储罐水压试验方法

water on the tank roof for inspection, and do open the tank roof hole immediately after the test, so as to contact the atmosphere and recover to normal pressure.Рa)罐顶无异常变形The tank roof is free of abnormality and deformation. Рb)未发现焊缝渗漏为合格It is acceptable if no leakage of welded joints is found. Р固定顶的稳定性试验stability test for the fixed roof Р充水到设计液位时,用放水方法进行试验,缓慢降压,达到试验负压时,观察罐顶,试验后应立即将孔开启,与大气相通,恢复到常压。When the water is filled to the design level, conduct the test by water draining method, depressurize it slowly, when it is up to the test negative pressure, do open the hole immediately after the test, so as to contact the atmosphere and recover to normal pressure.Р罐顶无异常变形The tank roof is free of abnormality and deformation. Р 5)当考虑水的重复利用,第一台罐水压试验完毕后,缓慢打开阀3,将水直接排到第二台罐里,待两罐水位平衡后,关闭阀2,然后利用消防带进行上水;
