METAL STRIP |
| 摘要 |
Provided is a metal strip for a pipe with which the weight of a pipe can be reduced while maintaining the strength of a joint portion that tends to be structurally the weakest. A metal strip L is formed by rolling. The thickness of each of a head end portion 1a and a tail end portion 1b, which are longitudinal end portions 1, is greater than the thickness of an intermediate portion excluding the longitudinal end portions 1. The metal strips are connected to each other in series by welding, and a pipe is made by performing a pipe-forming operation. |
