What is heat tracing?

Heat tracing is a technique used to maintain or increase the temperature of pipes, vessels, and other equipment. It involves the installation of a specialized cable or heating element along the length of the equipment, which is typically powered by an electrical source. Heat tracing is commonly used in industrial plants where the flow of liquids or gases through pipes needs to be maintained to prevent freezing, crystallization, or solidification.

There are two types of heat tracing, namely electric and steam tracing. Electric heat tracing is primarily used for smaller pipes and equipment, while steam tracing is used for larger pipes and vessels. Electric tracing is further divided into two types – self-regulating and constant wattage – depending on the type of cable used.

Heat tracing offers several advantages, including the prevention of product damage, reduced maintenance costs, and improved energy efficiency. It is also used to increase process efficiency and to maintain a constant temperature in equipment that is in direct contact with the product being transported. Heat tracing is widely used in industries such as oil and gas, chemical processing, and food and beverage processing.
