Patent number: 8685493Abstract: 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.Type: GrantFiled: June 1, 2012Date of Patent: April 1, 2014Assignee: E I du Pont de Nemours and CompanyInventors: Laurence Waino McKeen, Kimberly Dawn Farnsworth, W.

Patent number: 8453740Abstract: Disclosed is a process for reducing the deposition of asphaltenes, paraffin wax, or inorganic scale in an oil well pipe by providing a system of pipes that convey any flowable medium, such as oil and gas. More particularly the system of pipes is provided with different coatings or linings for the interior and exterior surfaces of such pipes, depending on the environment in which the pipes are used. The pipes may be coated with different materials, which may be of different thicknesses, with various configurations of coatings or linings. Such coating may be on the interior and/or exterior of the pipes.Type: GrantFiled: November 4, 2010Date of Patent: June 4, 2013Assignee: E.I. du Pont de Nemours and CompanyInventors: Pidatala K.

Publication number: 20110041924Abstract: The present invention relates to the process of a system of pipes that convey any flowable medium, such as chemicals, food and in particular, oil and gas, and more particularly to a system of pipes having different coatings or linings for the interior and exterior surfaces of such pipes, depending on the environment in which the pipes are used. The pipes may be coated with different materials, which may be of different thicknesses, with various configurations of coatings or linings. Such coating may be done on the interior and/or the exterior of the pipes.Type: ApplicationFiled: November 4, 2010Publication date: February 24, 2011Applicant: E. I.

Patent number: 7870877Abstract: The present invention relates to a pipe, especially an oil pipe, having a lining comprising a fluoropolymer adhered to its interior surface and a lining formed on its exterior surface. The interior and/or exterior lining may comprise a primer layer comprising a fluoropolymer, and preferably a perfluoropolymer and an overcoat or a preformed film adhered to the primer layer. Either the overcoat or the preformed liner also comprises a fluoropolymer, and preferably a perfluoropolymer. The surface of the lining facing the flowable media, such as oil, may be a pure perfluoropolymer to provide a particularly good non-stick surface for the oil.Type: GrantFiled: May 26, 2009Date of Patent: January 18, 2011Assignee: E.I. du Pont de Nemours and CompanyInventors: Laurence Waino McKeen, Pidatala K.
