Abstract

Tube forming methods can be used to transition efficiently in producing tubes with varying thicknesses. The material used to form the continuous tube may have the same thickness along a separation plane that separates the first and second discrete sections of material, and the first and second discrete sections may each be The feed direction has a varying thickness. Using this thickness profile, a first discrete section of material can be formed as a first cylinder with varying thickness and be separated from a second discrete portion while the second discrete section is formed as a second cylinder with varying thickness. separate. In particular, the transition between the first and second cylinders can be achieved without waste and / or interruptions, resulting in cost savings and improvements in production yield associated with forming tubes of varying thickness.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 445,520, filed January 12, 2017, which is incorporated herein by reference in its entirety. Background technique [0003] Tubes are ubiquitous in industrial applications, some of the common uses include supporting wind turbines (or other mechanical equipment) and conveying fluids. It is often desirable to vary the thickness of the tube or tubes formed for a particular application. For example, in large-scale industrial applications such as the formation of wind turbine towers, the tubes used to form such towers are built to factory settings and limited to a maximum diameter constrained by delivery constraints. With the diameter of the tube constrained in this manner, it is often desirable to vary the wall thickness of the tube along the length of the tube to form a tube with desired structural performance characteristics. In particular, it i...
