摘要 |
<p>PROBLEM TO BE SOLVED: To provide a titanium welded pipe capable of obtaining the titanium welded pipe in which a sufficiently large surface area is secured and a high efficiency of heat exchange is provided, and to provide a method for manufacturing the titanium welded pipe.SOLUTION: A titanium welded pipe provided with rugged surface is formed by abutting edge parts of the titanium plate against each other to weld the edge parts and has a plurality of protruded parts and recessed parts formed on the surface. Therein, a diameter of the titanium welded pipe is made to be 13 mm or more and the average height of the protruded parts existing on positions separated by 9 mm or more from the center of welded beads is higher than the average height of the protruded parts existing in the range less than 9 mm from the center of the welded beads.</p> |
