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.
