【Things Related to the Commissioning of Haichuan Chemical】002: Before starting up, have you checked the blind flange on the safety valve?
Thread Content
When flushing and cleaning pipelines, in order to prevent damage to safety valves and similar components, blind flanges are often installed in front of them as a means of isolation. Before starting up chemical processing operations, it is necessary to ensure that all safety accessories are in good condition and functional; therefore, these blind flanges in front of the safety valves must be removed, and the gasket bolts must be tightened properly. I wonder, fellow drivers, if you have a specific inspection procedure before driving. Please share yours
It is necessary to check all safety accessories (safety valves, pressure gauges, etc.) before driving each time
Is it just an arrangement for inspections, or is there a specific inspection system along with inspection records?
From a safety perspective, it is absolutely not allowed to use blind plates.
There are checklists, but no specific system
During equipment pressure testing, the safety valves are closed, as the test pressure is higher than the setting pressure of those valves

Check each one according to the record of blind plate installation
Inspections are not only conducted while driving; they are also carried out when there are changes in the process~~~
Ah, I was overthinking it; it’s to drive this car after all. . . . .
There are checklists available, and signatures are required for confirmation!
