Induction bending is used on large pipes such as petroleum and industrial pipelines, but can also be used in making smaller products such as springs, and farming tools. Induction is an advanced method that is preferred for bending because of its quality, precision and repeatability, which are not offered by cold bending. It is one of the most advanced among the pipe tube bending techniques known today. It is carried out by first heating up the required material and then forcing it to bend to a pre- decided radius. It generally does not require special tools, which make it cost- effective and precise. Induction pipe bending is a process when heat is used on a particular area of a metal section- pipe or tube, in order to allow it to bend easily. The heat is applied using an induction coil heated to a preset temperature to give the metal a bend of a preset radius. The process is also often referred to as hot pipe bending. Almost any metal or steel product can be used in the induction bending process, this includes metal bars, pipes and tubes, while steel is usually the metal that is used with the hot rolling process. Typical problems experienced with cold bending like wall thinning and excess ovality can be dealt with and avoided in the case of induction bending. Induction bending is frequently used today by bending applications of various kinds. One big advantage is that you can heat only that area which has to be bent without distorting or scaling the rest of the tube. Since the process involves heating a particular area of the pipe, it ensures that the distortion on the section is minimal once the bending process is completed. The amount of energy required to carry out the process is minimum that results in systems that have higher energy efficiency. This method can be used for bars, tubes and strips alike. Time cycles can be made efficient and reduced greatly in order to achieve efficient flow of work. The energy systems are also very efficient because the area to be heated is defined clearly and is controlled constantly. This allows for minimal power consumption. Repeatability is achieved by controlling the power, time and temperature. This method is highly versatile as it can be used to heat any selected metal component to a given temperature to bend it. Induction pipe bending does not require internal mandrels and sand filling, thereby saving on cost. The process does not take very long compared to the other metal bending techniques, thereby adding to its cost efficiency. The need for welded or mechanical joints is eliminated by this method which means that there is no need for smoothening the surfaces for a neat finish. The high precision bends are also carefully inspected by tube benders. Bends produced from induction bending are of great precision. Customers demand for consistency, quality and repeatability, all of which can be provided only by induction bending. It is commonly used to bend pipes and tubes for commercial, architectural, industrial and other applications in both small and large quantities.
