清洁检验规程.doc

清洁&检验规程（Rev. B）一、 目的This is the guideline for fabrication, cleaning, inspection and packing of equipments，piping and instruments to avoid any possible contamination from fabrication to installation of equipments，that is，it is to secure cleaning condition of contact parts with process liquid in the end. The control factors are oiliness，rust，organic matters and other matters which can be influenced to degree of purity，the cleaning should not give any influence to original characteristic of equipments which are cleaned. 这是设备、管道及仪表的制造、清洗、检测及包装操作规程，以防止设备从制造到安装污染；也就是说，最终工艺的接触部件保证是清洁状态。控制因素为油质、铁锈、有机物质和影响纯度的其他物质，所进行的清洁方式不对所清洗设备的原来特性造成影响。二、 应用范围This guideline is applied to all equipments which are contacted with process fluid. 本准则适用于与工艺相关的所有设备。三、 清洁规程This guideline rules all cleaning procedures which will be performed before all equipments are delivered after fabrication. Cleaning plan has to be examined and applied from purchasing equipments, design and production stage. (See attached Flow Chart)此规程规定所有设备制造完成之后、交货之前，进行所有清洁程序。检查并应用所购设备、设计及生产阶段的清洁规划（见附件流程图）。1、 Surface treatment表面处理For effective cleaning, surface treatment (CS : Buffing-#200 or sand or shot blasting / SS : Buffing-#200or EP)should be preceded. 为有效的清洁，提前进行表面处理(CS: 抛光- # 200 或砂或抛丸除锈/ SS:抛光- # 200 moisture density : due point -30 below / O2 density : 0.5volume% below), it is able to perform particle counting if necessary.通过检验的设备最后应进行IPA清洁，然后用氮气吹扫（5N用0.1m过滤器）。1.5kg/cm2氮气吹扫5次，但是如果设计压力低于2kg/cm2，在操作压力下吹扫5次。（干燥条件湿度：露点-30以下/：O2密度0.5volume%以下），根据需要使用粒子计数方法。四、密封包装1、 Sealing and packing should be done under clean condition.在清洁状态下，完成密封包装。2、 Sealing pressure should be kept at 0.3-0.5kg/cm2 for 3 months at least and it should be checked at any time mounting pressure gauge.密封压力应保持为0.3-0.5kg/cm2至少三个月，应安装压力表以便随时进行检查。3、 After sealing, all nozzle of the equipments (small sized equipments are capped all over) should be capped with clean vinyl or PE sheet, replace inside air with N2.密封后，所有设备的管口（小型设备也要全部密封口）应该用干净的乙烯基（塑料）或PE板封口，并用空气及N2进行置换。4、 In case of pipe, for sealing, do sealing with N2 after installing separate clamp at the end of pipe and a valve at one side of that. In case of fittings and valves ,it should be sealed with N2 putting into plastic bag (vinyl bag) after end capping. And, in case of CS pipe and fitting, to avoid rust, its outside should be painted (with Epoxy Primer 1Coat) after complete sealing with N2. To distinguish piping materials,End Cap Color should be applied as follows. SUS 304(white), SUS316(yellow), Incloy800H(red)，carbon steel (black), Alloy(blue)如果是管道密封，在管道末端及阀门一边分别固定后用氮气进行密封。如果是配件及阀门，用氮气密封后放置于塑料袋中（乙烯基袋）。如果是碳钢管及配件，氮气密封后在外部进行喷漆（用环氧底漆）。为了区分管道材料，封盖所采用颜色如下：SUS 304(白色)、SUS 316(黄色)、Incloy 800H(红色)、碳钢(黑色)、合金(蓝色)5、 Packing包装5-1. Do not use materials which tear easily or easy to brake. 勿使用易磨损材料。5-2. To distinguish inside packing materials, adhere Tag No.respectively.为了区分内部包装材料，分别贴标签编号。5-3. Each equipments should be packed as wooden packing respectively and equipments Tag no. should be distinguished easily at the outside.用木制包装材料分别包装每一个设备，并在外部贴上标签以易于区分。 五、保存1. In case of the equipments whith passed inspection, never discharge N2 without approval from the engineer in charge before installation.若设备检查合格，在安装前未经工程师批准，决不能排放氮气。2. In case that corrosion occurs or foreign materials entered as N2 concentration goes down in the process of installation, to keep inside clean condition surely, line filter (0.01um) should be installed and N2 (5N) should be filled up.若安装过程中由于N2浓度降低，发生腐蚀或产生杂质，为了确保清洁状态，应安装管道过滤器(0.01um)并充满N2（5N）。六、清洁级别1. “A” class : degreasing + Acid cleaning item (all of SS/Alloy/ Si3N4, some of CS)“A”级：除污+酸洗项（不锈钢/铝合金/Si3N4，CS）2. “B” class : degreasing item (just for carbon steel)“B”类：除污项（仅限碳钢）In case of SS/Alloy/ Si3N4 steel, acid cleaning should be done for in/outside although its cleaning class is class is classified to class “B”.对不锈钢/合金钢/Si3N4，尽管它的清洁类归为“B”类，应采取内/外酸洗。七、清洁检查1. Bright light inspection : There should be no any foreign materials on the surface cleaned externally when it is inspected under bright light.强光检验：强光下检查，清洁的表面上不应存在任何杂质。2. Clean wiper inspection : The surface of equipments cleaned should be clean without any oily materials, particle and dust etc. when it is rubbed with clean wiper.无尘布检验：用无尘布擦拭时，干净的设备表面不应该存在任何油性杂质、颗粒及灰尘等。3. UV light inspection : The inspector has to check that oily materials, particle and dust are completely removed, that is ,there should be no oily materials particle and dust and dust when UV light shines cleaning parts.UV光检验：检查员检查油物质、颗粒和灰尘是否清除彻底, 也就是说, 不应该存在任何油类物质粒子和灰尘。八、备注1. In accordance with this guideline, vendor should submit (1) Cleaning procedure, (2) Inspection sheet togther with vendor print considering characteristics of equipments in full and should get approval from HKS.按照此规程, 供应商应该提供(1)清洁程序、(2)检查表以及设备特性, 应由HKS批准。2. Vendor should consider cleaning procedure from design and fabrication stage, sanding and brushing of raw materials should be performed for smooth cleaning which will be performed prior to fabrication.供应商应考虑从设计到制造阶段的清洁规程，在制造之前要用砂纸打磨, 并刷干净。3. All cleaning works should be performed to mainly concentrate upon welding parts, before warehousing of the equipments.储存所有设备之前，进行全面清洁工作主要是为了焊接。4. In case of all nozzles except blinded nozzle on specification sheet, it should be connected with temporary blind flanges plated with plastic or CS+Zn which is inspected with acid. In case of gasket, Teflon gaskets (all sides) which are inspected with IPA should be used.对于数据表中所有管口（盲管口除外），应临时连接酸检过的塑料或CS+Zn盲法兰。对于垫片，使用IPA检查过的聚四氟乙烯垫片（所有边）。5. As for gauge and valve for N2 purge, 304SS should be used as their materials ,they should be inspected with acid before mounting.对于N2吹扫仪表及阀门，它们的材质为304SS，安装之前进行酸检。6. Never mark with marker or paint on the equipments in the process of fabrication.制作过程中，绝不在设备上做标记或喷漆。7. Cleaning inspection should be performed from acid inspection to packing per each processes respectively, the sign for confirmation should be done per each process as well.分别从酸性检查到包装的每一步程序进行清洁检查，并对每一步进行签字确认。8. When acid cleaning of vessel and tower, to prevent any accident or danger, ventilation system should be installed so that fresh air can be flowed into inside and discharged.(air supply fan,exhausting fan and heap filter should be installed and O2 analyzer should be equipped,too.) Inside temp.of vessel and tower should be kept at 20C and the 2nd pollution by sweat should be prevented酸洗容器和塔时，为防止任何事故或危险，应安装通风系统以使新鲜空气进入并换气。(应安装空气输送风机、排风扇和过滤器，并配备氧气分析仪。) 容器和塔内温度应保持20，应避免汗水导致二次污染。9. In case of the chemicals for acid cleaning, pre-mixed chemicals for acid inspection only should be used, but its components should be approved in advance. The chemicals for acid cleaning should not include Boron, Oily Carbon (C4C10) and Phosphorus, and should be handled with care especially. Also MSDS to the chemicals for acid inspection should be secured and known in full, the operators should be fully trained.对于酸洗的化学品，仅使用预先混合的酸检化学品，但其成分应预先得到批准。酸洗的化学品不应包括硼，油碳（C4C10）及磷，并应特别处理。此外，物料数据表中的酸检化学品应充分了解，并对操作人员进行全面培训。10. When acid cleaning is performed, the operators should surely
