一、钢质贮罐底板外侧的腐蚀贮存石油产品和其它流体的各类贮罐是调节和均衡生产所必需的。据说美国就有贮罐数百万个,足见数量之多。大多数地面贮罐用钢铁制造,罐底常由普通碳钢钢板搭接焊成,与特制的罐基础直接接触。作为流体容器,对钢质贮罐安全运行威协最大的致命性事故是底板腐蚀穿孔而泄漏。日本报导,一般在建罐七年后开始出现罐底腐蚀穿孔,而十至十五年后穿孔次数急剧增多。我国
First, the corrosion of the outer steel tank bottom Storage Petroleum products and other types of fluid storage tank is necessary to regulate and balance the production. It is said that there are millions of storage tanks in the United States, which shows that as many as many. Most tanks on the ground are made of steel, and the bottom of the tank is often joined by conventional carbon steel plates and welded directly to the special tank foundation. As a fluid container, the largest fatal accident in the safe operation of steel storage tanks is corrosion and perforation of the floor. Japan reported that corrode perforation of tanks began to occur seven years after its construction, and the number of perforations tended to increase sharply after ten to fifteen years. My country
