Ask the lads at Esher. We carry it in our central depots, but not in all branches. If its just a one off, then the lads can get it next day from internal distribution, or Paul has the discretion to carry a bit of stock if you are using it regularly.

 

[mutley racers]

Thanks ray. Much appreciated

 

[Ermintrude]

BSS have tube stock or if you have retail premises get an f&P wholesale account?

 

[hammers4spanner]

have i just read this right you cant get pipe from pipe center???

 

[Ermintrude]

Yep , not all pipe though225mm and 375mm is a non off shelf item and vulcathene always instock in a place just out of reach!

 

[hammers4spanner]

the big stuff or specialist is never on shelf due to cost , just installed abou a grands worth of vulcathene but they had that in staock due to it being school closing time

Haven't you noticed during downturn everyone's reluctance to keep anything in stock? Good business sense but pretty annoying at 16.30 when u planning to work late and finish off!

 

[SimonJohns]

I do alot of steel. And the best place I have found is bss most stuff in stock and next day if not

How much you planning on doing. I've just done about 6k in tube and fittings ok one job

 

[mutley racers]

I just needed 1 length of 3 metre black iron. Williams and co can get it next day but not for saturday. So I tried bss but they out of stock. So then tried pipe centre who have. I didn't realise how much it was. One wrought iron flat faced union costs £66+vat.

 

[SimonJohns]

Don't pay that

I only pay £30 for a 4" elbow

Tell them to get bent and give you a decent price

What part of the world are you in?

 

[SimonJohns]

Btw. Use copper face. You'll get a much better seal

 

[mutley racers]

Am in hampton court. But the place is london ealing. What is copper face? I have no choice but to buy it as the pipe that needs cutting into has no movement so need a flat face union. It is wrought iron though, usually for steam. Is that ok for gas?

 

[mutley racers]

Bit gutted really as a normal ball joint is only £7. This is 10x the price

For future, does anyone know where I can get these for cheaper?

 

[stevetheplumber]

use a long screw con for gas dont think unioins are good for gas

 

[mutley racers]

Its not me who is fitting it. I am just purchasing what the commercial guy tells me. It comes with neoprene washers so maybe that helps

 

[tamz]

What size pipe and fittings is it?
You can use normal MI or galvanised.
A 6.5m lengtht of 1" mi galv is around 30 odd quid. Split unions are about 3 or 4 and bronze to iron about a pound dearer

 

[heliotrope]

Your'e not a million miles from Croydon (well about 45 mins)

Harris and Bailey have all you would need in stock.

 

[heliotrope]

Think long screw went out with the Ark

I am pushing 70 and only come across long screw on gas about three occasions.

Unions have been used for many, many years now:smilewinkgrin:

 

[hammers4spanner]

Need a gas union mate make sure its gas due to the seals. 66 quid plus vat does sound dear tho I have mis judged barrel tho has a habit of putting a dent on pocket .

Is this pipe being welded or threaded and is it underfloor ?

 

[mutley racers]

It's being threaded and is a vertical run in a room. So not concealed. I see you can use wrought iron fittings on gas but not wrought iron pipe with gas.

It's inch and half. For a 3 metre length in bss it 33+vat. Need the special flat faced union as no play on the pipework for normal union.

I thought you weren't allowed to use galvanised on gas

 

[SimonJohns]

You don't need a flat faced. A copper faced standard union is fine

 

[mutley racers]

You don't need a flat faced. A copper faced standard union is fine

Really? With this fitting they won't need any play on the pipe? As it comes up through a concrete floor and up into a concrete floor. So no play at all. And will I get this from bss?

 

[mutley racers]

Picked this up today simon johns. Is that what you were talking about?

 

[SimonJohns]

Yes. Use a little jointing paste on the face to aid the seal. But the copper faces will seal better than iron only

 

[Scott_D]

You will still need a few mm of play between two fixed points with those unions.

 

[mutley racers]

Yes a little bit of play, a couple of mm am sure they can get. better than the other unions. And it was only £19 from Harris & Bailey. (Big thank you from heliotrope for pointing me to them). What paste do you guys use?

 

[Scott_D]

Jet blue for me. Does everything

 

[Dotty]

Jet blue all the way. I use straight wrought unions, no bother with a bit of paste!

 

[mutley racers]

Jet blue all the way. I use straight wrought unions, no bother with a bit of paste!

Straight, as in flat faced?

Jet blue a, I tried to get hold of some today but to no avail

 

[Dotty]

straight, as in common or garden. I actually have more trouble with flat faced unions.

 

[mutley racers]

I get you now cropster. Don't know about having trouble putting them in, but, trying to get hold of those flat faced unions is a nightmare. I hope the above one will judt manage it. Otherwise it is off to plumb centre for a £66+vat wrought flat faced.

 

[mutley racers]

Are you not able these days to just thread the pipe a bit longer and then use back nut? With paste it wouldn't leak like ptfe does if you unwind it a bit after tightening it up too much

 

[tamz]

I thought you weren't allowed to use galvanised on gas

Every riser in the country is galvanised

 

[hammers4spanner]

Use loctite 55 on your threads mate with bit of gas paste ,

like simon says i use bit of paste to aid the seal gas paste on gas but each to their own

 

[hammers4spanner]

thought you had a commercial guy in helping you thought they would know what to get do mate

 

[mutley racers]

Yes a couple of commercial guys doing the job tomorrow. I just had to purchase all materials for it

 

[hammers4spanner]

bet those two aint cheap !!!

do you get much commercial work?

 

[mutley racers]

Am getting quite a bit of commercial work now. Mostly due to churches passing my name on.

For the 2 for the day £500. Which I think is reasonable. then £90 for nitrogen to purge system. It is a bigger job than I realised really. Plaque heaters with pilots that need to be re-lit and that requires scaffold. Will remember next time though to add more to my quote.

 

[mutley racers]

Every riser in the country is galvanised

Oh ok then. I didn't know that

 

[hammers4spanner]

remeber commercial means ££££££'s

am getting offered fair bit so looking at booking my tickets as getting fed up subbing it

 

[heliotrope]

Use loctite 55 on your threads mate with bit of gas paste ,

like simon says i use bit of paste to aid the seal gas paste on gas but each to their own

It's very late, I'm quite old and I have quaffed getting on for a litre of the red stuff but without
resorting to the regulations I am fairly sure that you can only use one or the other on gas threads
but not both.

 

[tamz]

The fm companies have the good stuff signed up. Most of what is left is the dross with the odd good one here and there It depends what you are being offered. The money isn't really any better you're just not knocking your pan in to make it.

Thats what i'd say too. And, only hemp on joints 3" and over which is now all welded anyway!

 

[hammers4spanner]

As far as I am aware you dont need to paste loctite but not read anything saying either but then never seen nothing on pack olives saying same I do it because always have

 

[mutley racers]

Well, that was an interesting day. After all that effort sourcing pipe and materials I turn up to the job excited to get started. As soon as the commercial guy turns up, he looks at existing pipe and mine and says, that's too big. This is inch and a quarter and I have inch and a half. Luckily the pipe has play on it and he has fittings on the van.

Then off to look at the meter, the meter does not have a purge point on it. And, there is no chance we can purge job just by air, so need to use nitrogen, but no place to connect it to.

Then were off looking for another plan. Go upstairs and he spots plaque heaters with no ventilation. Says, that's not good. So we ask to look at cp12 of the commercial type. Plaque heaters not listed on it.

So we find an iso valve at kitchen which is inch and a quarter reducing down to 28mm. He says that is your best option. So that gets tee'd into and another valve and test point put in.

I am wondering, from this iso we put in, could I bump the diameter upto 32mm if I needed? As we all know gas compresses.

Oh the joys of being a plumb bum.

 

[hammers4spanner]

purge commercial pipes with air??
5-15% explosive ratio ?
isnt that dodgy?

 

[mutley racers]

The guy said he would never be able to get all the air out without nitrogen. Something to do with all the plaque heaters and nightmare runs of pipework

 

[Dotty]

Every riser in the country is galvanised

And LPG has to be in galvo, not wrought. Because of the moisture content of the decompressed gas.

Thats what i'd say too. And, only hemp on joints 3" and over which is now all welded anyway!

oooo hemp! no no no! Anything up to 1" with any pressure can be screwed or welded, Up to 2" and 500mbar can be screwed, anything over 2" or over 500mbar welded only.

I've just corrected Tamz! I'm going to that special corner of hell reserved for people that dare do that!

purge commercial pipes with air??

Aye. indirect purge through a stack! doddle!

Mind you, I don't do any calculations, I connect the compressor and give it stacks!
