摘要
It decreases stabilizes and in the element tube and the trouble at the time of pulling removal processing which forms the helical rib by making pulling removal schedule proper administering reform, making the formation direction of the helical rib which accompanies that optimum, furthermore according to the element tube, it is the production method of being possible to form the helical rib, before the pulling removal processing which forms the helical rib the trouble at the time of pulling removal processing which forms the helical rib of the internal rib attaching metal tubing, it bends, it decreases stabilizes and it is possible to form the helical rib. From the fact that compactibility and the quality which are superior as a metal tubing for the boiler are had, it can correspond to large increasing capacity and hot high pressure conversion of the boiler the internal rib attaching metal tubing which is obtained, sufficiently.
