I was just thinking if there should be some sort of a maintenance plan or schedule to access the condition of regularly used threaded joints?
Has there been any guidelines within some standards asking to check for those?
What sort of maintenance best practices may be applied here that some ...

To maintain any abnormal conditions like operating beyond safe operating limits, what kind of controls are required to be exercised?
Like unable to maintain dosing of corrosion inhibitor as per agreed flow listed in safe operating limits register?

Correct, I agree with you.
This is not a true representation of Technical Safety.

In my opinion, you should be considering a change management process if there is a spade in place on the system and the system is required to be taken in process.

What have been the major changes in API 754 4th Edition, 2026 when compared to 3rd one?

Asked Gemini to generate me an infographic on Technical Safety.
Result is as attached.

Monitoring is important to adjust chemical feed rates dynamically.
Use of Online Oxygen Analyzers placed immediately downstream of the deaerator and at the economizer inlet to provide real-time ppb measurements. Target levels are typically maintained below 5 to 10 ppb for high-pressure systems.
Then ...

Yes that is correct. As per API 754, now 2026 one is out as well, there is no mention of any certain parameter. Every excursion /exceedance qualifies to be reported.
But the actual issue is that someone from Operations /Process should review that excursion to be a real one.
Some of those are ...

Yes, a decrease in gas molecular weight has a severe and direct impact on centrifugal compressor surge.
Feed composition changes are one of the primary triggers for unexpected surge events in continuous operations.
Here is how the physics work: A centrifugal compressor operating at a constant ...

It is not entirely true that bubble cap trays are better across the board. In fact, modern sieve and valve trays have largely replaced older bubble cap designs in most industrial distillation columns due to their efficiency and lower cost. However, bubble cap trays do possess a few specific ...
