11、ervisor should be informed to come to witness by giving valves pressure test notice.閥門的強度和密封性試驗應用潔凈水進行。對于奧氏體不銹鋼閥門試壓，水中氯離子含量不得 超過50PpM （試壓用水試壓前必須檢測，并具有合格報告，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

12、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第5頁共9頁when eligibility report is available)閥門試驗用的壓力表需經(jīng)計量檢測合格，并在有效期內(nèi)，其精度不低1.5級，壓力表使用時不得小于2塊，表滿刻度值應為最大被測壓力的1.5-2倍。Prior to use, the pressure gauges must be measured

13、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.閥門殼體強度試驗壓力根據(jù)到貨閥門的標牌參數(shù)確定(如到貨閥門標牌無試驗參數(shù)，應確定為公稱壓力的1.5倍)，且

14、試驗時間不小于 5分鐘，以殼體、填料無滲漏為合格。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

Seal the inlets

22、& outlets of the valves after they have been dried off. Provide distinct markings on the accepted valves and separate them from other valves.按交工要求填寫相應閥門試驗記錄。Perform the relevant valve test record as per handover requirements.安全閥應在有資質的部門進行調(diào)試，合格后，現(xiàn)場直接進行安裝。第7頁共9頁Safety valves should be tested and appro
