一份十分详细的管道静压测试流程？ 1. often a 10 cycle pressurization test is most desirable to confirm good soundness. then the measurements are taken in the last pressurization. prior pressurization cycles in a cyclic test many use holds at pressure for 10 minutes or more 这里hold是否可以理解为“保压”？（maintain a pressure )——保压，没错儿 2. if the system is not flanged or otherwise fitted to permit tying in with standard fittings, 这里tie in with 是否理解为"接合“？— —连接，结合 3. if possible the pressure test gage should be located at the centerline elevation-of the lowest pipe in this particaular system. if the test gage must be at a higher location, the test pressure must be decreased for this difference in head. head我注意了很久 但是这里不知道该做何解？—— 应该是指静压头，请注意介质装满后高低点的压力差 查看更多
