Building Heat Exchangers

[MSLTUL]

Any chance you could update this with some text or verbal explanation (vs. music which is only good if the rest of the clip is good, otherwise it's distracting noise)? If you add some information this could be a pretty good little clip.

[ztdep]

good , My major is heat trasnfer,your video make me learn more about heat exchanger

[345jjacobs]

too small

[JADEKINGsRULE]

dude are all engeneers like stupid or what?... when u need something done.. i mean call a mechanic... otherwise u end up with a theory for everything .. and like nothing gets done:( .. engineers are so stupid... like they try 2 explain fire.. dude my socks are burning .. call an engineer 2 explain it... wtf .. over.. cold showers in -50 below ... u silly fuck!!

[scott98390]

@JADEKINGsRULE dude... like ... I mean... like dude... dude... wtf... dude! Yeah, keep knocking engineers. You're really impressing people with *your* display of intelligence.

[JADEKINGsRULE]

lol im so fn drunk right now:)

[JADEKINGsRULE]

weld well my friend:)

[JADEKINGsRULE]

i like this so much ill let u i on a little secret:) - coppyright Radiator service co. , inc 2010 - "when dry, heat exchangers like sonic showers" as in you drain them and put a boom box times 100 ... metal vibrates:) .. get rid of all your clogging problems...

[JADEKINGsRULE]

sorry for bustin your unbelievably hard stones:) HOW MAY I GET A JOB WITH U ... FIRE AND METAL .. GETS MY ROCKS HARDER THEN SuperMan"s Cryptonite!!!...

[JADEKINGsRULE]

Archemedies got the SCRW on in what 1260 bc? no wait that was the Romagina.. no the Percia .. wait no heat exchange i got it:) the gut... thermal friction through internal dygestion? no thats not it:( OH AORA BORIALIS:) ya:) eski'^mos... DUDE:) the asKmemores::) secret society of ice dwellers.. this world seems 2 ignore! I mean trythermal heat echange at lightspeed ... AWSOME... and u get 2 eat whale blubber:) wale BluBBER!! DUDE!!!

[JADEKINGsRULE]

Masterfull work ... yet u still think in such 3dimentional terms ... how am i supose 2 fly my spaceship with linniar heat exchange? .. i mean come on bycicle weel man! bycicle weel! ... evolve dang it !

[crashmaster714]

cal rods?



[engineerdr]

y the holed half plates are placed instead of using holed complete plates in between the tubes???

[shogoonn]

@engineerdr These are baffles, their function is to lengthen the path of water flow between tubes. It also makes the flow more turbulent by passing the water perpendicularily to the tubes, creating vortices. This is a shell and tube HE without the shell. A full plate would block the flow.

[engineerdr]

@shogoonn thank you very much sir.you have increased my knowledge :)

[LeiTiMM]

cade a luva do individuo ?

[earthwindwaterjunky]

Impressive.

[krupter]

what kind of bit is that on the drill ?

[apples13able]

Did the machinists jam out the soundtrack in their down time from work?

[soulfultenor]

I attest that this is a heat exchanger for steam ?

[Crosstheriver]

@soulfultenor : This is a bundle for a Caterpillar Marine Engine to replace Cat bundle Part No: 293-0009 (Old number 8L5351) used on a D399 or 3512.

[soulfultenor]

@Crosstheriver, ok 

[jrf4x4]

I have made tube plates for those several times bigger. But good work.

[slituin]

exelente video, soi estudiante de ingenieria quimica y nunca e visto un intercambiador de  calor

saludos

[neelnaitik]

great............:-)



[MirzoBobur]

it is a good video. I am a Chemical Engineering grad. student, we use HEXTRAN and HTRI to design and rate HEX. But this guy made everything so simple.

[956charger]

great video! I repear heat exchangers and extract bundles i alway wonderd how tube sheets were made.. thanks

[roidroid]

I've never seen anything like this before, it seems huge. Where will this typically be used?

[YoungJim409]

One of those tubesheets with a piece of glass about 30" in diameter on top would make a pretty cool coffee table.

[montanhatube]

If you use Cooper Fins to made it performance will be better.

Weld free header is very good option. congratulations for your company.

[geoheat]

It looks like an oil cooler for an air compressor or skid unit. Instead of brazing the tubes to the baffles, we typically use tierods in the stationary tubesheet & cut spacers. We've retubed these before and found the shellside velocity had stacked the baffles on one end. all in all it's a great looking bundle. We use crisco some times while rolling also.

[moreton2256]

fuck, thats the easy part. the shells are wherreall the work goes. stuffing the bundles in the shells is cake.

[GeorgeTheWild]

That was a really small heat exchanger. What kind of service was it going to be used for?

[raphaelvilamiu]

you weld only a few tubes to the intermediary "bareer" plates? these few welding are enough to hold them in place?

[domyaska]

THANK YOUUU

[shoesftw]

eeeeew repetitive music

[W3TFART]

@shoesftw 70's porn music !

[poncethegreat169]

***Dr. Velegol sent me here***

*^*^COPY AND PASTE IF THE SAME IS TRUE FOR YOU*^*^

[silvucha]

is is this guy using TIG ???

[Christopherabrown]

Nice work, good vid.

I wish they showed the sweat soldering of the end plate manifold.

[temon992]

thanxx 4 this video if u have more put it pelease

[lio0nheart]

this one H.X

Called

shell and tube heat exchanger

[myrdale]

Are the tubes rolled? How are they sealed at the ends? I see the drill there towards the end that you used.

[Crosstheriver]

They are rolled with an expander. The drill is an electric roll motor and it is connected to a controller that measures amperage draw. The controller is set to reverse at the correct expansion. The correct expansion is 4 to 5% wall reduction. The technician measures the ID of the tube sheet, the OD of the tube, the ID of the tube and the wall thickness of the tube. Then does simple math to calculate what the ID should be after expansion. Set controller to reverse at that ID thru trial and era.

[ryanstruk1]

what do you mean by rolled? is the tube 'crushed' against the ID of the tube sheet hole?

[ryanstruk1]

oh and is that teflon tape on the end?



[Crosstheriver]

@ryanstruk1: Rolled is a "slang" for expanding since the expander has rollers on them. The tubes are expanded with each revolution of the mandrel. The mandrel is tapered and the slots in the cage that holds the rollers is angled. So when it is rotated the mandrel draws itself in and the rollers rotate and expand the tube out. We expand until the tube wall thickness is reduced by 4-5%. That is not teflon, it is "Lube-a tube" tube expander lubricant that is water souluble.

[byjoveoldchap]

Lovely workmanship!

[akaderah]

good film

[equipman21]

i buy heat exchangers and scrap out stuff so if you know whare there is some scrap please contact me 773 331 7474

[midocrespoo]

good

[DDDelgado]

I am a chemical eng., this is an excellent video to understand heat exchangers.

5 up, veryyyy goood

[ihtxam]

same here, gr8 video.

[liyubo33]

hello

[engineerdr]

@DDDelgado nice to see a comment of a chemical engineer......i m a student of chemical engineering :)

[vitorfray]

@engineerdr he prolly is a student too, engineering students usually call themselves as engineers =P

I`m a mechanical Engineering student xD

[carlica69]

awesome!
