一、前言自能源价格上涨后,国内外炼油行业都普遍重视强化保温工作。据介绍,加拿大波利萨炼厂的保温厚度增加了50％多。日本在七年中就三次修改保温保冷工程施工标准,即JIS9501—1974,1978,1980。将保温厚度增加了30～80％。以公称直径100mm的管道,介质温度250℃为例,实行强化保温后,每米管道每年可节约燃料油20.32升。
I. INTRODUCTION Since the rise of energy prices, domestic and overseas refineries generally attach importance to strengthening insulation work. According to reports, Canadian Polisa refinery insulation thickness increased by more than 50%. In seven years, Japan revised the construction standard of thermal insulation and cold-insulation engineering three times, namely JIS9501-1974,1978,1980. The insulation thickness increased by 30 to 80%. Taking a pipe with a nominal diameter of 100mm and a medium temperature of 250 ℃ as an example, 20.32 liters of fuel oil per meter of pipe can be saved annually after the strengthened insulation.
