Ever hear of BoltTech Mannings? Induction heating.absolutely amazing.We built my first steam turbine in 1994..Westinghouse.32 half joint bolts on the IP ranging in size from 3" to 4". 3 days to get them to the right stretch using rod bolt heaters from the top down through the center and spring heaters up from the bottom. Fast forward 6 years. Teardown time.5 minutes per bolt to get enough stretch to loosen the nuts. Awesome.Re-install time was about double. Do the math. 3 days or 5 hours.
We used to make the buckets at GE Power Systems Airfoils in Duluth, GA before it was decided to move their production to Bangor, ME and have us concentrate on gas turbine blades. Those buckets were heavy.
We do use Mannings on steam turbines, not however in this case as this was an installation, so time was not a factor, on maintenance jobs though, we use Mannings, and now also a new technology, company called BoltTight.
Scott here, New South Wales Australia. I used to work in the power department at B.H.P Newcastle. and this turbine is a similar size to the "Parsons" turbines we had there and I'm like others here and it looks like is being lifted incorrectly unless there is a unusual shape on the low pressure end that you can't see. They would have lifted it DEAD straight to clear all the high pressure blades and THEN had to lift it out at that angle to clear something on the other end. Maybe??
Where I was working years ago we were lowering a 100 ton transformer with two fifty ton cranes electrically coupled and a 2 inch coupling shaft between the carriages. One of the cranes brakes failed and they bent the coupling shaft like a piece of spaghetti and spat it through the roof where we found it a good hundred feet away.. Disaster was averted when one of the crane drivers took control and started to lift the transformer with the faulty crane. Long story with loots of pooey pants suffered by all.LOLOLOL
Where exactly are the "buckets" located on a steam turbine? Steam turbines don't have buckets.They're called blades where I come from and called buckets on a gas turbine...both General Electric and Westinghouse.
rick freeman wrong. GE calls them buckets because they look like they could carry water on the back side. We made rotor 0s for up to the 9H GE gas turbine and all gas rotors looked like normal Airfoils.
These used to come into our shop damaged and I had to use a TIG welding setup to get them back to working condition..GE was one name I remember that was shown to us on repair orders..I don't remember the model or part number..just told to fix them right which I did.
It is being lifted straight the different size diameters makes it look like it's not level. If it were not level the last stage buckets (blades) wound have gotten damages and bent.
Heavy duty Turbine will be lifted in balancing, leveling and carring to avoid damage the equipment. ( profer tools and lifting materials is verry important with people havingh a good knowledge and expiriences in lifting)
Hello everyone. I have 2 routers of turbine, made in stainless steel Magnetic Deplux 2205 made by Hitachi Japan. I want to sale. +923218184574 WhatsApp number. emraan.kamboh1@gmail.com
I couldn't agree more with all the other comments about how it's being lifted on the piss, fuck what a rough bunch these guys are, thought I'd add my 2 bobs worth there's no protection between the steel sling and the machined surface, plus check out the dude putting something between the machined couplings to "protect" them . Does anyone know what country this is happening in.
Is it just me?? But, It seems like a main shaft diameter of @ 2 feet is Really overkill for just a whole bunch of rather tiny blades? Oh, I know. It is heavily and correctly engineered! But seriously, To just look at it with an open mind, one would really have to ask. Does it really Not Look weird to have such a HUGE main shaft diameter for just a whole bunch of rather small blades??
Late answer: Don't underestimate the power of centrifugal forces. And even more: you can't afford that to break, because the very high energy that are inside those disk can cause serious harm if released. Source: turbine engineer here

c est vraiment beau ce vidéo
Where's the shaft guides? They were supposed to have been bolted on long before the shaft got that lo.

+scott carr They were probably there for some work experience!!!
I would say no optical illusion just a lot of damaged LP blades but that's engineering for you.

A GE é foda.
Why is that shaft being lifted at an obtuse angle to the housing? Unless the nozzles or stators are removed some one should get a telling off.
nndorconnetnz and you'd be the expert sport.
I am an expert and he is right, the quickest way to bend the blades and damage the diaphragms.
YOU AIN'T LYING! unless it's an optical illusion, and it's not, they must be trying to trash the buckets, diaphram, shell and all.
Where this is recorder?
Turbina a vapor, basicamente gera energia.. É assim que se cria energia em usinas nucleares ou carvão.
You just DON´T want to drop that..

I work for GE and I had a hand in machining this rotor.
Roundness of this turbine surfaces can be measured with RON-Pilot tester
You guys need a top geezer on that job

у нас на ТЭЦ конечно же есть турбинные роторы, но после эксплуатации более 50ти лет они уже иначе выглядят..
They get lots of wear on them and some can be repaired and re-used.
The rotor was level, to within a few thou.
alquem pode me dizer oque é isso? o que isso faz?
The shape is roughly that of a Schlumberger vortex

Engineering is Great
You fail Sir,
I happen to know that this rotor was lifted level every time it was installed/removed from the unit.
make no mistake, that would be costly if it fell..

Actually the diameter of the main shaft has to be made large because it is hollow. Thats were they install all the nuclear powered hamsters.
Dude we are supposed to keep that a secret ....
Why did they take it out on this video?
It's good but it has some disadvantage
WOW!
it's an A15

I think it's france, but standards differ. Cost and time lost fixes those issues. Expensive lesson huh?
Implosion technology in our faces
That's lp rotar

Thought the same thing.
This showed very unskilled worksmanship obvously had to pay a heavy loss.
