ABSTRACT:
A composite small-diameter tubing resistant to interaction with materials conveyed therethrough such as liquids containing alcohols or corrosive agents which includes a cylindrical outer metal conduit having a hollow central shaft extending longitudinally therethrough defined by an interior wall; and a continuous non-reactive interior tube surrounded by and positioned within the cylindrical metal conduit. The tubing can be manufactured by a process which includes the steps of a) positioning a length of non-reactive tubing having a predetermined outer diameter within an inner diameter of metal tubing of essentially corresponding length, the metal tube having an unsealed side seam, wherein the inner diameter is greater than the outer diameter of the non-reactive tubing; and b) sealing and reducing the metal tubing to an outer diameter essentially equal to the predetermined outer diameter of the interior tubing. The non-reactive interior tube may be made of a suitable polymeric material.
