Adjusting metal soil pipe

[lostinthelight]

FFS! is it magnetic or not, did it spark when cutting, was there a lot of dust,how thick is the wall

 

[Jupiter01]

yes, magnetic externally.
Perhaps 5mm thick and there were lots of sparks!

 

[lostinthelight]

Is it the same material right through the 5mm thickness?

 

[Jupiter01]

yes

 

[lostinthelight]

galvanised steel then, no worry about asbestos
I must admit when I first saw the fibres on the cutout asbestos did cross my mind but thought more likely to be off gloves or other item of clothing

 

[Hugh Jaleak]

yes, magnetic externally.
Perhaps 5mm thick and there were lots of sparks!

Christ, that's a new one on me. Must have had some left over water main, so used it for soil pipes.

One further question on this please guys and happy to start a new thread if that's easiest.
How do I go from 110 plastic to this - being used as the vent pipe:
View attachment 171441

It looks like drain downpipe to me.

Looks like a 3" ( 82mm ) Osma soil bend, post a pic of the upstairs vent pipe as it is now.

I had a $hit day today... Just sayin'

Guys, I need some help with the smaller section of this soil pipe please. The bane of my life!
As seen from this image, the 110mm soil pipe then connects to this smaller grey pipe which acts as the vent. Eventually pops out of my roof.

I went to Wolsley on the weekend to get a couple of elbows and adaptor which goes from 85mm (measured externally) to 110mm and they wanted £60. This seemed extortionate!

Is there something I could do cheaply given that its only for air and will be boxed up?

I can see online suppliers for 82mm pipe but I am concerned that it may not fit when it arrives...

 

[JimCrow]

Do you still have some 110mm soil pipe left over?, use a bit of that and two 110mm 45 degree bends and slip the 110mm pipe
over the 3" steel pipe and seal the gap. 85mm pipe and fittings have always been more expensive than 110mm.

 

[Jupiter01]

That's a genius suggestion! Thanks
Yes, I have 110mm pipe and will do what you have suggested. On the sealing part, can I not buy one of those rubber adaptors if they aren't too expensive?

 

[denso13]

can I not buy one of those rubber adaptors

Yes, something like this https://www.drainagecentral.co.uk/Flexible-Coupler-Plastic-to-Plastic-110mm-x-82mm-BFC44

Update: Got the two bends and had to make do with one of these an duck tape over the top. The seal seemed pretty god but I thought the duck tape would provide further protection.
