Heat Tracing Systems
Course Highlights

This online engineering PDH course provides guidance on heat tracing, its different types (electric, steam, hot water), and its advantages and limitations.


The term heat-tracing refers to the continuous or intermittent application of heating pipelines, tanks, vessels or other equipment used for storage or transportation of a product (liquid, powder or gas). The purpose of heat tracing is to compensate or make up for the heat loss to the surrounding atmosphere in low ambient temperature climates. Some applications for heat tracing include; preventing fluid from freezing, maintaining process fluids at pumpable viscosities, preventing formation of hydrates and waxes in hydrocarbon liquids (oil, etc), and also sometimes to preheat part of a fluid system prior to initial startup or after a primary heating system shutdown.


The heat tracing is generally accomplished by employing electric or steam tracing and insulating both the process fluid pipe and the tracer together, using appropriate insulation materials and metal lagging. The decision between electric and steam heat tracing depends on various factors and this course outlines the pros and cons of both the methods.


This 4 PDH online course is applicable to process, mechanical and electrical engineers, operations & maintenance personnel, as well as consultants and contractors who construct, build and manage facilities involving heat tracing systems.
