Thanks for your input.We have since purchased a Unison 40 all elcectric and are awaiting delivery.
The Water Based lube is somthing we will be interested in looking at.We were told by unision we may be able to dry bend which will save on cleaning.

Jdarcy,
thank you ,That all was very helpful information.I am pleased to hear that you have unison benders and bend up to 4.5 inches Titanium as well.Which may be our second machine purchase requierment.
I will share this information and may have some additional questions seeing you experiance...
I didn't recall any PM options either.
that said.
Questions to Jdarcy and tohers . Can you name a water based lubricant and cleaner to try.
Also after speking with the bending shop at Boeing and doing much research we decided to go with a Unison all electric bender for about $220K.This will be...
Jdarcy, thanks again for your post but I was looking for how to PM you from this site for more of your experiance.How do I do that.Anyone?

RJ- Exergyllc is the one company that we have been speaking to about applying our bending system to their duel tube heat exchangers.Slow going, test have not occured yet.They are a few miles from us on L.I.

You can ask if they have tested the Wolfbend system. I'll be speking to them this...
Rj-- Our bending system has been replacing that method in aerospcae fuel lines.Sound like you may be talking about Cerro bend which is a hot metal/wax that has to be melted out.Maybe there is a powder method I am not aware of also. Our sleeve remains in the annular space it does allow for...
Thanks Stan----.I found their website some drawings show bent tube bundles I have to investigate to see if they are tube in tube bundles.They look to be single wall tubes in the cylinders/containers.

Mike,
No sales visits as of yet male or female.
Bending is outsorced and may move in house for some.
So comparison is new hyd compared to new electric
precision bending and no warm up make electric look good
extra upfront cost and repair cost/reliability of electric make us wish to weigh...
I would like to here pros and cons experiances of electric benders Vs hydrolic.
Current bending needs .075 to 1.75 OD and .028 wall thickness aluminium and stainless some tubes have 8 to 11 bends .
Pros
1. No warm-up time.
2. No need to redo set-up for each production run.
3. More...
Am I correct in understanding some heat exchangers tubing is tube in tube and there is flow in annular space between tube.
If so how are these tubes bent toghether.Is there a support between them?
Our double wall bending system employes a sleeve and allows flow but is only in aerospace fuel...
At our web page(see below) we have used double walled tube bending system to describe our technology.For he purpose of other peoples Web searches and my own applications research, I am looking for other names this technology may be refered to as .So far containment tubing/piping, contamination...
Jdarco,
Thanks, Still searching Chem processing.I have found a very small niche where metal tubes are used and bent.Semiconductor manufacturing is one.Most times plastics are used(like Perma Pipe or parkers flex tubes) and pre fab double walled elbows and many metal apps also prefab elbows...
Stephen,
Not familiar with CRA?Insulation can be used but our slevee remains in the pipe after bending so I would have to reveiw design.It slips between tubes around the bend only and has perforations for evacuation.Would the forum allow a post of a pdf or my website link I think it would help...
Any company contacts invoved in systems spoken about would be helpful.Manufacturers,installers or societies.I'll be google searching shell and tube and hydrogen piping systems and other suggestions.
Specifically seeking to learn if and how other tube within tube systems are being bent.material...
