Relationship between ice thickness in low-temperature pipelines and the temperature of the medium inside the pipelines
Thread Content
Under ideal conditions, there is no relationship between the ice thickness in insulated low-temperature pipes and the temperature of the fluid inside the pipes. Is there a way to calculate this, or is there an insulation coefficient for ice?

At room temperature, if insulated measures are not taken for low-temperature pipelines, freezing is a common occurrence; moreover, without insulation, there is heat exchange and energy loss. As for cryogenic media, there are many types (including liquid hydrogen, liquid oxygen, liquid argon, liquid ethylene, liquid propylene, liquid LNG, liquid CNG, …). Different cryogenic media have different thermal insulation coefficients, and there are relevant standards and professional design agencies that ensure that suitable insulation materials are chosen.
Check the heat transfer coefficient of insulation materials; the Sinopec maintenance procedures provide the heat transfer coefficient for glass foam
