For pipeline water pressure, do you conduct pressure testing before flushing or after flushing?
Thread Content
A hydrostatic test is being carried out now. According to the specifications and our own understanding, it involves pressurizing the pipes with water; first, the pipes are flushed with water to prevent impurities from clogging instruments, safety valves, etc., thereby avoiding unnecessary problems or inaccurate readings. However, the workers on site first carried out a pressure test and then released water; in reality, no flushing was done, and it was merely the water from the pressure test that was discharged. I don’t know how you guys do it on site. . .
Generally, the pipes are rinsed under water pressure
If there are no special requirements, we generally do not rinse it:(
Don’t you deal with the rust, slag, dust, and stuff in those pipes?
Sure enough, it’s the same; we’ve washed them before, and there were rags and mineral water bottles as well.
Aren’t you afraid of clogging the pressure gauge and temperature recorder?
The pressure gauge is installed after flushing; the instrument room does not apply pressure, as there is a risk of damaging it
Pressure gauge for pressure testing. . . :L
It’s better to rinse first if conditions permit; however, in most cases, a thorough cleaning of the system is carried out. If conditions are limited, rinsing first is of course also fine
