Impedance Pipe Heating – End Feed Systems
When configuring Banner-Day’s TraceFREE® pipe heating designs, end feed systems are the most commonly used. They are excellent for lower to mid-range temperature applications, including multiple branch piping systems.
Impedance Pipe Heating - Center Tap Systems
The TraceFREE® center tap system is typically used for longer pipe runs, frequently without branch lines, and is well suited for midrange and high temperature applications. It does not require the use of dielectric insulated pipe joints because a center tap system is electrically grounded at each end. Said another way, the voltage between the X2 cable connections on the ends of the pipe and earth ground is zero. It is this characteristic that allows impedance to be applied to a piping system carrying an electrically conductive fluid.
Impedance Heating for Molten Salt Temperature Maintenance
Over the years, Banner Day has engaged with companies to solve out of the ordinary pipe heating applications or requirements. Our TraceFREE impedance electric pipe heating systems have versatility and has proven to be an excellent choice for their pipe heating solution. Recently, Banner-Day has had the opportunity to collaborate with several organizations to support these alternative developing solar technologies. Our TraceFREE IPH center tap system is utilized due to the salt being conductive and the high temperature requirement. In a typical application, molten salt is circulated through highly specialized piping in the receiver (heat exchanger) during the day and held in storage tanks at night at 1050⁰F. Center tap systems are used for longer point to point pipe runs, do not require insulated pipe joints or dielectric flange gaskets and are grounded at each end thus being a good choice for solar applications.
Pipe Heating for Temperature Sensitive Products
Various types of pipe heating technologies are regularly employed in countless process pipe heating applications throughout industry. However, when processes involving temperature sensitive products require pipe heating, many pipe heating technologies are not up to the challenge. Too often the pipe heating technologies utilized do not provide the needed heating performance to successfully achieve the process requirements.
Impedance Pipe Heating – A Different Application
Impedance pipe heating. By now, those words probably conjure an image of long delivery lines: 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.
