How should the range of low-temperature influence exerted by a low-temperature pipeline on adjacent pipelines be calculated?
Thread Content
I would like to ask the experts: there is currently a low-temperature propane pipeline with a design temperature of -45°C, and alongside it runs a crude oil pipeline at normal temperature, with a clear distance of around 0.3 meters between them. How should the range of the low temperature exerted by the low-temperature pipeline on the adjacent pipeline be calculated?
There must be corresponding standards for pipeline layout!
In the design of low-temperature pipeline insulation, the temperature of the insulating outer wall should be higher than the dew point temperature, usually a few degrees above zero. Under normal circumstances, it should be possible; however, it is necessary to consider the impact on crude oil pipelines in the event of a failure in heat insulation, as this affects the viscosity of the crude oil. A staggered layout can be considered.
