Hot Dip Galvanizing- Dipping Process....... in action

- Watch the actual dipping process in Hot Dip Galvanizing.
The formation of galvanized coating on the steel surface is process of metalurgically bonding of iron and zinc during this hot dipping process. Thereby forming zinc-iron alloy layer protecting the steel from corrossion.
So this is where little John gets it all from
This is another great vlog about another technique, WITHOUT MUSIC! Thanks for posting and sharing!

I've been doing this for the last year and even though I've already seen a couple big explosions due to missing vent holes, this whole process is fun to me. It's like an art making the steel look as good as possible. I always joke with my manager "Hey how much more is chrome than galvanizing? Our customer might not pay for this if chroming is more costly". I can suggest as well, maybe bringing the racks up a little slower.. It gives more time for the zinc to run and you won't have heavy lips or nearly as many drips in the end. Love seeing other shops setups.
Chrome plating is inferior to galv for corrosion protection, even though it looks pretty. As soon as any water and oxygen gets underneath, the chrome bubbles because it's only a barrier. Galv protects steel electrochemically and alloys at the surface so it won't peel off.
true, galvanizing is an art and it involves a lot of skills and strategies especially on challenging multi dimensional item
It depresses me about place ha
Could you please tell me what was the solution that the pipes were dipped in after zinc bath?
Thank you very much sir for uploading this video .My teacher suggested me your video . THANKS TO BOTH OF YOU .LOVE FROM BANGLADESH.

HDG Works!
I have just witnessed extraction of a Galvanized Helical Pier that was placed in-ground to a depth of 33'Ft. 28 years ago.
So after a quick rinse with the hose, the pile looks as the day it was installed. Pretty amazing!

I just got hired at the galvanizing facility here in Washington. Saw then most the material to be lowered into the kiln and then the tour proceeded 😐😐 Cool to see what I missed in person. Can't wait to get my hands dirty in the business.

That's an involved process that should be explained to the viewer. Just a thought for those of us who aren't enraptured by shinny pieces of metal.
it s an easy procedure i can explain to you.
Thanks for uploading such a knowledgeable video...
Thank you.
thank you for watching
I work maintenance in a galvanizing factory its a really cool process.
Damn you lads are some kings. I only electroplate zinc, and the 200 degree dryers i work next to make me sweat bullets enough. big ups
What a process fun watching this stuff
thank you. Though the comments here made us do some more improvements
Wow so cool!!
Not cool to Hot 460°c temp of this zincbath
Awesome dtuff. I seen a similar place In Taunton Massachusetts. Impressive.
You SAW a similar place
You didn't seen't it
INCREDIBLE!!!
An explanation of the process anf what was going on would make this clip a lot more meaningful.
Wow that very dangerous & very interesting

Amazed at all the different variations on comments of the way it’s done.
I personally would recommend them to galvanize the beam that the crane holds ;-)
Sometimes our clients doesnt want chain marks thats why we have to use the wires.

Imagine one of those wires bracking and a pole falls into the galv and it spalshes onto the poor workers, crazy crazy saftey issues here!!
Well.. you'll got yourself a rust proof armor

We opened the fume en splatter board for video purposes only.. which slides during galvanizing
Normally it is enclosed to avoid splattering workers.. no workers within 15mtrs of the galva tank during galva
Its hazardous waste..very difficult to work with..but hardwork pays
good system
Wow
It's weird the differences in how the process is done although the process yields the same result. The kettle I work on is its own structure and the cranes ride an oval rail setup. The top of the kettle closes the side doors close, the end doors close. Wish they were able to keep it recording for the actual dipping. The popping and exploding of cold steel against that hot zinc is pretty entertaining lol and for those wondering, the zinc is about 830-850°F.
this is the old design wherein there was no fume capboard then. We have to improvised the fume collector on a plant with horizontal design. its a plant 2003. But our totally new plant has vertical design and permanent fume capboard as you were saying.

For burners what you suggest which is better either c9 or gas
flange side would be more important to not have bumps or drips, who's gonna see a drip at the top of a 20 foot poll, but the guy installing those is gonna notice a his flange not sitting level, flip the angle
gravity, mate. no matter how it's hung, it's gonna have a titty on the base.
@@KeoN710 if they flipped it, the bottom of the flang would be a smoother finish, yes there will still be some build up and drips near the edges but on no critical surfaces, with a flip it can be can be cleaned up with a hammer, nothing to grind that way
@@Kyle_Harding Bro i'm a crane operator at the kettle, trust me.
@@KeoN710guy I've poured maple syrup on my pancakes once or twice, trust me, a flange doest help aunt jemima have less drips
If it was flipped it would have a few drips on the top edge of the flange, but it would be much better then a large build up of zinc on the bottom mounting surface, this way it would need to be ground back to being flat.
nice！
At one of the valmont plants someone was in a kettle explosion that guy lost his leg and over 90% of his body was burned he survived but the only thing that saved him was his face shield
Just as long as the process is not done in China.
They do not do the quality of plating US companies do.
The coating the Chinese use on the inside of galvanized pipe wears off quick, 2 years from domestic water and as well as inside when used outside for gas piping, the coating flakes and gets into gas regulators, gas valves, orfices etc.
The Chinese pipe is usually sold at box stores.
@TheSushiraw than why so many other countries copy our engineering?
Lol. Lol. Lol. Lol. Lol. Lol. Lp

If you call copying something engineering?

_Couple questions. Has the crane or wires ever failed above the molten metal?_
_What is the brown bath following the galvanic dip? Thanks!_
1. The crane has wires, but the heat dont demage the wires.
2. The brown stuff is ash, from the ammonium-zinc chloride, that burns in contact with the zinc.

I work at a Valmont galvanizing plant in Alabama and it's not uncommon to see a pole or product fall off the wire into the kettle or chemical bath tanks. We have an extraction process using long chains that generally takes 10-20 minutes whenever that does happen. I've never seen anyone get hurt from it.

I wonder if it would be a good idea to dip a vehicle frame.
Yes indeed, companies do that, they do hot dip galvanization to give best results and corrosion protection to vehicle chasis. It can protect your vehicle chasis from rust / corrosion for a long time.
This oven system uses oil transfer heating using electricity or a steam boiler?
We use lpg and automotive diesel for heating
what percentage of metals lik zinc, aluminium and lead does bath contains?
Missed the acid bath first to clean them.
they were sand blasted bro so don't need to go in acid only the flux
Watching them clear the slag off the molten zinc without respirators makes my skin crawl.. zinc oxide fumes are neuro-toxic.. poor guy probably gets the shakes every day.
Seriously. I've gotten metal fume fever a few times from zinc. I can't imagine breathing that shit in 40 hours a week for years on end. Those dust masks don't do anything at all for fumes. This company is reckless with employee safety.
Whoa!! What country is this?? Talk about shit safety.

i've been working with galvanizing for 4 years now, never used a mask when clearing the slag. some people have been there for 20-30 years and have no signs of zinc poisoning. you dont really get that much fumes coming up at you.
so sad..
Missed the explosive sounds dropping into dip
I wanted to see this as well. My brother told me this story he was told, where they'd drop the metal parts in quickly when they had visitors just because it was impressive.

First dip after zinc: Is that just cooling or is it passivation? Looks just like chromic acid.
Passivation tank, incidentally, this is the second kettle wherein the only space we can put it is after the passivation tank. Due to limited space thats why its there. ALthough a process with one step back.

Is it a type of thermal spray coating?
2:20 for the moneyshot
Why??
Way safer than my plant
What is the one thing keeping the entire industry from switching to Zn-Mg-Al ternary baths? The galvanic protection offered by those are up to a few hundred times greater than normal hot dip Zn.
Go on then, what is the one thing? My guess is money.
Mash Allah
Yeah health and safety what about splash from zinc if. A piece of steel falls off or the crane brake fails
In our 25yrs in the industry we never encountered such a problem, double checking during jigging is the key
Second check of jigs are done after acid pickling and before galvanizing itself
This is just to show dipping en pullout of items for video
Usually the fume/splatter capture board is enclosed.. so no workers are near the galvanizing tank during dipping

Hi,
Looking help from experienced people in Hot galvanise
We have started Hot Galvanise process in San Luis Potosi, Mexico and are having many troubles in getting the perfect final product. sometimes either zinc is getting burnt or sometimes the finishing is not coming properly. We know that we are missing many things to make it work.
Is any there anyone who could help us with this? Help will be much appreciated!
Hey .
I can help
Any news ?
@@jbiloajbiloa your email or Whatsapp?
What makes it stick? And can you dip things in tin? I wish it would stay that shiny. And what makes The crystals big or small?
Metallurgical bond which forms between Fe-Zn, through the electrochemical process.
In hot dip galvanising you dip the item to be galvanised into a flux tank before putting into the galvanising pot. That makes the zinc stick to the metal.
workers NEED to wear gloves...overall its SAFETY nightmare...the fumes etc
Watching the video was good enough so long I did not find people coming so close to molten zinc tank and manually saperate or shake the beams apart. Sorry to mention, the Safety part of production is in questionable be it from a developing or developed country. We belong in such time zone when Mars and moon being explored, automation proccess is highly expected around these areas of production.
We opened the fume en splatter board for video purposes only.. which slides during galvanizing
Normally it is enclosed to avoid splattering workers.. no workers within 15mtrs of the galva tank during galva
may i know what type of material u use to remove the ash from the upper bath?the one which follow the galvanized item?aluminium?ss? or just normal mild steel?
just normal MS
normal mild steel scrapper will do
We send pipes for galvaniaztion in Cavite. Now the flange seration of the pipes was covered with galvanized. HOW TO REMOVE THE GALVANIZED ON THE SERATION?

Thought that fumes from molten zink are kind of toxic?
its better to be safe and wear mask and protective face cover
My dad operates one of these cranes and he always tells me stories of how these suckers almost blow up
Yes they do if they dont have proper venting and draining holes
They do pop and explode a lot as the racks go down. If you're not careful some pops will throw zinc right under the doors at our kettle. Got plenty of burned shirts from this job lol
that is why proper venting holes must be put in order to assure that no liquid entrapment on the item
@@philgalvindustrial9381 I jist dealt with this problem literally tonight at work. 2 missing drain holes... Has to recook a part from the other shift to repickle it.
@@stormybadtype1diabetic244 if your lucky sometimes it can just be a reflux redip but missing two drain holes is kinda bad cause it can fill up and when you pitch it it will drain out the other holes and create huge icicles
What is the bath after the hot zinc tank? A cooling rinse or passivating bath?
It’s a chemical coating to stop white rust
It does both. The passivating is mild.
Question, are zinc fumes created in the process? I work in a galvanizing facility and was wondering if breathing protection should be used around the pot.
I think you have to inhale a lot of one time. But milk will help if you feel sick from it
Yes you should be wearing a respirator
I dip the products at a Valmont kettle and it all depends on which side of the kettle the smoke is blowing. The smoke at my kettle rises straight up, but breathing in a shit ton of it at one time might hurt you. Other than that it's not that bad. Just let the product cook off and by the time the sweepers walk out to sweep the ash back most of the smoke is already gone
Never thought I'd see "inhaling metal vapors" and "it's not that bad" in the same sentence, but here we are

Question to the experts! Whats happen when hit dip galvanize parts which are already hot dip galvanized??
2nd Qestion. My client requesting to confirm min 100um HDG thickness. (100um min, doestn matter the sheet thickness). Is his request legit??
WHen you dip again a galvanized product, you either strip off the original coating until the bare steel appears or if you just dip it without strippinng off, it will be very rough. We discourage regalva because if it is stripped off, the acid fumes will be thick
THe zinc coating thickness cannot just be dictated arbitrarily. The ASTM A-123 (2015) or any related BS?JS/ASNZ standards should be the guide for the zinc coating minimum thickness compliance. It will be impossible for a sheet to have 100u coating thickness. Use the International Standard in matter of min. zinc coating thickness compliance

People gotta stop using auto focus. A camera just can’t know for sure what you’re trying to look at all the time. You twist that lens, you’re all good.
Such a dangerous process
if am not wrong in hot dip galvanizing process the entire metal has to dip in one go not like up and down coz It might get crumble on the long type metals due to hot dip in one side and cold on the other side
It depends on the part. Some parts like handrails you have to stop occasionally while going down with them otherwise air builds up too fast and they float. Then they REALLY look bad. But on the way up its much preferred to do it without stopping. Otherwise you get those horrid flaky lines across the parts.
Why would you skip over the ACTUAL DIPPING part?
Looks really cool, but it's such a "dirty" process. It's relatively easy to coat the outside, but coating the inside is typically the challenge. There are new methods available that are faster and cleaner than this - but they are not on the market yet!
like what methods? can i manufacture something with iron or steel and then galvanize it?
What new methods? There is electroplating but that's almost as old as galvanising.
Why do people make stupid comments like this? Are you trying to sell me something?

@@Rakebsikdernoyon electro-galvanizing?? Is it pure zinc or mixed with other metals?
How often do you folks have problems with stickers or paint being left on the steel? It isn't much of an issue with our plant, but sometimes I still grind off those leftovers. If you've got no issue at all, please indulge me lol
chalumeau pas d autre solution
Everyday almost 20% of all stell deliveries with markings stickers and paints
I grind off the stickers and lettering that doesn't come off in the acid when I inspect the product before I dip it in the kettle and it normally comes out fine. If I miss a spot we have a metalizer guy that dresses it before it's shipped
The galvanizer could use some galvanizing.

if a wire breaks they are screwed
I worked at a galvanized place once the hoist broke and wires used to snap once a month that's why it's covered at first before it's dipped
You have to use multiple wires per contact point for heavy stuff. If I remember correctly it's one wire per 100 pounds. Boss man sees a wire slipping at all then you get the ass chewing of a lifetime 🤣🤣🤣
