How would you prioritize inspection intervals across hundreds of tanks in a petrochemical complex?

In one of our material handling unit, we have been facing issues of repetitive piping blockage. We believe that other than the heat tracing (installed to keep the material in melted form) effectiveness, smaller line size is also playing a role. However, would this be possible to just change the line ...

Management of operating & maintenance procedures is of the key process safety management indicator, just to start with.
Typically, all procedures are required to be reviewed, and updated every 3 years, controlled by ISO.

Even though 25-22-2 has good carbamate resistance, it is still vulnerable to localized pitting when chlorides contaminate the system.
Typical chloride sources:
Cooling water leakage
Steam condensate contamination
Hydrotest water
Improper flushing water
Contaminated passivation chemicals

Reynolds number is the key here;
Once you calculate Re:
Re < 100 Laminar (very rare in shell side unless viscous fluid)
100 < Re < 1000 Transition
Re > 1000–2000 Turbulent crossflow
What is your intent?
Why are you worried about turbulence?

Temporary repairs are in numbers before we approach any shutdown window to apply permanent nature of repairs. The management is important to address all those once that window is available. Currently at our site, maintenance teams are responsible to have them enlisted and make them part of the ...

The interesting part here is that IEC 61511 doesn’t say to actually create an SIS Master Register.
What is does say is to track all SIFs, maintain lifecycle data, control changes, monitor performance, manage bypasses. And that all one cannot do without having a register in place.

What are the factors that a U-tube bundle is selected over fixed tube one?
I know about accommodating expansion during high temperature applications, bundle is removable, what else?

Definitely it is a case of Tier-3 API 754 KPI.
If there has been a demand for cauum relief to activate, it is required to be registered.

This is the same observation we had at our site as well where we see some of the equipment with cleats provided to their skirt supports however with no fireproofing. I am not sure whether our HSE has already observed and evaluated that or not but all what I could say is that this is true with ...
