At t
24、he point during its passage through the mill that the tube becomes fully formed, it is welded. HF currents are induced into the tube by an induction coil through which the tube passes. The current is confined to the surface of the tube which causes the edges of the strip to reach welding temperature
25、. These edges are forced into contact with each other by pressure rolls and a perfectly formed weld is achieved. No filler wire is used and the resultant weld is perfectly uniform. The external fin from the weld is removed by planing in the next section of mill before the tube passes through a final
26、 series of sizing rolls, which gives its final shape. This continuous operation is carried out at high speed. In this way, the HF seam welded tube benefits from the properties of the initial strip, such as a wide variety of potential alloys and mechanical properties are available. Because of the for
27、ming technique used, the seam welded tube also benefits from specific properties. Thin wall and/or large diameter tubes can be obtained. Different shapes can be produced, from the most frequently used ones to special order shapes. Various finishes can be obtained. Standard tubes are produced with a
28、bright finish. Other finishes available are: mill finish, anodized matt or bright in many colours. Tubes can also be supplied painted. Various patterns are available that can be embossed into the surface of the tubes. Due to the great variety of patterns available, the user is advised to contact the
29、 supplier for further information. The external fin is removed by planing. By special order, the internal fin can also be removed. Due to the great variety of tubes available, the user is advised to consult the supplier with regards to any new application of HF seam welded tubes. 1 Scope This Part o
30、f EN 1592 specifies the technical conditions for inspection and delivery of HF seam welded aluminium tubes. It is applicable to HF seam welded tubes obtained by forming cold-rolled strips. It is applicable to aluminium tubes produced from uncoated aluminium strip, as well as to tubing that is pre-la
31、cquered, pre-painted or pre-anodized prior to forming. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. F
