近年来由于石油化工、城市煤气等工业向大型化发展,球型容器的使用也日趋增多。通过这些年来在建造和使用方面的实践(例如开罐检查中发现的一些问题),反映了目前球形容器在选材及建造中存在的一些问题,也造成了一些错觉。因而有必要对球形容器的安全性作些初步的分析,以利于今后球形容器的建造和使用。 In recent years due to the petrochemical industry, city gas and other industries to large-scale development, the use of spherical containers are also increasing. The practice of construction and use over the years (such as some problems found in canning inspection) reflects some of the problems existing in the selection and construction of spherical containers at present, and also creates some illusions. Therefore it is necessary to make some preliminary analysis of the safety of the spherical container in order to facilitate the construction and use of the spherical container in the future.
