Banner-Day Pipe Heating


The origins of chocolate, which is derived from the Theobroma cacao tree, stretch back at least 4000 years. The plant is believed to have originated in the Amazon or Orinoco basins in South America and was regarded by the Aztecs as being of divine origin.

Normally chocolate is held in storage between 110 and 120°F and will remain in a fluid state down to approximately 88°F. However, as the temperature of chocolate drops, the fluid viscosity increases rapidly. Too much heat causes damage (burning) and insufficient heat allows the material to become solid; therefore, consistency is vital for process heating.

Impedance pipe heating. By now, those words probably conjure an image of a long delivery line: a stainless tubing line in a food plant, or a carbon steel line in a production facility. In either case, just a simple delivery line, taking product from a tank or storage area to a use point. Is this the only place to use impedance? Is it relegated to fixed delivery lines and nothing else? Of course not! While it is a simple and effective method of heating pipe, it can also be a flexible one. 

Over the last several newsletters, we have addressed a variety of topics on many different aspects of an impedance system. We have seen how it works, examined the different components of a system, and looked at the maintenance requirements. Now, we will look at a practical application of an impedance system, and the benefits of impedance heating over other methods. 

While impedance heating is an appropriate method to maintain and heat pipes, it is not always the best option. So how do you know when to consider and apply impedance pipe heating? Here are five areas where impedance heating is always an excellent choice: 

Previous articles have focused on specific applications for impedance pipe heating. Now we would like to address a less conventional use: transporting an electrically conductive material.
