1 问题的提出化工某厂一台400M~3氮气球罐系1976年由某化工机械厂制造安装的球形储罐,同年11月投入使用。由于是“十年动乱”期间制造的,该球罐存在许多问题:图纸及竣工资料所剩无几,无现场安装及运行检修记录,罐体外观质量很差,存在较严重的超标缺陷(如错边、棱角),内在质量又无法确定,因此该厂在使用了十年之后于1986年停用。1990年该厂根据生产需要希望能重新启用该球罐,委托朝阳区锅检所对其进行全面检验。具有严重超标缺陷的球罐能否重新使用?对严重超标缺陷如何进行处理?这就是本文所讨论的问题。2 球罐主要技术参数(图样设计参数)
A question put forward Chemical plant a 400M ~ 3 nitrogen balloon tank manufactured by a chemical plant in 1976 installed spherical tank, put into use in November the same year. Due to being manufactured during the “Ten Year’s Upheaval,” there are many problems with this tank: there are not many drawings and completion data available, no records of on-site installation and operation and overhaul, poor appearance of the tank, and serious serious defects Such as the wrong edge, edges and corners), the inherent quality can not be determined, so the plant was discontinued in 1986 after ten years of use. In 1990, the plant hoped to re-activate the tank according to the production needs and commissioned Chaoyang District Pan Inspection Office to conduct a full inspection of the tank. Is it possible to re-use the spherical tank with serious over-standard defects? How to deal with serious over-standard defects? This is the issue discussed in this article. 2 ball tank main technical parameters (design parameters)
