    • A high temperature iron-chromium-aluminium (FeCrAl)l alloy tube (1) extending along a longitudinal axis (C), wherein the tube is formed from a continuous strip (3) of a high temperature FeCrAl alloy and comprises a helical welded seam (2). The high temperature FeCrAl alloy tube is manufactured by feeding a continuous strip of the high temperature FeCrAl alloy toward a tube shaping station (4), helically winding the strip such that long edges (6, 7) of the strip abut each other and a rotating tube (1) moving forward in a direction parallel to its longitudinal axis is formed, and continuously joining said abutting long edges together in a welding process directly when the tube is formed, whereby a welded tube comprising a helical welded seam is obtained.
    • 一种沿纵轴(C)延伸的高温铁 - 铬 - 铝(FeCrAl)1合金管(1),其中该管由高温的连续条带(3) FeCrAl合金并且包括螺旋焊缝(2)。 高温FeCrAl合金管通过向管成形站(4)供给高温FeCrAl合金的连续带材,螺旋地缠绕带材使得带材的长边缘(6,7)彼此邻接并旋转 在平行于其纵向轴线的方向上形成向前移动的管(1),并且在形成管时直接在焊接过程中将所述邻接长边连续地连接在一起,由此获得包括螺旋焊接接缝的焊接管。 p>
