The term heat tracing refers to the continuous or intermittent application of heat to pipelines or tanks to compensate for ambient heat loss.

Among the main uses of heat tracing;

• Freeze protection,
• Viscosity control,
• Keeping fluids at process temperatures,
• Preventing gas condensation,
• thawing etc. prevention of separation of liquid components

• Freeze protection of piped water,
• Transfer of molten process chemicals such as phosphoric acid, sulfur, and p-xylene
• Low-viscosity maintenance of pumped fluids including petroleum products, vegetable oils and syrups
• Rafinerilerde yakıt gazının yoğunlaşarak istenmeyen yanmaların engellenmesi,
• Preventing the condensation of moisture in natural gas transported in pipes,
• Prevention of freezing of control valves and compressor damage,
• Prevention of condensation for prevent wet hydrogen sulphide from causing high corrosion.

Heat tracing falls into two main sub-categories.

• Electric Heat-Tracing Systems
• Fluid Heat-Tracing Systems
