一、考察的前提

锦化化工(集团)有限责任公司是特大型国有氯碱化工企业,1993 年 11 月初首次采用了苏州东山防腐仪表阀门有限公司(原苏州吴县市东山自动化仪表阀门厂)生产的衬氟塑波纹管密封调节阀山西快乐十分APP下载,用于引进 4 万吨/年离子膜烧碱上由日本提供的盐水加盐酸装置上和烧碱生产电介工艺路线中的“氯气干燥室”—氯气调节阀。以后锦化公司在扩建的 8 万吨、10 万吨、12 万吨/年离子膜烧碱的氯气和盐酸系统上陆续选用了六、七十台衬氟塑波纹管密封调节阀。由于锦化公司选用的衬氟塑波纹管密封调节阀是用于替代进口装置和氯气装置等关键部位,使用的要求既要耐腐蚀,又要密封性能好,为了保证本公司对选用该阀的可靠性,以及对我公司用于酸碱等强腐蚀和氯气介质上的调节阀选用有个定型,为此本文作者于 2002年 10 月对衬氟塑波纹管密封调节阀的生产厂家—苏州东山防腐仪表阀门有限公司针对生产工艺及产品质量的可靠性作了一次详情的考察。
