Regarding the issue of pipeline insulation thickness
Thread Content
In a project, I habitually chose a insulation thickness of 50 mm for a steam pipe during the design phase; however, during trial operation, it was found that the insulation effect of this pipe was very poor and its heat loss was high. I would appreciate it if someone with expertise could advise me on how to recalculate the insulation thickness for this pipe, and indicate which standards provide relevant guidelines :(Urgently needs to be resolved)~~~~
It generally depends on what kind of insulation material is used; this manufacturer should have the relevant data.
1. The thickness required can be determined based on the heat loss associated with the insulation material you choose; there are GB standards for insulation selection – download them and take a look
The insulation thickness for the steam pipes has been chosen to be 50 mm, which is a bit thin. The chemical process design manual contains the calculation methods. First select the insulation material, then calculate.
GB50264-97 Code for Design of Thermal Insulation of Industrial Equipment and Piping – you can refer to the following
The same question; I’ll also learn* it
Take a copy of \"98T901+ Insulation for Pipes and Equipment\" and have a look
