I am thinking of using PIR/UR as the default insulation for pipe support. This insulation will find application on cold duty of a onshore terminal. Has anyone encountered any problems in the past/present with this material? Also, I am advice to look up the flame spread index (surface burning...

looks like galvanic corrosion or some form of preferential corrosion to me.

Fatigue of piping of course...:)

Thanks for your input..:) Just one more question. How would noise/vibration affect the integrity of the insulation?I can only assume this would loosen the hold of the insulation to the substrate.

A robust fabric maintenance programme is neccessary to mitigate corrosion under insulation (CUI) or corrosion under fireproofing of assests. This phase comes after the plant has been fired up. For FEED phase, what are the parameters should I incorporate when designing for the prevent of...

(Metengr) Thanks for your input. (Cloa) I think it is the same for consultants but at higher level.

Spot on Walterke...I am indeed looking for a job. Someone asked me once 'Do you have any site experience?'. It is a too general question (bias I think). So I was wondering how would he or she answer this particular question.

I was referring to materials and corrosion engineers. Does site experience means plannning, overhaul etxc etc

Hey guys How important is site experience and what does it really mean? i.e. what type of key responsibilities are they referring to?

Edstainless Thanks for your information There will be some methanol and demin water. The proposed material of construction is either 304 or 316. These materials will seeing temperature as high as 300C but for no more than 72hrs (regeneratio process. Where can I find corrosion rate...

Hi guys I am looking for information on SCC by caesium hydroxide at crica 300C. Does anyone know material(s) suitable for this type application?

Could it be the weld laps from friction welding that has been left in situ? Mind you, if they aren't removed, they can act as stress concentrator.

Chromium carbides?

If you intend to measure the carburized layer, perhaps using a Knoop indenter for microhardness testing(ASTM D1474 standard)would be more useful.

TDear all, Thank you so much for your advice and support.

SJones:I am working on my chartership with IOM3 as we speak. How do I get to your level of work experience? Mrfailure: I can see your point with regards to networking. My department is rather close-minded and tight i.e. they gave me the death stare when I requested for an upgrade for our...

Thank you for your insight. I am often in the lab conducting test and a solo role plus rarely get out from the office. I am trying to make the transition from lab to field work as I feel I will learn more from field work. Great to hear you had good mentors to have open discussions.

Life cycle cost is ultimately the contributory factory that ties in with the inspection/maintenance periodicity. How long did the previous sprayer dryer last before a replacement is needed? I don't know this would help much but it talks about carbon capture plants and carbon dioxide corrosion...

I have heard a case where an industrial boiler water wall tubes failed by HTHA but the primarily cause was directly due to on-loading corrosion. This happened during winter and the flow was below its recommended limit.
