How are heat tracing pipelines for ordinary materials constructed? Is that book described? Thank you
Reference can be made to SH3040-2002T Standard for the Design of Pipes Accompanying Petrochemical Pipelines and Jacketed Pipes
A separate thin pipeline is installed along the main pipeline to supply steam, and then both are insulated together.
It can be heated with steam or electric heating.
Generally, red copper pipes are used in parallel with the pipes that require partial heating, and then they are covered together with insulation material
The pipe heating methods I have come across include steam heating and hot water heating; ordinary 20# steel is sufficient for this purpose. The diameter of the heating pipe is determined based on the diameter of the pipe that needs to be heated, and this information can be found in the \"Process Pipeline Installation Design Manual\"
There are several types of heating methods, including electric heat tape heating, steam jacket heating, steam pipe heating, and hot water heating. Depending on the temperature required for your material, materials with high freezing points such as caprolactam and heavy oil are heated using steam jackets; if the material is heat-sensitive, hot water jackets are used for heating. For materials for which a lower temperature is sufficient, pipe heating (steam pipes running parallel to the material) can be employed. Electric heat tape heating has been mentioned quite often in recent years, but it isn’t widely used in practice – this is mainly due to lack of awareness among users, as well as its relatively high cost.
