二硫化碳

• Cleanup corrosive substance in pipe such as internal water , clean oil , methane hydrate , ferric oxide , carbide dust , carbon bisulfide , hydrosulphurice acide , etc . ; reduce corrosion damages to inner wall of pipeline caused by corrosive substance ; clarify pipe route again ; inspect pipe deformation ; check perfectness ratio of valves along pipe ; decrease working backpressure
  清除管线内部积水、轻质油、甲烷水合物、氧化铁、碳化物粉尘、二硫化碳、氢硫酸等腐蚀性物质；降低腐蚀性物质对管道内壁的腐蚀损伤；重新明确管线走向；检测管线变形；检查沿线阀门完好率；减小工作回压。
