Water transport
Thread Content
Is it necessary for the diversion system to undergo a water transportation process during the startup phase of periodic major overhauls of hydrogenation units? What’s the purpose?
For the initial start-up, water transportation is necessary; after renovation, transporting it with cold oil directly poses no major issues. Water transportation is primarily used to test the performance of stationary and moving equipment, conduct leak tests, train personnel, and flush systems. These oil transports can also achieve this, reducing the commissioning period.
Yeah, I don’t think it’s necessary to use water transport; just use steam to move it along, and then transport it by oil directly
Unless there is concern about large particles such as weld slag blocking the pipeline, pay more attention to the pump inlet filter~~~
Water transport has its advantages; firstly, it can more effectively remove debris from the system. The second option is safer than oil transportation; even in the event of a leak, there’s no problem
If the device has been in operation for some time and undergoes a major overhaul, it is sufficient to displace the air with nitrogen; there is no need to use steam or water for purging! Unless the device is started up originally!
I agree; there’s no need to use water transport for major repairs, but it’s still necessary to apply heat, after all, the repairs have been carried out~~~
It is essential to use water transport for the initial startup. During major repairs, blind flanges should be installed properly to ensure that no welding slag or other debris remains inside the pipelines. Steam cleaning should be thorough, and nitrogen should be used for purging
Yeah, I think a steam clean should be enough; after using water, it will take a long time for the surface to become waterproof again
