| 摘要 | The present invention relates to the use of coupled bimetallic conduits for transporting fluids. Preferably, the bimetallic conduits are weldable conduits formed by positioning a tube (12b) formed of a material having desirable properties within a pipe (12a) formed of a commonly weldable material, with the tube (12b) having an outer diameter slightly less than the inner diameter of the pipe (12a). The pipe (12a) is compressed in a reducing operation so that the inner diameter of the pipe (12a) is reduced to a diameter that is less than or equal to the outer diameter of the tube (12b), and the ends of the resulting conduit are finished so as to be ready for coupling. The resulting conduits are positioned in opposing relation, such that an end of each of the conduits engages the respective opposing end portions of a coupling suitable for welded interconnection of the conduits. | ||||||
