After the steam heat tracing installation along with the main process piping network steam from the header is distributed through a steam manifold to all steam tracers. As per the requirement High-pressure steam, Medium Pressure steam, or Low-Pressure steam flow through steam tracing piping network.

Step 2.Determine Pipe Heat Loss Find QP in Table 1 (page 2) for the nominal pipe size and insulation thickness based on ΔT. For example, for a 3" (76 mm) pipe with 2" (51 mm) insulation and ΔT = 60ºF (33.3ºC), the value for QP is 5.5 W/ft (10.8 W/m). THERMAL DESIGN- PIPES Step 3.Adjust for Insulation Table 1 (page 2) is based on ASTM C547

The principle of heat tracing dates back from the early 1900’s, when steam and fluid heat tracing techniques, were used to ensure the flow of petroleum (viscosity control) through pipelines. Although very rudimentary during the 1930’s, electric heat tracing began to appear without dedicated equipment, controls or adequate materials.

A ratio of the two resistances indicates that insulation has the greatest impact in overall thermal resistance and minor imperfections in applying insulation are minimal. R = L/k R (fiberglass)= (1) = 4.00 (0.25) R (air gap) = (0.05) = 0.299 (0.167) R (total)= R (fiberglass)+ R (air gap)

There are three ways of protecting the heat tracing system from exceeding the high-limit temperature:-1. The use of inherently temperature-safe heat tracers (self-regulating trace heaters having a PTC characteristic) that can never exceed the high limit temperature. Heat tracing standards refer to this as the product classification method. 2.

Since most steam tracing applications are for “temperature maintenance only” where the traced pipe is in a steady-state condition ( thermal equilibrium), Thermon generally uses a conductance rate which embodies both the overall heat transfer coefficient and the heat transfer area.

A heat trace system is an electrical system used to maintain or raise the temperature of pipes and vessels. The electric heating is achieved by utilizing a resistant element that is run alongside the piping or vessel. Current heat trace technology utilizes a self-regulating polymer that controls the wattage of the element.
