贵刊1994年第6期刊登的《运用科学管理方法延长碱罐使用寿命》一文,作者意在“通过贮罐的最小检测壁厚减去由压力容器壁厚计算公式计算的罐体壁厚值,再与腐蚀速度相比较来推断液碱贮罐的剩余使用寿命.”笔者认为此种方法有欠妥当,考虑化工安全的重要性和理论对生产实践的重要作用,很有必要对液碱贮罐的剩余使用寿命另作分析,供设备管理人员商讨.1.由于该液碱贮罐为常压贮盛容器,且多年使用,判断其能否继续使用的最基本条件应符合化工部HG25006—91《贮罐维护检修规程》中(以下简称《检规》)5.2.1.2条之规定:
Published in 1994, No. 6, 1994, “the use of scientific management methods to extend the service life of alkali tank,” the article intended to “by the minimum tank wall thickness minus the wall thickness calculated by the pressure vessel wall thickness calculation formula , And then compared with the corrosion rate to infer the remaining life of the caustic soda tank. ”I believe that this method is not properly considered the importance of chemical safety and theory of the important role of production practice, it is necessary to liquid alkali storage The remaining life of the tank is analyzed separately for the equipment manager to discuss .1 As the liquid alkali storage tank for atmospheric storage container, and for many years to determine whether the basic conditions for its continued use should be consistent with the Ministry of Chemical Industry HG25006- 91 “Tank Maintenance Inspection” (hereinafter referred to as “inspection”) the provisions of Article 5.2.1.2:
