LN2 cryogenic vacuum jacket piping

[hjulien]

Hi every body,

I'm starting in the Liquified Nitrogen vacuum jacket piping industry. Can you suggest me good documentation as a start or good training offered by recognized organization in North America?

Thanks in advance,

hjulien

Hi hjulien,
Designing cryogenic systems or even just portions of such systems, such as vacuum jacketed piping, requires a background in a number of different but related fields. You won’t get everything you need to know from one course.

For VJ piping I’d suggest first taking the ASME B31.3 piping code course since all VJ piping should comply with it. This covers such things as pressure design, materials of construction, flexibility due to thermal contraction, etc… You should take this course directly from ASME:

http://catalog.asme.org/Education/ShortCourse/B313_Process_Piping.cfm

A second course would be a general cryogenics course. Can’t remember what I’ve taken now, but looking around the web, this one looks pretty good:

You should also be very familiar with vacuum systems so I’d suggest a vacuum course such as this one, although I'm not recommending this particular course:

People you work with should also be able to direct you to what courses they would suggest and have taken, so ask around.

In addition to formal training, I think the best way of learning anything is to get a mentor at your place of employment that can help with your professional development. Learning from someone on the job is probably the best way of learning anything in engineering. Consider who you can work with carefully, the right person should be able to give you an education that is far and away better than anything you could recieve formally.

Sir,

Like you, I hit the cryogenic field without formal training.

You need good vendor / manufacturer's rep. Someone that the manufacturer endorses. The Cryogenic Societies have links to VIP manufacturers.

You are not really going to design the piping. That can be procured via the manufacturer and his agent.

What you need to do is determine the basic routing and procurement requirements you need.

The advice to pursue B31.3 is good, but there is very little training available to design cryogenic piping.

Remembe that there are 2 basic types of VIP, passive vacuum and active (pump).
