    Abstract: The present invention relates to a process for adhering a preformed polymer liner to the surface of a pipe by induction heating the pipe. The liner may comprise a fluoropolymer. The liner may be applied either to the interior surface or the exterior surface of the pipe. The invention is particularly useful for adhering a liner to the interior surface of an oil well pipe. Thus with the induction heating process of present invention, it is possible to adhere a preformed liner to the interior surface of an oil well pipe which is capable of reducing-to-eliminating the deposition (buildup) of one or more of the asphaltenes, paraffin wax, and inorganic scale on the interior surface of the oil pipe. Preferably, this reduction is at least 40%, preferably at least 50% or more, for at least one of these materials as compared to the unlined oil pipe, and more preferably at least 40% for all of them. In one preferred embodiment of the process, the peel strength of the preformed liner adhered to the surface of the pipe is at least ten pounds force per inch (10 Ibf/ in). In other preferred embodiments of the process, either a primer or an adhesive aid is used in adhering the preformed liner to the surface of the pipe.

    Abstract: Embodiments of a method and a mould for producing a concrete pipe comprising a basic body made of concrete and a plastic inner pipe for conducting a liquid. The method comprises introducing a mould core into the plastic inner pipe, introducing the plastic inner pipe into an outer mould and pouring concrete into an intermediate space between the outer mould and the plastic inner pipe to form the basic body. After the concrete has solidified, the plastic inner pipe remains as inner formwork in the basic body made of concrete and the mould core is removed.

    Abstract: The present invention relates to a preformed liner of tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer adhered to the surface of a pipe, and in particular, an oil well pipe, without the need for either a primer layer or an adhesive. The liner comprises an effective amount of metal powder which provides adhesion between the liner and the surface of the pipe. The present invention also relates to a process for making such pipe, where in a preferred embodiment, the liner is co-extruded to form an inner layer and an outer layer. This co-extrusion embodiment is particularly useful in applications where high purity is necessary. In this case, the inner layer comprises an effective amount of metal powder and the outer layer is pure tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer.
