Any information is appreciated.

Your post is too broad and inspecific to provide accurate guidance. You nee dto do some research and then post on specifica questions.

First point should be to review the regulatory requiremenst wher ethe equipment operates - this will give you some guidance on requirements and frequency plus potentially some referencing documents.

In addition you may want to review API In Service Inspection Codes and or some of the guidance on the UK HSE website. This will give you some insights.

Thanks I have checked one of the API specs. Api 510 in-service piping.

Seems it is dependent on the RBI. Things like UT, X-Ray, Thermography, Pressure Testing, Visual and so on should be used to find things like fatigue cracking, corrosion and on.

Also seems to be formal courses on the matter.

Anything else?
