Abstract:
The present invention relates to a vessel, in particular a pipe, especially an oil pipe, having a preformed film adhered onto the interior surface of the pipe, the interior surface of the preformed film reducing the deposition of at least one of asphaltenes, paraffin wax, and inorganic scale by at least 40% as compared to the interior surface of said oil pipe without said preformed film being present. In a preferred embodiment, the preformed film is adhered to the interior surface of the pipe with a primer layer with an optional barrier layer between the primer layer and the preformed film.
