A method of manufacturing a jacketed metal line is detailed herein. The method of manufacturing a jacketed metal line can include roughening an outer surface of a metal core of the line. An insulating polymer layer can be applied to the metal core, and the insulating polymer layer can include a reinforcing additive comprising: graphite, carbon, glass, aramid, short-fiber filled PolyEtherEtherKetone, mircron-sized polytetrafluoroethylene, or combinations thereof. The roughened metal core can then be exposed a heat source for at least partially melting the polymer layer; and the partially melted polymer layer and insulated roughened metal core can be ran through a set of shaping rollers.

Manufacturing techniques for a jacketed metal line

A technique for manufacturing slickline with a jacket of enhanced bonding. The technique may include roughening an outer surface of a metal core and applying an initial insulating polymer layer to the roughened core in a non-compression manner such as by tubing extrusion. The insulated core may then be heated and run through a set of shaping rollers. Thus, the grip between the polymer and the underlying metal core may be enhanced at a time following the initial placement of the polymer on the core. In this manner, processing damage to the underlying core surface which might adversely affect maintaining the grip may be minimized. Other techniques such as powder spray delivery of the initial polymer layer may also be utilized in a similar manner.
