Is insulation required for the pressure relief lines of liquid hydrocarbons?
Thread Content
The low-temperature pipeline leading to the safety valve of the gas separation unit is not insulated at present, but some of the low-temperature pipelines in the catalytic complex are insulated. I seek guidance from experts – are there any specific regulatory documents or similar materials available?
Insulation can also be considered as heat retention; it’s done for safety reasons
Low-wattage pipelines do not require insulation, as the temperature of the fluid is not high and does not vary much.
Insulating the liquefied gas pressure relief line actually hinders heat exchange with the external environment of the pipeline, making it difficult for the frost that forms inside to melt. . . As far as I remember, the entire low-voltage system of ours has no insulation at all
Heat is released under pressure, while heat absorption is required to relieve pressure; insulation, on the other hand, hinders heat absorption, which can easily lead to condensation in the pipelines
Behind the safety valve, it is necessary for the medium to absorb heat in order to dissipate and vaporize fully; insulation or cooling is definitely not required.
The pressure relief line for gas does not require insulation, as it absorbs heat during release.
