Which pipelines require heat tracing?
This post was last edited by sdwfsgyykai on 2018-12-6 08:09. Pipelines that require heating must be heated. The medium inside the pipe must remain in its original phase; external factors must not cause a change in its phase. When ordinary insulation is not sufficient, insulation measures must be taken. Simple examples are steam pipes, water pipes,...........................
Based on the properties of the fluid in the pipeline and your process requirements, such as preventing crystallization or condensation and caking, etc
Pipelines that are not up to standard for starting up/shutting down, with a low freezing point
Heat tracing is used to reduce heat loss; where a specific temperature is required, heat tracing or insulation is chosen as appropriate in each case
It seems that most steam condensate pipelines are equipped with heat tracing pipelines
There are very few heat tracing pipes in steam condensate pipelines; at most, insulation is added.
Pipelines that require heating usually fall into the following categories: 1) Pipelines that need to compensate for heat loss of the medium inside them from the outside, in order to maintain the temperature of the medium being transported； 2) During transportation, condensate is formed due to heat loss, which can cause corrosion or affect the proper operation of gas pipelines ； 3) During operation, self-cooling due to a sudden drop in medium pressure may cause freezing and blockage of the pipes ； 4) During switching operations or intermittent operation, the medium inside the pipe experiences a temperature drop due to heat loss; the pipe may experience solidification of the medium as it cannot be completely drained or purged ； 5) Pipelines in which crystal precipitation of the medium inside may occur due to heat loss during transportation ； 6) Pipes in which heat loss may lead to an increase in the viscosity of the transported medium, an increase in system resistance, and a decrease in the flow rate, resulting in a volume that falls below the minimum allowable value for the process ； 7) Pipelines whose conveying medium has a freezing point equal to or higher than the ambient temperature.
Pipelines that cannot achieve the required temperature of the material inside them when only insulated are all require heat tracing
