Shanghai Daoqin Plastics Co., Ltd.

         in Tenth Construction company in project full force 组织实施 lower, 经 试 pressure small and 各区域施工队, pipeline pressure 班组 认 true 准备, in SINOPEC 一体化 project, 80 10,000 tons / year ethylene plant/unit 各区域 pipeline pressure as, from 10 month in 旬陆续开始, to 10 month lower 旬, ethylene plant/unit cold, pressure shrink, cold 区, add hydrogen and other 9 区域 pipeline pressure as comprehensive 展开.

         process pipeline pressure is tube/pipe welding quality, 阀门, method 兰, sheet/slice quality is to design standards, ensure pipeline, system safety production important and measures. ethylene 蒸汽裂 understanding, add hydrogen plant/unit 区, 共安装 process pipeline 226千米, tube/pipe welding amount 2082821吋径, and pipeline 连接 阀门30495台, system large, therefore, Tenth Construction separation formed 930 separation system pressure 包, mono pressure 包进行 pressure experiment/testing, as amount and difficult degree non large.

         is ensure pressure as 顺利进行, Tenth Construction project formed pressure as small 组. 并进行 明确 separation 工: 由一名副经理 negative pressure 组织协调;由 engineering technology long comprehensive negative pressure technology as; its in 9 区域 in 独立试 pressure 包, 由各区域安装施工队 negative pressure, system relatively large 跨区域 pipeline pressure 包 试 pressure as, 则专门 formed pipeline pressure 班, 由两名施工经理各 belt/tape 一 班组进行试 pressure. 随 各区域试 pressure as 陆续展开, from 10 month 20 day 开始, in 每 工 as day upper 组织召开 pipeline pressure as 碰头会, for issues 进行协调 solution, ensure pipeline pressure according to day, plan 进行.

         is ensure pressure as 不出现任何差错, negative 责各区域 engineering technology 人员不辞辛劳, 他们早 in 六, month 份, front 开始各 separation system pressure 包 试 pressure technology 准备工 as, made 出每 试 pressure process/workflow 图, made different type type system pressure technology solution/scheme. in pressure front, certain 一 试 pressure pipeline, 阀门安装 basic formed, engineering technology quality 人员, comprehensive good various technology 准备: for pressure as 顺序一览 table/sheet 20项 steps 规定, strip/profile 逐项检查落实.

         in plant/unit 现场看 to, engineering technology and 各安装施工队 and 班组认 true for 接尾项整改情况, 检查每一道焊口, 阀门, method 兰, sheet/plate, sheet/slice 安装, good 检查记录, to office rear, 立即完善 and provide positive 确 试 pressure various material, tube/pipe mono, process/workflow 图, mono 线图, more table/sheet, tube/pipe 线号, 阀门号, 焊工号, welding day 期, pipeline welding and 检查记录, 焊口射线 testing, testing, ratio/proportion, method 兰, sheet/plate, 临时垫 sheet/slice 拆装, pressure table/sheet combined certificate and other and other, in various material 搜集整理齐 full 报检验收 rear, again upper water pressure, notice 业主, 监理, 承包商 negative 责人, to for pressure pressure 包进行共检验收, combined rear in A grade quality control 点报验 mono upper 签字确认.

         in specific pressure pressure in, full pressure 工人历尽千辛万苦, 他们每天 in tube/pipe and frame upper upper lower, 一会儿接临时 tube/pipe 线, 一会儿 upper water pressure, or 紧螺栓, or has 无泄漏, pressure front 先拆掉阀门 and method upper sheet/slice and 螺栓, rear again upper pressure sheet/plate, pressure rear also need heavy new 恢复原样, this 一桩桩, parts parts 都由他们 hydrophilic 手 做, in this process in need 拉倒链, large 锤, to heavy large 阀门一 dry is large semi 天, especially is that large system pressure 时, has also need 昼夜不停 upper water pressure, lower 累 腰 acid 背疼. 但他们不叫苦不说累, 群策群 force, according to pipeline pressure pressure 规程操 as, according to pressure plan force 推进, pressure promote pipeline 安装 扫尾工 as, to 10 month 31 day, ethylene plant/unit already formed 106 process pipeline pressure 包 打 pressure 任务.
