管道的试压及冲洗 Pressure test to pipe and flushing
管道采用自来水进行试压，冷凝水管采用自来水进行灌水试验。 Pipe pressure test shall use tap water，condensate pipe used tap water for watering test.试压、冲洗前一周，根据现场情况，编制试压、冲洗作业指导书，明确水源，排放点等关键环节。 Establish guide books for pressure test and washover operation, determine the key links such as water source and discharge point one week before washover.

管道水压试验 Water pressure test of pipe

华译网北京翻译公司翻译过大量有关管道水压试验的文件资料,Beijing Chinese Translation Service Company has translated many technical documents about Water pressure test of pipe
A、A、
管道系统在试压前，按设计施工图进行核对。 Inspection according to the construction drawing before pressure test.对支架是否牢固，管线是否为封闭系统等有可能对试压造成影响的环节进行检查。 Make inspection to links such as whether the bracket is firm，pipeline is the closed system or not.
B、B、
安装试压临时管线、试压仪表及设备。 Install the temporary pipeline, instruments and equipments for pressure test.在系统最高点设置放空装置，最低点设置排污装置，对不能参与试压的设备与阀件，加以隔离。 Set emptying device on the peak point of system and blowdown apparatus on the minimum point, the equipments and valves which are not needed for pressure test shall be isolated.
C、C.
系统注水过程中组织人员认真检查，对发现的问题及时处理。 During the course of system water flooding, workers shall inspect carefully, discover problems and immediate attention.
D、D、
系统试压时，压力应缓慢上升，如发现问题，立即泄压，不得带压修理。 Slow rise pressure during pressure test, if there was any problem, pressure relief immediately and then make repair.
E、E.
系统工作压力为：B区0.8Mpa,其余均为0.6Mpa。 Working pressure of the system: area B is 0.8Mpa, the others is 0.6Mpa.当压力达到强度试验压力时（工作压力的1.25倍），稳压10分钟，作全面检查。 If the pressure reaches up to the strength test pressure (1.25 times of the working pressure), pressure stabilization for 10 minutes and make complete inspection.以管线不变形，降压不大于0.02mpa为合格。 The pipeline is acceptable if the pipeline keep its shape and the pressure reduction is no more than 0.02Mpa.压力降至工作压力作严密性试验，稳压30分钟，以无压降、无渗漏为合格。 Drop of pressure to the working pressure and make proof test, pressure stabilization for 30 minutes, non pressure loss and no leakage is acceptable.
F、F、
管道系统试压合格后，及时排除管内积水，拆除盲板、堵头等，按施工图恢复系统，并及时填写《管道系统试压记录》。 If the pipe system is acceptable, drained the seeper in pipe and dismantle stop plate and bulkhead in time, recovery system according to the construction drawing and fill in "The pressure test record of pipe system".
