Pipeline Heating

Electric heat tracing utilizes the heat generated by electric heat tracing products to compensate for the heat loss from the pipe, container, tank, etc., maintaining the temperature of the corresponding medium to meet the process requirements. Accurately calculating the heat loss of the pipe, container, tank, and other process equipment is crucial for precisely maintaining the temperature of the medium.

Calculation of Heat Loss for Pipes and Fittings

This document outlines the calculation of heat loss for pipes and fittings, a crucial consideration for ensuring the efficient operation of various systems, including pipelines and vessels.

1. Determination of Process Parameters

Accurate calculation relies on correct determination of various parameters. These include: TW: Temperature of the medium required to be maintained within the pipe, container, or tank. d: Diameter of the pipe or surface area (S) of the container. δ: Thickness of the insulation material. TH: Environmental temperature (local minimum temperature). Environmental conditions: Indoor or outdoor, above ground or underground. Calculate the temperature difference (△T) between the maintained temperature (TW) and the environmental temperature (TH). △T = TW - TH.

2. Calculation of Heat Loss for Pipes

The heat loss (Q) for a pipe can be calculated using the following formula: Q = q × f × e × h

Q: Actual required heat tracing capacity.

f: Insulation material coefficient (refer to Table 1).

q: Heat loss per unit length of pipe under baseline conditions (obtained from tables based on process parameters - contact Shenhui for details).

e: Pipe material coefficient (refer to Table 2).

h: Environmental coefficient (refer to Table 3).

Calculation of Heat Loss for Pipe Valves

Gate valve: Typically experiences 1.22 times the heat loss per meter of the connected pipe.

Ball valve: 0.7 times the heat loss per meter of the connected pipe.

Butterfly valve (throttling valve): 0.5 times the heat loss per meter of the connected pipe.

Floating ball valve: 0.6 times the heat loss per meter of the connected pipe.

Determining the Power and Length of the Electric Heat Tracing Cable:

Select an appropriate electric heat tracing cable based on the heat loss and required medium temperature. The maximum temperature maintained by the cable must be higher than the medium temperature. If the unit length heat loss exceeds the rated power of the heat tracing cable (i.e., the ratio is greater than 1), apply the following modifications:

a. Ratio greater than 1.5: Employ two or more parallel heat tracing cables. The cable length equals the pipe length multiplied by the number of cables.

b. Ratio between 1.1 and 1.5: Consider using a winding method (illustrated in the left diagram). Calculate the winding pitch based on the ratio of heat loss to cable power. Refer to tables for pitch values. The cable length is calculated as pipe length multiplied by the ratio.

Modify insulation material or thickness.

Applicable Scope:

This calculation method is applicable for heat tracing in various applications, including: Oil pipelines, Firefighting pipelines, Potable water pipelines, Solar water pipes.
