在热输原油管道上,保温是节能的手段之一。在长输管道中,必须的架空管段是热损失最严重之处,当采用了聚氨酯硬质泡沫保温层后,可以节约大量的热能。在计算保温层厚度时,既要考虑保温层造价、施工费用又要满足热损失最低的原则。同时,对于燃料的热价(既原油价格)也是需要考虑的因素之一。就原油的价格有如下几种:计划 In the hot oil pipeline, heat preservation is one of the means of energy saving. In long-distance pipelines, the necessary overhead pipe section is the most serious loss of heat, when the polyurethane rigid foam insulation layer, you can save a lot of heat. In calculating the thickness of the insulation layer, it is necessary to consider the cost of insulation, construction costs but also to meet the minimum heat loss principle. At the same time, the price of fuel (both crude oil prices) is also one of the factors to be considered. The price of crude oil is as follows: plan
