Insulation or cooling for liquefied hydrocarbon pipelines at normal temperature and pressure

Insulation or cooling for liquefied hydrocarbon pipelines at normal temperature and pressure? The basis for heat retention and insulation, thank you
At room temperature, liquid-phase pipelines under high pressure are equipped with insulation or heat-insulating measures. Their purpose is not to retain heat or cold, but to prevent the temperature of the liquid-phase pipelines from rising due to sunlight exposure or other factors. When the temperature is high, the saturated vapor pressure of liquefied gas increases, which poses certain safety risks.
Its function is to maintain cold conditions, preventing liquefied gas from vaporizing due to heat, which could lead to increased pressure and damage to pipelines and equipment. If it is the pump inlet pipeline, vaporization will cause the pump to empty.
