Attaching a useful document containing some good details.

Another very useful resources;

276 is good when you talk about welding due to low carbon content (<0.01%) it carries.
Carbide precipitation in grain boundaries /HAZ area would be lesser when compared to others like 625, 825 or C-22.
Excellent corrosion resistance therefore.

API 660 vs TEMA

This mapping is primarily done based upon the job function.
All those roles are required to be mapped who are responsible to ensure safe functionality of safety critical assets at site.
I confirm we have a by default mapping for all Operations, Maintenance and Technical staff except support ...

The actual issue is the coverage and allocation of extra resources.
Then not everything could be picked up when the piping circuits are all online.
mechcolor has provided some very good pointers to narrow down where exactly we might be having the issue but this all data, I hope we find that all.

Yes this is applicable in all the cases, tiror.


Yes there are changes in component /bellow OD and they are considered especially when:
Bellows are installed inside sleeves or guides.
There is insulation clearance.
Bellows are inside pressure vessel annular spaces.
External covers or shrouds are ...

It is cooling water service, so any of the recommended products by arcpro should work all fine.
Check your conditions while you make the selection.
Do you apply wrapping as well after belzona application?

The reality is that still there are sites where there is no active inspection program in place for spring supports.
That has to be addressed as a separate component from other general piping components.
Their function, issues, inspection & maintenance is required to be supported through a dedicated ...

We have a situation where welding construction flaws are getting surfaced and resulting in leaks.
What sort of quality inspection program should be put in place to address this issue?
Random inspection? What else can help us ensuring that the welds which are now in-service are all healthy?
