<p>A method for bending pipes, where there is created a file containing known spring-back and extension properties of various pipe materials and sizes at different angles of bend; the routing of the pipe is determined on the intended site of installation of the pipe, for instance by defining the coordinates of the bending points, or by directly measuring the lengths as well as angles and planes of bend of the straight parts of the pipe; on the basis of the predetermined pipe routing, there is defined the geometrical information for the pipe, this information including the lengths of the straight parts, and the radiuses and planes of bend of the pipe angles; bending instructions for bending the pipe are created on the basis of this material information, including extension and spring-back information, calculated or measured geometrical information of the pipe as well as information of its size; and the pipe is bent according to the created bending information.</p> |
