Tank Heating

What is a TraceFREE® Electric Impedance Pipe Heating system?

The Banner-Day Pipe Heating TraceFREE® Electric Impedance Pipe Heating (IPH) system is designed to heat carbon steel, galvanized steel, stainless steel, or exotic metal pipe or tubing to maintain or increase the temperature of a product or material flowing through a piping system. With TraceFREE® impedance pipe heating product in a pipe can be thawed from a solid product and heated it to a desired operating temperature, gradually increase product temperature as it moves thru the pipe, or maintain a constant product temperature as the product is transported. The Banner-Day Pipe Heating TraceFREE® electric impedance pipe heating system provides operational flexibility to companies by allowing intermittent or continuous pipe heating and process operation.

TraceFREE® utilizes low voltage electricity (typically < 50 VAC) to heat the piping system. Pipe and product temperatures can be maintained from ambient to in excess of 1400°F with tight tolerances.

How does TraceFREE® Electric Impedance Pipe Heating work?

A Banner-Day Pipe Heating TraceFREE® Electric impedance system uses a low AC voltage to cause electric current flow through the piping to be heated. The secondary side of a dual wound isolated impedance system transformer is connected to a piping system, installed to be isolated from earth ground, using cable conductors connected to high strength cable lugs attached to the two ends of the impedance heated pipe.

As depicted in Fig. 1, low voltage AC current flows from the first transformer connection point (located by the tank) through the pipe to the cable lug located at the use point. The current bypasses the inline pump, isolated from impedance system current by two dielectric Insulated Pipe Joints (IPJ’s) and a bypass jumper cable. From the cable lug at the Use Point in Fig. 1, the impedance system current flows back through the return cable conductor to the TraceFREE® impedance system transformer. This transformer is grounded at the return cable conductor connection to provide a zero voltage reference for the system.

The system is controlled from the TraceFREE® control panel that manages the input power to the impedance transformer by sensing the pipe and or product temperature with a RTD temperature sensor. The RTD is typically welded to the outer surface of the heated pipe allowing the pipeline and product temperature to be maintained at the desired set point temperature.

System Types There are two types of Banner-Day Pipe Heating TraceFREE® Electric pipe heating systems:

End Feed

Center Feed

The TraceFREE® end feed system is the most common and is used with piping systems that have several branches. Excellent for both low- and mid-range temperatures, an end feed system is easier to install than a center feed system.

The TraceFREE® center feed system is used for longer systems typically without branch lines, and is best for mid-range and high temperature applications. It does not require insulated pipe joints or flange gaskets.

Are you challenged with moving viscous temperature sensitive materials?
Do you have any of these situations?

• Need to maintain constant elevated temperature from one point in your piping system to another?
• Need to raise the temperature of your material as it passes through the pipe?
• Need to raise the product from a standby temperature to an operating temperature within a defined time period?

If you have these or any related concerns or requirements, you should consider a TraceFREE® Electric Impedance Pipe Heating solution from Banner-Day Pipe Heating.

Materials flow easily through pipe with use of a Banner-Day Pipe Heating TraceFREE® Electric Impedance Pipe Heating system. The pipe heating system is engineered so the piping itself serves as the heating element, heating pipe and tubing made from:

• stainless steel
• carbon steel
• galvanized steel
• exotic alloys

Built to NEC, NFPA and IEEE standards, the electric impedance pipe heating system is designed with temperature controls that preheat and maintain pipe temperatures from ambient conditions to as high as 1400° F and higher.

Whether you’re transporting asphalts, oils, soaps, sugars or other viscous materials, a TraceFREE® impedance pipe heating system can handle the application. Material can be liquid or vapor phase.

• Heat from ambient to product use temperature.
• Increase product temperature as it moves through the pipe.
• Maintain product at a constant temperature throughout a length of the pipe.

With minimal preventive maintenance, the reliability and dependability of a Banner-Day Pipe Heating TraceFREE® Electric Impedance Pipe Heating system ensures a stable pipe heating performance with minimal life cycle cost.
