A joining sleeve configured to connect internal liners of two internally lined pipe sections across a welded pipe section joint and a method of use is disclosed. The joining sleeve comprises a sleeve body having a first end and a second end, the first and second ends configured to couple with opposing ends of first and second internal liners respectively. A collar is disposed around the outer surface of the sleeve body, the collar having a first retracted condition in which it has a first outer diameter, and a second expanded condition in which it has a second outer diameter, larger than the first outer diameter.

Apparatus and method for lined pipe welding

A method for joining functional components with at least a thermoplastic components to thermosetting composites with at least some thermoplastic surface. The thermosetting composite has a functional thermoplastic surface layer attached by a process of selection of a compatible thermoplastic, heating the combined materials to allow migration of uncured thermosetting polymer into the thermoplastic polymer, then cooling the combined materials to provide a strongly attached thermoplastic surface. The thermosetting composite component may have a polymeric material coating. The present invention subsequently relates to the joining of the functional component and thermosetting polymer composite components, using high-speed oscillating relative displacement or high-speed continuous relative displacement.

Welding of functional components to polymer composite components

A method of creating a functional utility-surface on a thermoset composite component, including the steps of: fixing the position of a cured thermoset polymer composite component, the thermoset polymer composite component having a thermoplastic polymer surface layer attached to at least a portion of one surface thereof, the thermoset polymer composite component being fixed in position to allow access to the thermoplastic polymer surface layer; and shaping the thermoplastic polymer surface to form a functional utility-surface.

Functional surface shaping techniques for polymer composite components

A method of manufacturing a composite sandwich structure, the method comprising a preform assembly method. The method comprises providing a preform () comprising at least two sheets () connected by a plurality of extensible threads (), and affixing to the outer face of each sheet (), a face sheet (). The adhesion is by a film adhesive () placed over the respective sheets (), and the preform () is subjected to pressure or heat to set the film adhesive (). The method further comprises a method of molding a composite sandwich structure, the method comprising placing a preform () in a mold (), creating pressure differentials between respective chambers () within the mold (), feeding a resinous compound into the mold (), and allowing the resinous compound to set and cure. The invention also provides composite sandwich structures made in accordance with the methods.
