摘要
上海外高桥电厂二期工程(2×900MW机组)烟囱高240m,烟囱钢内筒采用安全、优质顶升技术后,3台液压缸爬升时的差异误差小于1mm,具有极其安全、平稳的优点。通过工艺质量的严格把关,制作焊缝自动埋弧焊990条,安装焊缝手工焊90条,经100%超声波检验,按1级质量要求(Ⅱ级合格),都符合探伤标准(GB11345—89,B级)。
The height of the stack for second phase engineering of Shanghai Wai Gao Qiao Power Plant (2×900 MW generation sets) hits 240 m, after the adoption of safety, high-quality jacking technology with steel inner cylinder, the deviation error is smaller than 1 mm on climbing of 3 hydraulic cylinders .possessing the advantage of extreme safety and stability. Through strict supervision of technological quality, the manufacture of welded seams 900 pieces with automatic submerged arc welding and the installation of welded seams 90 pieces with manual welding were implemanted. On 100% supersonic testing according to the quality requirement of class I (class II is qualified), standard of defect inspection (GB11345-89, B grade)was met.
