Interesting facts about induction pipe bending
Induction pipe bending is a process where pipes and tubes are heated to a specific temperature, usually between 800 degrees and 990 degrees centigrade where they are twisted and bent under this condition. The temperature is, however, reliant on the material used and diameter/ thickness. An induction heating coil used at a very high frequency aids this process and ensures the production of high quality pipe bends. This is not to be confused with hot rolling which involves changing the thickness and shape after heating it to a critical temperature.
Benefits of induction bending--Throughout the years, Induction pipe bending technology has evolved and advanced with improvements in the ability to create new and distinct shapes and dimensions such as small diameter bending. The process has also been highly automated making precision control easier. These advancements in precision control allow for accurate heating and cooling resulting in a more constant quality and shape. The latest technology has enabled the creation of multiple curves for structures and has brought about free design of a wide range of items such as beams and arches for railway stations, stadiums, schools and bridges.
This technology, with its numerous applications, has more advantages over cold bending as it is extremely accurate in processing. Furthermore, hot bending ensures that any spring back that might affect the angle or bend radius is minimized to provide dimensional accuracy, free shaping and reduces the need for a bending die to process small angles and complex bends.
In addition, Induction bending technology in bends is preferred over use of elbows and this reduces the cost of labour in pipe construction. It also cuts down on welding, inspection and power costs as it reduces the number of welds required. The quality of pipes is significantly improved as defects found in pipes are usually from welds breaking.
Due to the cutting edge technology, pipes produced are in accordance with all the required specifications, customisations and optimal use for material design and manufacture.
Application of induction pipe bending—the process of bending can be used for a wide variety of applications. It uses any type metal or alloy such as steel to create all types of pipes sections. In typical circumstances, the technique is mostly used for building petroleum pipelines, smaller pipe sections such as farming tools and heavy machinery piping systems. It is also used to create architectural designs and shapes that require high precision.
