Induction pipe bending usually produces high quality bends that are superior to bends produced by other methods, such as mandrel bending. This high quality is usually achieved by keeping a close watch on the factors that may compromise the quality of the induction bends. This article discusses some of the issues that fabricators will watch out for in order to deliver the best induction bends in your pipes.
Dents and Gouges
The pipe that is going to be bent may have surface defects, such as dents and gouges that develop due to poor handling. Such defects can compromise the quality of the induction bends because the material will respond differently to the induction process at those points that have the defects. For instance, the dented area may absorb more heat from the induction heating coils because the dents caused that area to have a thinner wall. That excess heat may cause the material to become so brittle that it will easily crack when used during an industrial application. Fabricators try to guard against such defects by inspecting the pipes thoroughly in order to select those that are free from defects caused by poor handling.
Contamination
Another factor that can lower the quality of the induction bent pipes that you have ordered is the presence of contaminants on the surface of the pipes. For instance, metals whose melting point is low, such as copper, may have penetrated the pipes during the pipe forming process. Such metals can cause surface cracks to develop outside the pipe when the pipe is subjected to intense heat during the induction bending process. Fabricators reduce this risk by subjecting the pipes to pre-bending surface treatments, such as blasting the surface of the pipe with abrasives that won't react with the metal pipe.
Air Draughts
Air is usually blown towards the cooling water spray from behind the induction-heating coil. That air helps to keep the water from cooling the pipe at the point where it is being heated before it is bent. The air draught can alter the temperature reading at the surface of the pipe being bent. This may cause the fabricator to increase the intensity of the heat in the heating coil. That excessive heat can cause the internal diameter of the pipe to exceed the heat parameters set for the bending process. The pipe can become brittle inside and crack. This problem is usually prevented by ensuring that the air draught is minimal so that it doesn't affect the surface temperature of the pipe during the induction heating process. Computer models help to predict the best air draught settings for the bending process.
As you can see, much care needs to be invested in the process of induction bending in order to reduce any defects that can result from a wide range of factors. You should therefore select the most experienced induction-bending expert that you can find so that you can ensure that all precautions will be taken to keep your pipes defect-free.
