Abstract
A tubular structure (10) including an expanded fluoropolymer material having an outer surface (12), an inner surface (14), and a wall (16) therebetween. The wall (16) defines a channel (18). A hose assembly (100) includes a tubular inner liner (110) formed of the expanded fluorocarbon polymeric material having an outer surface (112), an inner surface (114), and a wall (116) therebetween defining a channel (118). The hose assembly (110) further includes at least one outer liner (121) disposed about the outer surface (112) of the tubular inner liner (110). A method of making a tubular structure (10) formed of the expanded fluoropolymer material includes the steps of extruding a fluoropolymer tubular structure (10) having an outer surface (12), an inner surface (14), and a wall (16) therebetween defining a channel (18) on an extruder having at least one barrel, at least one screw, at least one mandrel, and at least one die. The method further includes the steps of applying a vacuum to the outer surface (12) to prevent the tubular structure (10) from collapsing and polymerizing the tubular structure (10). A method for constructing a hose assembly (100) includes the steps of extruding a fluoropolymer tubular inner liner (110) and disposing at least one outer liner (121) about the tubular inner liner (110).
