Shanghai Daoqin Plastics Co., Ltd.

         in Tenth Construction company in project 科学组织, control, fine tube/pipe lower, 经 安装12队10名 electrical 焊工精心施焊, to 9 month 20 day, in SINOPEC 一体化 project 80 10,000 tons / year ethylene engineering ethylene low temperature 材质 球罐按期 excellent welding formed.

        每台容积2000立方米 ethylene low temperature 球罐, heavy 290吨, 直径15.7米, thick 40 mm, 由68 block “足球瓣” type housing/shell sheet/plate for welding formed, 球罐体焊缝总 long 381米. due to it will ethylene features easy easy 爆, therefore design for 球罐安装组 for, especially is welding quality requirements non high.

        承担两台 ethylene 球罐 安装12队, is technology hard, as strong/high 球罐专业施工队, 他们常 year Tenth Construction company 南征北战, has experience and specification engineering 序, technology quality measures, one-time color formed 球罐 安装 welding 任务.

         especially is heavy in heavy welding 施工, is ensure engineering excellent, 他们采取 一 series has quality guaranteed measures: 1, use electrical 焊工操 as experience 丰富, maintain welding excellent good formed 绩, 他们进入 in 科现场 rear, full one-time property through quality 监部门举办 electrical 焊工考试并持证 upper 岗. 2, high quality standards welding material tube/pipe 理站, 并严格落实焊 strip/profile procurement, 存放, dry, 发放, recycling tube/pipe made degree, ethylene low temperature 球罐焊材 quality 保障关. 3, in 球罐安装组 for front, for has add 球罐安装, for, add temperature, welding and other as 业人员进行 严 fine true safety technology 交底, 并 每一道工序 and as upper 墙, let large 家熟记掌握操 as 规程不出差错. 4, use 帆布 整 球罐罩起 实施 full 封闭, 以此做 good anti 风, anti and other anti as. 5, welding front for need welding sheet/plate 缝进行 electrical add preheating to 150摄氏 degree above, welding process in electrical using/adopting short 距离焊缝 more welding, ensure welding temperature degree maintain in 150摄氏 degree above, 每段焊缝 in welding formed rear need maintain rear hot temperature degree 200摄氏 degree small above. 6, electrical 焊工一 separation is 二, negative strip/profile 焊缝, and 以球体 in is 基准进行 for welding, anti welding hot generate force 引起球体变化. 7, engineering technology and 质检人员 add large 巡回检查 force degree, 时时监控各项施工严格 according to welding process specification 执行.

         in strong/high has force technology quality guaranteed lower, 两台球 welding 经第三方100%探伤拍 sheet/slice 检查, one-time welding qualification rate high 达99% above, 两台球罐 high quality standards welding formed, is full 国9 month 份“ quality month ” active in-depth again light color.
