The recent posts about welding got me thinking about the job done in our new research building. It's got a central liquid nitrogen supply tank that feeds all of the cryogenic freezers. Well, the supply lines are just damn neat--a 3/4" inner pipe centered in a 3" outer pipe (stainless, of course) to provide insulation. I'll just say that we don't need pictures hanging up because the welding job is just pure artwork/wwwthreads_images/icons/cool.gif. I would imagine that this might be considered one of the more difficult types of welding jobs--the double layer pipe, all welds have to be perfect to contain the pressures, etc... I wish I had a tenth of the welding talent of the crew that did this job (of course, I'd need to get a real welder and ditch the car batteries/wwwthreads_images/icons/crazy.gif).
