DCS/SIS 的机柜、操作台、仪表、 仪器等设备的开箱检验工作应在中国海关商检人员、 EP 承包商、采购部、监理承包商及施工承包商等人员到场的情况下共同开箱。 Opening and checking instruments and apparatus of DCS/SIS such as the machine desks,operation desks,instruments and apparatus of DCS/SIS should be done when China Custom checker,EP contractor,procurement department,supervision contractor and construction contractor have been to the location. 开箱检验工作中发现的遗漏、差错、缺损等情况，根据赛科要求应由采购部交 EP 承包商及时处理解决。 If the omit,error,short and damage be found when opening and checking, procurement department should hand it on EP contractor in time according to SECCO requirements. 说明书等随机资料至少必须提供一份复印件给施工 承包商。 At least a copy data such as directions should be handed on the construction contractor. 节流装置在安装应前将节流元件取出进行加工尺寸检查，并做好检查记录。 Throttle elements should be taken out and check their measurements before installing the equipment,note it carefully at the same time. （ 2）材料配件入库验收要求 the requirements of material fittings housing 检查材质、型号、数量、质量是否符合赛科、设计要求。 Check if the material,type,quality and quatity ply with the requirements of SECCO and designing. 检查是否有质保书，核对质保书批号与所供货材料批号是否一致，并将质保书收起由专人妥善保管。 Check the qualityensuring book and if the types are corresponding in qualityensuring book and materias provided,and safekeep the qualityensuring book by special person. 材料代用要赛科公司、设计或监理书面 认可。 Materials replacing should be accepted in writing by SECCO,designer and supervisor. 在仓库保管期间，各类材料应有明显型号标志，并应分类堆放。 In the course of storage,all kinds of materials shall be marked obviously and piled up according to species. （ 3）对验收不合格者一律不准入库，并应及时通知赛科、 EP 承 包商、监理，待其提供处理意见后方可处理，不得用于工程。 The unqualified shall not be housed. Inform SECCO,EP contractor, supervisor on time and shall not been dealed until they provided disposal shall not be used in project. 六、焊接施工规定 welding Construction Rules 仪表焊接施工前，电焊 作业人员必须提供相应钢种且在有效期内的焊工合格证书。 The welders must provide the corresponding steel kinds and the certification in valid. 焊工焊接作业之前必须清楚所焊工件的具体材料，按焊接责任工程师所编《 90 万吨 /年乙烯装置焊材选用表》选用焊丝、焊条。 The welders must know the concrete materials clearly before welding and choose welding rod and welding silk according to the Table of Selecting Welding Materials of 900KTY Ethylene Plant which be statemented by the charging engineer. 焊条及焊丝按乙烯项目部制定程序领取。 Welding rod and welding silk should be pulled down by the procedure made by the Ethylene Department. 点固焊与正式焊的焊接工艺，选用焊材应一致，焊接前必须将焊口内的油漆、铁锈、氧化物等清除干净。 The process of dot fixed welding and formal welding should select the same painting,rust,oxid in the welding jaws should be cleaned before welding. 阀门焊接时，阀门必须处于开启状态。 The valves must be open when welding. 耐热合金钢等特殊导压管焊接作业，应按焊接责任师下发的工艺卡施工。 The special guiding pressure pipe welding works such as bearing hot alloy steel should be constructed according to the process card sent by the welding charger. 为保证焊接质量，不锈钢导压管及伴热管焊接采用氩弧焊焊接工艺。 For ensuring the welding quality,stainless guiding pressure pipe and withhot pipe welding should adopt the argon arc welding process. 仪表立柱及现场支吊架必须满焊，及时清理焊渣及药皮。 The instrument standing poles and supports on field must be welded fully,the sediments and dug peel should be cleaned on time. 工艺设备及管道表面严禁焊接支架或进行引弧。 The welding supporting and guiding arc shall not be done on the surface of process equipments and pipes. 焊接完成后，应及时对焊口进行防腐处理。 When welding finished,the timely anticorrosion dealing on the welding jaws. 七、 仪表施工技术规定 Technical Stipulation for Instrument Co。
