一、引言 就广义而言,泄漏存在于各系统。在煤气储配系统,泄漏现象不仅会污染环境,造成直接的经济损失,它往往是一根导火线,直接、间接地引起中毒,爆炸及着火事故。 近年来,国外工业界十分重视泄漏问题。据英国皇家化学工业公司对环已烷工程进行分析,发现其装置与管道部分因泄漏造成的损失达1700万日元/年。为此,对泄漏事故进行了彻底的检修,使泄漏的损失率降至原十分之一。从而大大降低了二次爆炸及

I. INTRODUCTION In a broad sense, leaks exist in various systems. In the gas storage and distribution system, the leakage phenomenon not only pollutes the environment and causes direct economic losses. It is often a fuse that directly or indirectly causes poisoning, explosions and fire accidents. In recent years, foreign industry has attached great importance to the issue of leakage. According to the analysis of the cyclohexane project by Royal British Chemical Industry Co., Ltd., it was found that the losses caused by the leakage of the device and the pipeline part amounted to 17 million yen per year. For this reason, a thorough overhaul of the leakage accident was carried out, and the leakage loss rate was reduced to one-tenth. Which greatly reduced the secondary explosion and
