commercial pictures ?

[chris watkins]

There is an unvented cylinder in there as well.... the place is at least 25°C... maybe more :lol:

So typical working conditions for a boiler engineer then !!Hot as ...:devil:

 

[Scott_D]

A bit more welding to finish these two Strebel SCB 150's off

 

[IDCHAPPY]

Not a huge Fan of Strebels TBH, can't be commissioned by just turning them on :lol:.
Needed on of their service team with a laptop to set up the 2 we fitted into master and slave.

Yeah they always send someone to commission them.

Who knows less than u about the system but can literally adjust appliances !

 

[bennygas]

Tidy job Scott

 

[josh]

Thanks miss plumb for posting,
always like geeking out on good pictures!


Missplumb, what's going on in pic 5 with the red rectangular box?


Also, went to PHEX at Alexandra palace on Wednesday, was well worth going, seemed to be more commercial boilers on display than domestic, anyway the alpha rep was showing us their 'ARES Tec' boiler, must admit he gave a good sale and I was quite impressed to be honest.
Anyone had any experience with them yet and are they any good and the way things will go?

Bit of a throttle down there. 6" to 2" in 9"? Nice weld tho, no slag and no splatter? You dad do it? Wish mine were always that tidy. Jesus some look line the lid of bait cabin microwave !

Its 3" to 2" (2" connection on the gas meter)
Its my own handy work, when you get the amps just right the slag peels it self off and you can pat yourself on the back.

 

[josh]

Where I've been this week they had to put a steel across a high ceiling garage to take garage door and motor for it so the builder welded plates to either end of it to fix it to wall with a tiny little machine that looked like he'd got it from the car boot, was hitting the slag of with a lump of metal and looked like his welds were done by a 5 year old, you would have screwed if you'd seen it Scott.

The lump of steel is now hanging 9' of the floor with the garage door on it, I'm back there tomorrow so see if it's still holding up!

 

[Scott_D]

Get a pic :smiley2:

 

[Ermintrude]

More the rods than the current surely? I usually use 2.5 3.25mm rods 6010 and 6013? Minimal spatter just that looked nice.

 

[Scott_D]

Cheap rods will spatter more. I like murex.
2.5 for tacking, routes and small stuff
3.25 for capping and filling / bridging gaps
4.0 for flanges

Have you been welding long?

 

[Ermintrude]

Started when I was 14 , on Gas and mig, playing in workshop / foundry . Only recently started on arc as got some projects to develop. It's horrific !

 

[Scott_D]

I only ever got to test standard on arc. Just takes a lot of practice, patience and a steady hand while you are getting burnt.
Once you have the right amperage for the rod size and angle you are working at it becomes easier.
With a positional pipe weld you have to keep adjusting as you work your way around the circumference.

 

[Ermintrude]

Any tips for welding up bosses onto bigger sections? Bit like fabbing up a headder?

 

[Scott_D]

Are you welding on sockets, flanges, stubs of pipe with a thread?

 

[Ermintrude]

Stubs with thread. Also few 90s

 

[Scott_D]

Lots of prep work. The smaller the gap between the two bits of metal the easier it will be.
You can drill out / blow out a hole for the branch then profile the stub to sit nicely on the pipe
Drill out / blow out a slightly bigger hole so the stub will go inside the header
Get a weld on shoe - its a pre formed fitting you weld onto the header then weld the stub onto it. eg 2" on 6" shoe

You need to apply heat to the opposite side to the branch is welded or the pipe will go like a banana when it cools
You can heat it with oxy-acetlyene or add ribs the the inside or outside
(I will post another pic to explain better)

 

[missplumb]

Yeah get someone else to do it lol!!!

 

[Scott_D]

 

[Ermintrude]

Heat opposite of headder?

 

[Scott_D]

Opposite side of the pipe to the welded branch.
You can see the ribs in the pipe on that pic. Make sense?

 

[Ermintrude]

Ah I see . So run ribs in first?

 

[Scott_D]

Yeah if you do them inside the pipe.
Work through the hole you have cut.

 

[Ermintrude]

How many ribs is there a formula? Rule of thumb?

 

[lame plumber]

watched a welder last year securing some plugs/rods into our keel, stainless steel, as the previous ones had all failed! He was one of the lads welding up our nuclear subs for babcocks I think, as ever its the preparation but once he finished the job you could only just see the weld!! sad to say the boat came back fm refit and the keel had come off and on again, so now we have 10 splatter points waiting to fail.

 

[Scott_D]

How many ribs is there a formula? Rule of thumb?

Rule of thumb - try and get the same amount of heat into the ribs as the weld.
So if you think a 2" branch will take 6 rods, use 6 rods on the ribs

If he worked for babcock then most of his day would of been sleeping and eating

 

[missplumb]

this is an old install we did a few years ago, 3x steibel ground source pumps, 2x hot water air source pumps.

 

[Ermintrude]

Love all the copper! Nice use of heat mats on ply...... One burn ruins all that work

 

[IDCHAPPY]

Man, me and a multitool with a big scrap bag could have soooo much fun in there :lol:
Lovely install missplumb 🙂

 

[missplumb]

thats what happens when you leave apprentices to get on with the job!!!

 

[kris]

Nice n neat , really neat pipework but youl have to issue your apprentice with a heat mat, i always use ply where i can, its extra work but looks neat and makes clipping easy, good job missplumb

 

[Ermintrude]

thats what happens when you leave apprentices to get on with the job!!!

Ok !!!!!! We believe you 😉

 

[mfgs]

Very nice, neat install.

 

[MarkAqua]

some of my sites. I also work at St Paul's Cathedral, Lambeth Palace (Archbishop Canterbury home), London Airports Etc.

 

[MarkAqua]

I will get pics off my old phone of St Pauls. You wouldn't believe the boilers there lol

 

[MarkAqua]

a Manor House near Northaw, Potters Bar

 

[MarkAqua]

just some more. Hamworthy's are at Lambeth Palace.

 

[MarkAqua]

just realised they're on stupid angles. Sorry.

 

[josh]

Good pics mark, i do like geeking out at plant room pics

 

[Ermintrude]

Nice and tidy, gully terminations were a bit of a letdown as was height below headder. Your installs or servicing them?

 

[IDCHAPPY]

I'd give a testicle to do some proper commercial work again 🙁

 

[Ermintrude]

I would give both of yours

 

[MarkAqua]

I'm installing again now. Serviced and did breakdowns for a few years, but got bored.

Dunno if this will work, found this on my phone from a while back

 

[Whyme]

Told me off " This video is private"...Paah

 

[missplumb]

me too, Guess it doesnt like plumbers!!!

 

[Gray0689]

Now you got an expensive wet concrete slab lol
Nice work simon

 

[Whyme]

Niiiiice.

 

[Gray0689]

Happens to is all mate

 

[MarkAqua]

Carbon steel gas line I see?

 

[MarkAqua]

no nothing I just spied it. That being said, how come you didn't just weld a gas line seeing as though the LTHW is?

 

[MarkAqua]

I see, only curious. Your own welds?

 

[Ermintrude]

Ran out of redlead too ! External plant room, small hospital?

 

[Scott_D]

Looks good SimonJohns
Are Strebel commissioning the boilers or are you doing it yourself?

 

[MarkAqua]

nice job mate

 

[Ermintrude]

It's a nicer job than I could do myself but the wiring to burner control and gas valve looks a bit sloppy?

 

[MarkAqua]

To be honest Erm' its a complete pain in the arse wiring them up. You can use Kopex to make it look neater but ultimately it will never look brilliant. You don't get right angles in cable very often.

 

[Ermintrude]

I could do wiring 100% better but would struggle to improve on pipework. Not many clips insight between the boilers?

 

[MarkAqua]

its a ridgid tri-stand?

 

[MarkAqua]

hairy muff

 

[Ermintrude]

Steel conduit to within 150mm and gland on end of it then a steel flex to burner to allow maintenance .

 

[Ermintrude]

Used to be a pipe clamp?

 

[MarkAqua]

its a ceiling brace but i wont give too much away haha

 

[Ermintrude]

Welding lug?

 

[MarkAqua]

no, it's a ceiling brace. it takes 1" tube and you stick it on top of the shouder so its touching ceiling then tighten it up to make it ridgid, good for big tube

 

[Ermintrude]

Good idea! Saves it tipping over.

 

[MarkAqua]

indeed. although I only ever use a Ridgid bench to be fair, with chain and engineers vice

 

[Ermintrude]

Most if our work involves a pipe slice and a super fire 2

 

[missplumb]

a couple of pics from a recent job we have just finished. 90kw Froling boiler out and a 200kw ETA in. Previous system was totally undersized, if all the properties on the district heating system called at the same time, then only half of them got heat, The boiler was constantly running just to try and keep up, even in the summer when there was no demand for heating, and 4000litres of buffer stood cold!!!.
We replaced the boiler, rejigged the fuel store to allow us to move the buffers (new ones fitted) and then upgraded the pump set.

 

[dave1]

Wow 200kw! Looks impressive.

 

[Gray0689]

Looks good miss
What you do with the old stuff

How much have you come on in the past while Missplumb.
Good to see you are enjoying yourself. Neat work btw :smile:

 

[missplumb]

Looks good miss

[Gray0689]

Not good what a waste
Can't you recycle them
Make a bit extra then
Froling isn't cheap stuff
I agree with tamz you work is looking excellent

 

[missplumb]

tbh, it wasnt part of our contract to remove the old gear from site and we wouldnt be happy fitting a new boiler and connecting it to existing buffers etc, if they failed then it wouldnt look good for us even though it wasnt our fault.

 

[Nostrum]

Who fitted the froling?

 

[missplumb]

it was fitted by Econergy (british Gas). it was done about 2008 so before the rhi was available. everything was undersized, boiler, pumps, expansion vessels .

 

[Dotty]

I've got two froelings I look after. Absolute poo.

I would've gone for a Hoval STU.

What don't you like about the froling croppie?

 

[missplumb]

The boiler itself was fine, weve done a few 200 kw frolings and they are ok, bit too fussy, but work ok. the problem with this one was the heatloads totalled 140kw and the boiler was only a 90kw, the buffers were 2x 1600ltrs which is a bit on the short side, and because of the way they designed and controlled it, the boiler was always trying to provide heat for the system running 24 hrs a day even in the summer and the buffers sat cold.

 

[Dotty]

What don't you like about the froling croppie?

They go through refractories like they're going out of fashion.

 

[Nostrum]

Refractories?

 

[Dotty]

internal blockwork. And arches.

 

[Nostrum]

Googled it, combustion chamber linings ?

 

[missplumb]

the firebrick linings inside the boiler

 

[Dotty]

Yep and yep.

 

[oz-plumber]

I would be very proud of them also.

Looks great - Well Done

 

[missplumb]

nice install, do you not put local isolation on the pumps simon?

 

[Scott_D]

Nice work, dont forget to ID tape the SS gas pipe:sorcerer:

 

[missplumb]

just started on a new install, replace a binder biomass boiler for a froling one and completely repipe plantroom, install buffer tank in seperate building.

 

[Nostrum]

Hi missplumb,

I'm surprised you are still working in copper on these scale installs, I would have expected LCS given the cost! Any particular reason why?

We are on a baby Froling next week, all 15kw of it along with a colossal 500 litre buffer!

 

[missplumb]

We've priced copper and lcs on a few jobs and there was only £500 in it. Then there is different cutter blades etc, and we get a decent price for whatever copper is left at the end of the job from the scrap man
the boiler we are doing is a tx250 with a 6000ltr buffer.

 

[missplumb]

boiler is in and built, most of the pipework in the plantroom is done

 

[missplumb]

biomass system finally up and running now for the fun bit - lagging

 

[gasmanrob]

2 bed flat is it?

Or or is this what there putting infront of the plate heat exchanger on a Worcester compact these days

 

[Scott_D]

2x Vaillant 120kw going in

 

[Scott_D]

2x 1000L cylinders going in
