This scheme is for the anti-corrosive painting engineering of the pipeline of Bayer Isocyanate & PET Project MDI Train-Tank Farm(V911,V912,V913).2.0 工程概况GENERAL该项目罐防腐为3号系统(system 3),分底漆,中间漆和面漆三层涂装,不锈钢(保温)罐为4号系统(system 4),分环氧清漆、面漆三层涂装,涂层总干膜厚度不低于200微米。

This project, Bayer Isocyanate & PET Project MDI Train-Tank Farm has nineteen carbon steel tanks and six stainless steel tanks to beantisepsis. The soleplates of carbon steel should be carried to the anti-corrosive place to do blast cleaning and painting (the components that can’t be derusted by the abrator should be derusted by blasting copper ore). Carry it to the construction scene after primary coat finished. Then, barrior paint and finish coat shall be covered when pressure has been tested and qualified(carbon steel tanks below 120℃). Below 120℃, the carbon steel tanks with derusting rating Sa2.5 is System 3. It should be covered with three coats including primary coat, barrior paint and finish coat. The epoxy zinc-rich primer should be thick 80 polyurethane finish coat60 thick. The dry coating should be 240 Stainless steel tanks below 120℃ is System 4. They should be covered with three coats. They are epoxy varnish, polyurethane finish coat.3.0 编制依据PREFERENCES3.1拜耳规定CSA0056-Corrosion ProtectionBayer Regulation CSA0056-Corrosion Protection3.2拜耳规定BISS-ES-50-001Bayer Regulation BISS-ES-50-0013.3 工程设计图纸Figures of the Project Design3.4 DIN EN ISO129443.5“油漆工程规定”(中国石化集团南京设计院)Regulations of the PaintingProjects(Sinopec Nanjing Design Institute)4.0 施工和检验程序Application of the Construction and Test4.2贮罐施工检验程序Application of Testing Tanks Construction4.2.1预制厂施工程序Application of the Prefabricate Plant施工前的准备贮罐底板和基础涂装前表面处理与检查底漆喷涂底漆检查与验收中间漆喷涂与验收面漆喷涂检查验收Preparation before application, removing the identifications →disposing and testing the surface before coating →checking and acceptance of primary coat→checking and acceptance of barrior paint→painting finish coat →checking and affirmance4.2.2现场施工程序Application of local construction施工前的准备贮罐试验合格贮罐表面处理与检查底漆喷涂底漆检查与验收中间漆喷涂与验收面漆喷涂检查验收Preparation before application→qualifying of testing the tanks→the brushing and examination of tanks surfaces →painting finish coat →checking and the painting of finish coat →checking and acceptance5.0施工准备Preparation for Construction5.1施工准备Preparing the construction5.1.1施工现场道路平整、畅通。

The road in the construction area should be leveledup and unimpeded.5.1.2施工现场水电具备使用条件。

The water and electricity at the scene ofconstruction should have the qualification to be used.5.1.3适当的施工机具及检测设备齐全,材料堆放到现场。

Appropriate machinesand equipments should be sufficient.The materials should be placed at thescene of the construction.5.1.4施工操作人员技术培训合格,持有上岗证。

The staff for construction shouldbe trained to qualify the skill required and get the qualification certificate.5.1.5熟悉甲方关于施工的技术要求资料并向所有施工人员进行技术交底。

Knowing the technical requirements of the construction well, and tell them tothe staff concerned.5.1.6在现场进行铜矿砂除锈时应做好隔离措施,在贮罐周围搭设脚手架然后在脚手架外侧用帆布围挡,把整个要喷砂的贮罐围起来,控制空气、环境的污染。

Isolation measures are needed in derusting with copper ores on theconstruction scene. Scaffoldings should be erected around the tanks, then theyare to be defended by canvas outside. Surrounding the tanks to be blast copperores is aimed to avoid personal injuries or pollution.5.2材料准备Material Preparation5.2.1开工前应做好详细的用量计划,逐步落实、运抵库房、保证施工供应和施工进度。

The materials to be used should be planned detailed. Then buy all of the materials needed and carry them to the storeroom to ensure the needs andprocess of the construction.5.2. 2油漆使用时应严格按照材料说明书的数据进行检测、控制。

The paint to beused should be examined and controlled strictly according to the data in the specification about the material.5.2. 3材料验收Checking materialsa、油漆、固化剂和稀释剂三种配套材料应由同一生产厂家供应。

Paint,reinforced agents and diluent agents should be provided by the same manufacturer.b、涂料应商品有厂名、生产日期、存储期限等内容完整的标志,产品使用说明书及质量合格证,否则应拒收。
