I don't think I stated anything that says lack of experts in the field of cryogenics. I even reiterated in my post "...not due to lack of experts, but by companies trying to save money..." and this was brought about by the previous statement from a that "Everbody need not be a expert of all things and mainly cryogenics..." You are right, they need to hire experts.""Just don't expect it to be given away"
"...vast availability of information in the internet..." I got 49,800 hits on google search for cryogenic piping. That's a lot to sift through. No question, Paul's mention of the the Piping Handbook is a good place to start. And as I said companies dealing with cryogenics are good sources of info due to the Standard Procedures.

As far as the other issues are concerned...I thought I was posing rhetoric questions. But anyway, IMO, as an analogy, the preacher has more responsibility to God what he or she preaches to his or her constituents.
And you're right about this "There's a lot of casting about on this list by people who don't know what they're doing or who are looking for free engineering. It's not the job of the more experienced subscribers to play nursemaid." Especially the free engineering stuff.

Have a good weekend.
