Abstract

The invention relates to a method for performing material tests for pipes made of steel, which pipes are to be treated with heat that influences the mechanical properties, wherein in a first process step a seamless or welded pipe is produced, which, after the production, is fed to a heat treatment installation for influencing the mechanical properties in a second process step and from which a specimen for determining the mechanical properties is taken in a subsequent third process step. The third process step being omitted, a specimen is taken from the pipe already after the first process step of the production of the pipe and initially only said specimen is fed to a heat treatment corresponding to the pipe to be treated, and subsequently the mechanical properties are determined and compared with the required properties. Then the pipe from which the specimen was taken is released or blocked for the machining of the pipe ends and for the subsequent second process step of the heat treatment.

Abstract

The invention relates to a method for producing welded pipes from steel, in which strips or metal sheets are formed into a pipe provided with a longitudinal or helical slot and the abutting edges of the slotted pipe are welded together, wherein the process parameters for production of the pipes are specified on the basis of previously ascertained material properties and geometry of the strips or metal sheets. Before the forming process, the strip or metal sheet is subjected to an uninterrupted, continuous or discontinuous test for inhomogeneities over the length and width, an integral characteristic value for the material property of the strip or metal sheet is formed from the measured values, a measure of the homogeneity of the material properties relating to the length and width of the strip or metal sheet is derived from the variance in the measured values for the various measurement points and, in the event of deviations in the measured values exceeding previously specified limit values, the process parameters are reset and/or the strip or metal sheet is subjected to a homogenisation process prior to the forming process.

Abstract

The invention relates to a method for monitoring the production process of steel, longitudinally seam-welded heavy-duty pipes by means of the UOE method, wherein in a first step, a flat sheet metal is formed into a U-shape on a press having an open mould and subsequently, said U-shape is modified on a second press with a closed mould to form an O-shaped slit pipe, the pipes are calibrated after being welded on the inside and outside by cold expansion (expansion). The temperature distribution in the shaping area of the sheet steel or the pipe which is to be shaped is thermographically registered during at least one of the three shaping steps and the obtained thermal image is used to evaluate the process state.

Abstract

The invention relates to a method for producing fiber-wrapped steel pipes having a multi-layer corrosion protection sheathing as a coating substantially over the entire pipe length, wherein in consecutive layers a primer, an adhesive, and a cover coating are applied onto the pipe and the pipe is provided with an at least one-layer fiber wrapping in order to delay or prevent the propagation of a developing crack. In order to design the method for economically, it is provided that the fiber wrapping is applied onto the pipe already during the coating process as part of the corrosion protection sheathing of the pipe in a common step at the same time as the application of the cover coating.

Abstract

The invention relates to a method for bending a plane metal sheet to be shaped into an open seam tube, in a bending press (11) comprising an upper tool fixed in the press frame (4) and having a contour corresponding to the bending contour to be achieved, and a vertically mobile lower tool (3) arranged opposite the upper tool (1). The edge strip (3) of the metal sheet fixed in the press frame (4) is bent between said tools in a working step in order to create the desired edge contour. At the beginning of the bending process, the working surface of the lower tool (3), which comes into contact with the lower side of the edge strip (3), takes its bearing in a flat manner in the form of a Hertzian compression. In order to prevent the formation of ridges and plastic deformations or crushing, said flat contacting is to be maintained at a minimal distance from the edge of the metal sheet, at a constant distance therefrom in relation to the point of application of force (P), during the entire bending process, by means of a co-ordinated horizontal and vertical movement of the lower tool (3). The bending press (11) provides a constructive solution for carrying out said method.
