An apparatus for conveying fluid comprising a first tube and a second tube. The first tube has a first end and a second end, an inner wall and an outer wall. The inner wall defines a passage for fluid and an outer wall has at least one first receiving section for receiving an inner wail from the second tube. The second tube has a first end and a second end, an inner wall and an outer wall. The inner wall defines a chamber for receiving the first tube and has at least one second receiving section for receiving the outer wall of the first tube wherein at least one of the first tube and the second tube are drawn down such that the first receiving section and the second receiving section of the first tube and the second tube are in close proximity to each other and sealed.

1. Apparatus for conveyance of fluid comprising: a first tube having a first end and a second end, an inner wall and an outer wall, said inner wall defining a passage for fluid and said outer wall having at least one first receiving section for receiving an inner wall from a second tube wherein said inner wall of said first tube has a diameter in the range of between about 0.002 to 0.005 inch (0.0508 to 0.127 mm); and,a second tube having a first end and a second end, an inner wall and an outer wall, said inner wall defining a chamber for receiving said first tube and having at least one second receiving section for receiving said outer wall of said first tube wherein at least one of said first tube and said second tube are drawn down such that said first receiving section and said second receiving section of said first tube and said second tube are to within between about 1/100 to 1/2000 inch (0.254 mm to 0.0127 mm) of each other and sealed by welding. 2. Apparatus for conveyance of fluid as claimed in claim 1 where said first tube and said second tube are sealed at least one of said first end and said second end. 3. Apparatus for conveyance of fluid as claimed in claim 1 where said first tube and said second tube are sealed at both said first end and said second end. 4. Apparatus for conveyance of fluid as claimed in claim 1 wherein at least one of said first tube and said second tube are made of metal. 5. Apparatus for conveyance of fluid as claimed in claim 4 where said metal is selected from the group consisting of: copper, stainless steel, stainless steel alloys, steel, iron, nickel, nickel alloys, cobalt alloys, nickel/cobalt alloys, brass, copper alloys, aluminum or aluminum alloys. 6. Apparatus for conveyance of fluid as claimed in claim 5 where said first tube is made of stainless steel and said second tube is made of copper. 7. Apparatus for conveyance of fluid as claimed in claim 1 where said first tube and said second tube are sealed by Laser welding. 8. Apparatus for conveyance of fluid as claimed in claim where said first tube and said second tube are sealed by Electron beam welding. 9. Apparatus for conveyance of fluid as claimed in claim 1 where there are at least two second tubes. 10. Apparatus for conveyance of fluid as claimed in claim 9 where said at least two second tubes are at least at said first end and said second end of the first tube. 11. Apparatus for conveyance of fluid comprising: a first tube made of stainless steel having a first end and a second end, an inner wall and an outer wall, said inner wall defining a passage for fluid and said outer wall having at least one first receiving section for receiving an inner wall from a second tube; and,a second tube made of copper having a first end and a second end, an inner wall and an outer wall, said inner wall defining a chamber for receiving said first tube and having at least one second receiving section for receiving said outer wall of said first tube wherein at least one of said first tube and said second tube are drawn down such that said first receiving section and said second receiving section of said first tube and said second tube are to within between about 1/100 to 1/2000 inch (0.254 mm to 0.0127 mm) of each other and sealed by welding, where said inner wall of said first tube has a diameter in the range of between about 0.002-0.005 inch (0.0508-0.127 mm). 12. Apparatus for conveyance of fluid comprising: a first tube having a first end and a second end, an inner wall and an outer wall said inner wall defining a passage for fluid and said outer wall having at least one first receiving section for receiving an inner wall from a second tube wherein said inner wall of said first tube has a diameter below 0.125 inch (3.175 mm); and,a second tube made of copper and having a first end and a second end, an inner wall and an outer wall, said inner wall defining a chamber for receiving said first tube and having at least one second receiving section for receiving said outer wall of said first tube wherein at least one of said first tube and said second tube are drawn down such that said first receiving section and said second receiving section of said first tube and said second tube are to within between about 1/100 to 1/2000 inch (0.254 min to 0.0127 mm) of each other and sealed by welding, where said first tube is a thin walled tube made of 304 or 316 grade stainless steel. 13. A method of fluid conveyance comprising: providing an apparatus having a first tube, and a second tube, said first tube having a first end and a second end, an inner wall and an outer wall, said inner wall defining a passage for fluid and said outer wall having at least one first receiving section for receiving an inner wall from said second tube, said second tube having a first end and a second end, an inner wall and an outer wall wherein said inner wall of said first tube has a diameter below 0.125 inch (3.175 mm), said inner wall defining a chamber for receiving said first tube and having at least one second receiving section for receiving said outer wall of said first tube where said receiving sections of said first tube and said second tube are drawn down to within between about 1/100 to 1/2000 inch of each other and sealed by welding; and, directing a fluid into said passage at said first end and removing said fluid at said second end for conveying said fluid.
