前言强化保温是节能对策的重要环节之一。强化保温,合理选择保温材质,散热损失就大大减少,节能效果明显,经济效益甚大。目前世界上一些主要工业国家,如苏、美、英、西德、日本等,都十分重视能源问题,其中包括对原有保温管道的保温效果重新评价问题。例如日本,它十分重视保温工作,74、78、80三年接二连三修订了保温保冷工程施工标准,保温厚度比原来增加30～
Preface Strengthening insulation is one of the important aspects of energy conservation strategies. Strengthen the insulation, reasonable choice of insulation material, heat loss is greatly reduced, energy-saving effect is obvious, great economic benefits. At present, some major industrial countries in the world, such as the Soviet Union, the United States, the United Kingdom, West Germany, Japan, etc., attach great importance to energy issues, including the re-evaluation of the original insulation pipe insulation effect. For example, Japan, which attaches great importance to insulation work, 74,78,80 three consecutive amendments to the insulation and cooling project construction standards, insulation thickness than the original increase of 30 ~
