The Pressure test platform is mainly made of shaped steel (HW150*150*7*10及HW200*200*8*12) and connected by welding. Reinforcing bracing is optional if necessary.6.2 制作平台尺寸如下图所示。 Dimensions of the platform is shown in the below sketch.6.2.1平台底板俯视图 Plan of platform bottom plate6.2.2 平台立面图 Elevation of platform6.2.3 试压泵进水示意图 Sketch map of pressure test pumping taking water七、阀门试压 Valves pressure test7.1阀门入库前必须将阀门质量证明文件报验，合格后 ，才能入库登记。阀门试压前，应出阀门试压检查通知单通知监理人员到场见证。Valves certificates must be reviewed and approved before being registered into warehouse.Prior to the pressure test, representatives from supervisor should be informed to come to witness by giving valves pressure test notice. 7.2阀门的强度和密封性试验应用洁净水进行。对于奥氏体不锈钢阀门试压，水中氯离子含量不得超过50PPM（试压用水试压前必须检测，并具有合格报告，才能使用）。 The strength and tightness test should be performed with clean water. For pressure test for valves made of Austenitic stainless steel, the concentration of chlorine ion in the water must not be higher than 50PPM (Check the water before the pressure test and use the water only when eligibility report is available)7.3阀门试验用的压力表需经计量检测合格，并在有效期内，其精度不低1.5级， 压力表使用时不得小于2块，表满刻度值应为最大被测压力的1.5-2倍。 Prior to use, the pressure gauges must be measured and checked as acceptable, within the period of validity, and the precision level not under 1.5. In the test, no less than 2 pressure gauges must be used and the full range of measurement scale should be 1.5-2 times of the maximum pressure tested. 7.4阀门壳体强度试验压力根据到货阀门的标牌参数确定(如到货阀门标牌无试验参数，应确定为公称压力的1.5倍)，且试验时间不小于5 分钟，以壳体、填料无渗漏为合格。 The pressure value of the shell strength test should be determined as per the labeled parameters of the valves arrived ( if no such parameters are available, 1.5 times of the nominal pressure should be applied), and the testing duration should not be less than 5 minutes, and deemed as qualified if no leakage of packing or from shells happened.7.5 闸阀，截止阀强度试压合格后，需做上密封试验， After the Gate valves, check valves have been tested as acceptable, then perform the upper sealing test.-上密封性试验压力根据到货阀门的标牌参数确定(如到货阀门标牌上无试验参数，应以公称压力的1.1倍进行) The testing pressure value of upper sealing should be determined as per the labeled parameters (if no such parameters are available, 1.1 times of the nominal pressure should be applied).-上密封试验的步骤为：封闭阀门进出口，松开填料压盖，将阀门打开并使上密封关闭，向腔内充满水，逐渐加压到试验压力，达到保压规定的时间后，无渗漏为合格。 The steps of the upper sealing test should be: seal the inlet & outlet, loosen the packing cap, fill the cavity with water, gradually increase the testing pressure until the specified pressure maintaining duration is achieved and accept as qualified if no leaking occurs. 7.6密封性试验也应根据到货阀门的标牌参数确定(如到货阀门标牌上无试验参数，应以公称压力进行试验) 引入介质及施加压力的方向应符合下列规定The tightness test should also use the specified tagged parameters (if no such parameters are available, f the nominal pressure should be applied). The media introduced and the direction of pressure applied should follow the below regulations:-规定了介质流向的阀门，如截止阀等应按介质流通方向进水试压。 Valves with designated media flow direction. For example, hydro pressure test should be applied to check valves etc. as per the media flow direction respectively. -没有规定了介质流向的阀门，如闸阀、球阀、旋塞阀，蝶阀等应分别从两端引入介质、进水试压。 For pressure test of valves without specified media flow direction, for example, gate valves, ball valve, plug valve, butterfly valve etc. media or water should introduced from both ends of the valve. -止回阀应沿阀门关闭的方向进水试压。 Check valve should be pressure tested with water flowing along its closing direction.-密封性试验以阀芯或阀瓣密封面不漏为合格。Tightness test that witness no leakage from valve trim or the sealing face of the valve disc should be deemed as accepted. 7.7 试验保压时间 pressure-keeping duration公称直径DN保压时间（Min）Pressure-keeping duration上密封试验Upper seal test密封试验Sealing test强度试验Strength test504565-15045200-30045350457.8 对试验不合格的阀门,需更换。Replace those valves which failed the test.7.9试验合格的阀门应及时排尽内部积水，吹干后封闭阀门出入口，试验合格的阀门应有明显标记，不得与其它阀门相混。 Water trapped in the valves accepted should be drained immediately. Seal the inlets & outlets of the valves after they have been dried off. Provide distinct markings on the accepted valves and separate them from other valves.7.10 按交工要求填写相应阀门试验记录。 Perform the relevant valve test record as per handover requirements. 7.11 安全阀应在有资质的部门进行调试，合格后，现场直接进行安装。 Safety valves should be tested and approved by authorized unit and installed on site without further test procedures.八、人员、材料、设备清单List of personnel, materials, and equipment8.1 人员计划 Manpower plan工种Discipline人数Number单位Unit备注Remark管工Pipe layer3人Man焊工Welder1人Man8.2材料名称Name规格型号Specification & Model单位Unit数量Qty.试压平台Pressure test platform 个Pcs1不锈钢针型阀 Stainless steel needle-type valveDN10 个Pcs4橡胶板 Rubber plate=3 m230输水胶管 Plastic water feeding pipe50 米M100无缝不锈钢管 Seamless stainless steel DN10 米M15压力表Pressure gauge 0.6 Mpa块Pcs4压力表Pressure gauge1.0 Mpa块Pcs6压力表Pressure gauge1.6 Mpa块Pcs8压力表Pressure gauge2.5 Mpa块Pcs8压力
