Abstract
The method for fabrication of corrosion-resistant tubing using minimal quantities of specialized material results in corrosion-resistant tubes with a reduced capital cost. In contrast, the disclosed method uses a straight weld made along the length of the tube, rather than a spiral weld that follows its circumference. The straight weld passes up and down the tube, but only on one side, or approximately 50%, of the tube. Following application of the corrosion-resistant material by straight welding, two or more tubes are joined together into an array.
