    摘要： A flat tube for use with a heat exchanger. The flat tube including wide sides, narrow sides, an inner insert, a wall that at least partially forms the wide sides and the narrow sides, and the wall is configured to be produced from a punched-out blank. The flat tube further includes an introduction bevel in order to facilitate introduction of the inner insert. The introduction bevel includes at least two bent-down projections at an end of the flat tube. The at least two projections extend over portions of at least one of the wide sides and the narrow sides, and it being possible for the at least two projections to be separated off after the introduction of the inner insert.

    摘要： Provided is a method for producing a welded steel pipe having excellent buckling resistance. The method for producing a welded steel pipe according to the present embodiment includes steps of: preparing a welded pipe, and expanding the welded pipe over the entire length thereof by using a pipe expanding head such that an undulation wavelength ratio D defined by Formula (1) is not more than 0.8, or not less than 1.8: D=p/λ  (1), where p is an undulation wavelength in the axial direction of the welded steel pipe, and λ is a Timoshenko's buckling wavelength as defined by Formula (2): λ=3.44×(r×t)1/2   (2), where r is an inner radius of the welded steel pipe and t is a wall thickness of the welded steel pipe.
