From Beginning to Advanced: Blogs on Industry and Manufacturing

Greetings! My name is Adam. I work in the advertising industry as a brand developer. I also teach surfing lessons and spend a lot of time volunteering with an animal hospital. When I was on a gap year, I took a job in a pen factory. Through that experience, I learned a great deal about how pens were made, but I also learned a lot about industrial work and manufacturing in general. In this blog, I plan to write about all aspects of these topics, and I hope that this information is interesting and informative to you. Please, grab a tea and start looking around. If you like my blogs, share them. Thanks.

Key Requirements for Induction Bending

by Daniel Wilson

Induction bending has fast gained popularity in the industrial world as one of the most advantageous pipe bending techniques in the market. In induction bending, electricity is used to create a beam of heat in induction coils. This heats up a specific region along the metallic pipe as an arm arrangement gradually applies specified pressure on the pipe to bend it as necessary. Induction bending creates smooth bends with uniform material characteristics along the bend. Induction bending also results in far stronger bends and more bend radii can be achieved.

While the above may convince anyone looking to bend large-scale pipes the induction way, there are several requirements that must be met before induction bending is considered suitable for your pipes. Here are some of those requirements.

Surface

The pipe or steel tube must have specific conditions for proper induction bending to occur. For a start, contaminants such as rust and grease should be thoroughly removed from the surface of the steel pipes. Such contaminants may alter the metal properties and lead to several failures during bending. You can consider methods such as sandblasting to thoroughly eliminate such contaminants. Metals to be bent by induction should not come in contact with low melting point metals before or even during transportation to the induction bending facility. These are metals such as copper and zinc. The presence of these metals may lead to uneven heat distribution along the bend, which can affect the quality of the bends.

Physical qualities

Foremost, only pipes of specified thicknesses can be bent using induction bending. During induction bending, high frequency heat-bending results in wall thinning at the extrados of the pipe. This is why the benders specify particular thicknesses for bending. The thickness of the pipe will also determine the acceptable bend radius.

The tensile strength of the metal may also be tested by the induction benders using specified instruments. This, together with the results of an impact test, tells the benders various acceptable values for the bending of your metal.

Chemical qualities

Induction bending may not be very effective if your pipe is made of varying materials with different chemical properties. The benders may recommend chemical tests on your material to ascertain that the metal has uniform properties along the intended bend. Several chemical tests may be done on the metal including spectrographic and mass analytic tests.  Remember, pipes to be bent by induction should not have previous repair welds or circumferential welds anywhere along the raw material because those are considered areas of weakness.
