如何做好设备部件的节能保温成为摆在企业目前的重要课题。因为整个设备部件的热量能耗、更换部件的耗时耗材、更换不及时等引起的损失已成为不容忽视的问题了，据核算，一个DN50—300℃的裸露阀门每年散发的热量相当于燃烧一吨燃料油的发热量。石化装置的阀门数以万计，其保温的好坏直接影响着装置的能耗和经济效益。但由于近年来加上高硫高酸油不断增加，设备与管线的腐蚀问题愈加突出。为此，中石化专门制定了《关于加强炼油装置腐蚀检察工作的管理规定》和《加上含高疏高酸原油装置设备及管道测厚管理规定》，要求对工业管道进行定点定期测厚，由于大多数管道没有保温处理或使用传统连体保温状态，定点测厚需要定期拆卸原保温层,传统连体保温层拆卸后无法恢复再次使用，这就需要开发一种便于拆装的新型可拆卸软体节能保温罩保温装置。

How to do a good job of energy-saving insulation of equipment components has become an important issue in the enterprise. Because the heat loss of the entire equipment components, the time-consuming consumables of replacement parts, and the untimely replacement of the components have become a problem that cannot be ignored. According to the calculation, a bare DN50-300 °C exposed valve emits the same amount of heat per year. The calorific value of tons of fuel oil. There are tens of thousands of valves in petrochemical plants, and the quality of their insulation directly affects the energy consumption and economic benefits of the device. However, due to the increasing number of high-sulfur and high-acid oils in recent years, the corrosion of equipment and pipelines has become more prominent. To this end, Sinopec has specially formulated the “Regulations on Strengthening the Corrosion Procurement of Oil Refining Plants” and the “Regulations on the Management of Equipment and Pipe Thickness Measurement with High Sour Acid and Crude Oils”, requiring fixed-point periodic thickness measurement of industrial pipelines due to Most pipelines are not insulated or used in traditional joint insulation. Fixed thickness measurement requires regular removal of the original insulation layer. The traditional insulation layer cannot be reused after disassembly. This requires the development of a new removable software that is easy to assemble and disassemble. Energy-saving insulation cover insulation device.
