eccies tubular rough for lifting and disposal of oil ultraviscoso lubricated with water.The present invention relates to a process for the production of hydrophilic surfaces and / or oleofu00f3bicas capable of preventing the adsorption of oil in metal surfaces used in its transportThe ten.More specifically, the present invention obtains these surfaces by increasing the surface roughness of the steel through a mechanical process, preferably grinding.That causes the reduction of the contact angle and the consequent reduction of oil from adhering on the metal surface, which could lead to obstruction of the area of the section.Undermining or obstructing the transport. Thus, the surfaces obtained are likely to be employed in piping for transporting heavy oil by using the technique of core flow.It is important to note that the process does not require the use of chemical reagents and also that the treated surface does not suffer wear by the flow of oil over time.Maintaining its hydrophilic character / oleofu00f3bico and preventing the adhesion of oil on the surface, which allows the line of pump can be used for a long period.
