Low pressure steam boilers transfer heat at pressures between 10 and 15 psi with a temperature of 300° F (149° C). This type of boiler is used where there is little need for rapid temperature change, where a consistent temperature is required. The popularity of low pressure steam boilers is due to the speed at which they deliver steam; they can do so much faster than high pressure steam boilers.

Wow!! bringing back memories. Fire tube boilers I use to operate & maintain when I lived in NY. For that manhole/gasket to be in that condition
Building Engineer not doing their job. That’s routine maintenance task. Nice job/repair like always.
Do working around boiler equipment damage hearing?
@@bunnyman6321yes
Yikes. Rotted cleanout on a big boiler. That is very scary. 😮😮😮
Wow good job. I use to work on Clayton steam generation boilers. They had a operating pressure of 450 pounds. I retired from HVAC 31 years Union. I don’t miss working on steam. Be careful
I find it easier when you put the manhole cover back on to wire it up to a piece of pipe that is in line with the yolks and over the opening. This way you don’t run the risk of dropping it in the boiler and you can line up the gasket easily
Please be very careful- should have been a physical LOTO (lock and hasp) in place instead of an on/off switch on gas burner.
I miss working on Boilers, great video keep them coming 👍🏻
We had a 150hp fire tube boiler (230 psi) that fed presses and a low pressure heating loop. The main output nozzle sprung a leak midday and roared like a jet engine for hours even with the blowdown wide open. The entire room was engulfed in steam and you couldn’t see your hand in front offyour face. The boss tied a rope around his waist and shinnyed along the floor to reach the main disconnect and threw it. We called a welder in and he spent 4 days laying bead around the nozzle and a generator truck and annealing blankets ran all night to keep the weld soft.
Your videos are King bro you do a very great job on all your jobs.
Interesting and helpful video. Well explained. Great job 👏 JMT. And special thanks for the clip from Seinfeld 😀😎. My favorite show
intense! great content. I enjoyed the show clips too, surprise bonus🌟🌟🌟
Dam that boiler room looks like a Dump - My boss would go off on me if I ever let my boiler room get like that
Ahh, when that nut released?? Ahh, great sound. 👏🏼👍🏼💪🏼
Good job Jumper, Looks like a large pressure cooker.
Was a control tech for boilers, use to change those gaskets all the time. Looks like a Superior boiler
I am surprised that boiler where opening for the inspection where all the manholes cover, and low water alarm not taken apart. and most manhole cover are 11 X 15
nice work, be safe.
Sir
If you bolt & nut difficult to loose and open just warm with torch so very easy to open & time save
Liked the boiler content
If you would have locked the second boiler's Honeywell RM78XX control on "Prepurge" for the night, the boiler would have been nice and cool on your return. All of the limits and safeties (ie, low water, etc.) need to stay made for this to work.
You can split a tube in the hot pass weld and stretch the rear sheet by doing that.
When you can get yourself a Milwaukee impact 20v with impact rated socket ends and you’ll bust those out in 2 seconds great vid.... my truck got broken into 3 different times... all in Miami. The slick locks are a pain but since using them I haven’t been broken into...
A curse on those who steal tools from the working man... they’re scum
Literally stealing a mans lively hood. Indeed scum.
Milwaukee makes 20v tools?
Which supply store did you find the manhole cover at ?
Loved the Seinfield reference
No anti sieze?
Good video 👍 buddy
Super
Nice
Bro why the hell are you using a pipe wrench on a hex nut? Hack.
They said earlier in the video that a bunch of tools got stolen from their truck, including their socket set. Even so, since they ran to the supply house, surely they could have picked up another socket set...
Damm as a licensed engineer I say that boiler room is nasty....great video, ive done some jobs like that in my work boiler room..
Are you guys in NY required to have a stationary engineer license? Down here in Texas it’s required. Thanks for the videos
Only if you're employed by that specific site. If you work for a boiler company, you don't need it
What part of Texas you in?
Man. Grab some baking paper and put a ring underneath the gasket and above the gasket. It'll seal just fine and you'll never seize on there again. If nothing else use some antiseize for the next guy, who could be you
👌
👍
Have to isolate that boilers king valve. Just a thought
Proper Mechanical and Electrical Lock Out would have / should have needed to be carried out... Work Permits Issues and signed onto, Pipe Spades Fitted , Electrical Panels opened Up Fuses Pulled and Isolation Lock signed out and Fitted...Utilities Operator instructed to drain down the Boiler and Vent the Boiler, remember a Leading Hand Millwright friend of mine just got stuck into the job like that during a Annual Shutdown... in the times when Health and safety wasn't taken like it is today, but someone had broken a steam condensate line above him by a a Steam Calorifier above him, next thing a pump started and emptied hot condensate somewhere else on the plant and hot returned condensate water hit him down the back of the Neck...scared for life with third degree burns loads of skin grafts, never worked again... still in constant pain...Be SAFE, careful out there...Great Upload...
This may seem like a simple fix and it is but mind u he has a man helping him picture doin this by yourself. I work in Connor I’ll boilers now local 638 nyc and for those boilers to b in this condition they are not being properly overhauled yearly like they should
That has to be a low pressure boiler for it to have 67 float on it. They don’t open that up every year at all.
How tight? Yes.
Crazy how careless people can get when working with pressure vessels. That's year's of neglect. 15 lbs of pressure may seem like a small amount but on a vessel that size plus all the piping it adds up. If that man way would haved failed exposing the water to atmospheric pressure the result would be catastrophic. Boiling liquid expanding vapor explosion.
When I saw the condition of these it gave me chills. 😮
Why did you replace the nuts ?
Why not?
If that supply house was in NYC it's either H&L or AF
So many things done wrong in this video, including man way cover gaskets are not some obscure size.
Large boilers lol. When you open a drain, always open a vent.
I work on steam, LTHW, chilled water etc as an apprentice, recently experienced water hammer absolutely terrifying experience
Highly recommend telling your employer you need a 36” or a 48”
Can tell no water treatment!
No water treatment, nobody blows down and tests those little #67 LWCO's. Because nobody cares.
@@johnwilcox4078I do every day at work cuz I’m bored 😂
@@sc1338 Well keep up the good work 👏 😉
As soon as I saw them just dumping the hot water content down the drain I figured there was no water treatment. Or at least not any more 🙂
Also no one is doing internal inspections if those gaskets are like that, imo
My two 125hp steam heating boilers have injection quills feeding water treatment and I tear them down every year for cleaning and inspection in the off season. I really don’t like surprises during heating season
I would not call those Large...LOL...
Me neither. Those boilers are only 50-100 hp, that's actually small. The guy said it's the first time he changed a manhole gasket,lol. But that #67 LWCO looks scary, should be a #150.
Steam boilers are a pain. Give me hot water boilers anytime!
15 pounds so that thing operates at roughly the same pressure as an average car radiator is what your telling me
Watched less than 5 minutes. "Man look at that bolt"... Have you ever done engineering before!?
They over tightened the shit out of those nuts...Probably why it failed...
Where is the chief operating engineer?
No one gets back to you
Perhaps you're not really authorized to do the work
