where to buy iron fittings for gas???

[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.

 

[mutley racers]

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

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

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.
