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.
