I saw your process is welding first, expanding later. Sometime, i see other manufacturers do the expanding first

How to set temperature on Dune 4000 B

Incorrect Sequence... Wedding of tube to tubesheet and then tube expansion

Hi, boss, I'd like to share the Tube to tube sheet Automatic orbital welding machine with you, which can improve your working efficiency and welds quality, and save labor cost and management cost for you, please check the video: ruclips.net/video/diIzqK4Vjdc/видео.html , and the Automatic tube assembling system for boilers or heat exchangers, refer to video: ruclips.net/video/h2WzmZapX7o/видео.html

Totally tubular! Non-mechanical mixing for better temperature uniformity. Greater temp diff = more conducting. This prevents fluid at walls from getting much hotter than center and reducing heat transfer rate.

DBXTOOLS manufacture TUBE EXPANDER.

beautiful work well done

Kolay gelsin 👏

Nice job guys !

Got it perfectly

Now it is need to be inspected by QC. Please do contact me to get it inspected for further job clearance

✌️

Weld stress and thermal stress relived after completing...??

en otro video vi que primero hacian la expansion y luego la soldadura

Amazing!

Excelent

Good job

Just like a magic. Good job.

Hi, do you think such a helicoil placed in the pipe flow, Before a bend in a pipe could elevate the ware often found on inner side of the bend, this area often showed more ware and pitting. Due to the flow force hitting this bend, pitting exassabating its self enlarging in flow action, where such as you demonstrate, could possibly deminish such full on force travel round bend,? Interesting And... Thanks for the reply LOL 😂,.. Thom in Scotland.

Great！ and when you may need large and precision tube sheets， please feel free to contact us, www.cncmetalworking.com/case-study/tube-sheet-for-condenser.html

What is the diameter of tube used in this shell and tube heat exchangers?

I am a mechanical engineer. Can I get a job here.

what are the flow rate in each pipe?

Is the corrugated tube just a spring looking object in the tube or is it swirls cut into the tube?

Would this help a car exhaust system or would it screw up the back pressure?

the only thing "wrong" with the explanation is that the bubbles in the right pipe are not moving erratically. they are moving along the lines of the vortex motion created by the spring. that "turbulent" flow is more precisely stated as vortexual flow

what software you are using for the simulation?

What is the diameter of these tubes?

it means its better to use corrugated tubes ? you get less turbulence ? i'm investigating how to reduce turbulence...

freezing in the heatwave environment

interesting! no more worries about dry out.

На самом деле это видео заставляет усомниться в непогрешимости законов Ньютона. Движение материального тела обязательно должно учитывать вращение!

Awesome!

Do molecules inside our blood flow slower on the edges of the blood vessel vs. the center of the vessel?

Excellent video. Very didactic, and can very well understand its use, its operation and its advantages. Congratulations.

Muy bueno!!

good for u guys

Cool!

The flow rate in the laminar tube is made as a function of the friction factor that the tube wall produces. The friction that the tube wall applies on the fluid slows it down at the edges which makes the bubbles move slower as well. Towards the middle of the tube, the friction of the surrounding fluid molecules as a result of the tube wall is decreased so the fluid (and therefore the bubbles) move quicker through the tube near the middle.

i understood completely what was done in this animation. good job

@KevinLiddellJohnson : In fact there was no flow rate in the experiment. The bubbles were freely ascending through the glass tubes, water filled, vertically mounted, and illuminated from the bottom. The apparently different flow rates are due to the fact that in the smooth tube your attention is inadvertently fixed in the bubbles near the tube walls, which are also relatively more compared to the bubles in the inner flow, and move slower due to the laminar flow effect too.

@FunkadelicSixties In a word yes.

Very well explained, makes perfect sense to me... thanks. Thom in Scotland.
