Insulation of tar processing pipelines
Thread Content
Let me ask you, but when the outside temperature can reach minus 40 degrees, can tar processing still be done? If it can be built, what method should be used to insulate the pipes? Is the energy consumption and investment of electric heating high? For steam tracing, how many tracing pipes should be used and how thick the insulation layer should be? Especially for tar, industrial naphthalene and asphalt pipelines, please give me some suggestions. Anyone who has done similar projects hopes to provide reasonable suggestions. Thank you!
This post was last edited by pecker on 2010-4-10 08:22 The temperature outside the pipeline is as high as 40°. Why can't tar processing be carried out? The temperature at which tar is processed is higher than this temperature. You should question the impact of high external temperatures on tar processing conditions. In fact, such extremely high temperatures rarely occur. As for the thickness of the insulation layer, it depends on the insulation material you use, the tar processing temperature, etc. The specific thickness is determined by calculation. BTW: It is recommended that the poster use standardized language to make statements, and do not use the term "heat tracing".
Pipes should be insulated with thermal oil jackets
Oils with a high freezing point (asphalt, naphthalene, anthracene oil, etc.) require heating of pipelines (tracing pipes, steam jackets, electric heating, etc.), while oils with a low freezing point only need to insulate the pipelines.
The minus 40 degrees you mentioned may mean high energy consumption. It is recommended that you use a steam jacket or a thermal oil jacket for insulation. The insulation thickness should be 100mm. You can also ask the design institute.
2# pecker It is possible to reach minus 40 degrees. Is there anything wrong with the statement of "pecker"?
2# pecker See clearly before questioning others. The poster said it was "forty degrees below zero".
