摘要： Heat transfer tubes are provided internally with extended surfaces to improve heat transfer between a fluid within the tube and a fluid outside of and in contact with the tube. A flat sheet of metal is provided with extended surfaces which are welded to one side of the sheet, so that a tube with internal extended surfaces can be formed by bending the sheet so that it envelopes the surfaces and welding sides of the sheets together.

摘要： A method of producing welded helical seam pipe, made from steel sheet or strip which is wound into pipe formation, is disclosed. Prior to the welding of the wound steel sheet, an optically scannable reference line is applied to the steel sheet which extends parallel to and adjacent one of the edges of the sheet. The welding is effected by applying a first welding seam with a first welding head located within the pipe interior and a second welding seam with a second welding head located outside the pipe. In accordance with the invention, the optically scannable reference line is applied to that face of the sheet which forms the inner surface of the welded pipe. The thus interiorly located reference line is optically scanned so as to obtain scanning information which, through operative connection to control means, controls the welding movements or operation of both the first and the second welding heads. The inventive method is particularly suitable in the production of pipe which is tack-welded prior to finish welding. The application also discloses apparatus for carrying out the inventive procedure. This apparatus includes optical scanning means located within the pipe for scanning the reference line and means for operatively connecting the optical scanning means with the first and second welding heads for controlling the heads in dependence on the scanning information received by said optical scanning means. The procedure is also applicable to the testing of the welding seams, in which event the welding heads are replaced by testing heads, or both welding heads and testing heads are supplied.

摘要： A continuous band for use in making spiral seam tubes is made by horizontally aligning sheet metal plates in a common horizontal plane and clamping each adjacent end of the plates separately. A milling cutter is introduced in a slot formed between the adjacent transverse edges of these plates to trim and chamfer these two transverse edges simultaneously. Thereupon at least one of the clamping devices for clamping one of the plates is moved toward the other clamping device holding the other plate so that a welding joint is formed between the two transverse edges, which are then welded together.
摘要翻译：用于制造螺旋缝管的连续带是通过将金属板水平对准在共同的水平平面中并分别夹紧板的每个相邻端而制成的。铣刀被引入形成在这些板的相邻横向边缘之间的槽中，以同时修整和倒角这两个横向边缘。因此，用于夹紧其中一个板的夹持装置中的至少一个朝向另一夹持装置移动，以夹持另一个板，使得在两个横向边缘之间形成焊接接头，然后焊接在一起。

摘要： A machine for winding fin onto tubes comprises a bed having a headstock through which passes a retractable mandrel for supporting a first tube. A saddle which traverses the bed carries a strip guide, a guillotine and a welding torch. Strip is wound from one tube to a second aligned with the first, the strip is welded to the two tubes and then severed, the first tube removed, and the second tube returns with the saddle to the position occupied by the first tube.
