Are Asbestos Flues Still ok to be used?

[arran197]

I have never done any work on an appliance with an asbestos flue. I know very little about them. Just recently we've been going to an estate where we've come across asbestos flues which are still in use for the gas fire.

Now I went to one today and it had been classified as ID. The only reason given was that it was asbestos.

So is it still ok to be used in an existing installation? Providing it passes the flue flow and other tests. The only thing I could see wrong with this was that it had metal strap banding to support it on one of the sections. Which is another question, open flues, if they're strap banded or not supported but are strong and rigid, what do they get classified as? My understanding is that the recent changes to supporting flues only applies to fan assisted flue systems, which is now at risk.

Please enlighten me on the galvanised band on fan flued appliances . I would not think anything of an asbestos flue and I work for social landlords. If it passes tests and isnt degrading causing a potential risk I can't see the problem .

A working asbestos flue isn't ID. Id means it's about to kill you as of now..

O banding, all round banding, builders banding what ever was used a lot and as long as the joints are fine and it is supported i would class as ncs

punch band

I think it may be the case that the housing association don't want it there as they are taking it out and want it replaced with twin wall.

The banding I am on about usually comes on a roll in a box. It's about 10mm wide and is a flexible metal band with holes along it. It's flexible and not really suitable for supporting flues.

I'm under the impression that on open flue it's ncs, on fan assisted it's at risk.

once people know there is ab in there house/flat claims start going in

punch band or roll a band not for sporting ab flues tho

If used correctly galvanised band is brilliant for supporting vertical flues in lofts much better than flue supports in some cases. Wasnt aware there was any issues using it providing a flue is adequately supported.

you cant use them to support flues no more i was reading in the gas safe mag has to be mi brackets

Another money making spinner by manufacturers.

yea and no on long lengths of flue the punch band is rigid and can sway

 

[wattsie1987]

Not if fitted properly with battens across the trusses and the band wrapped round the flue and screwed so it tightens tightens. I honestly don't think I could shake a joint loose if I tried on installs I've used it.

yea but its the people that dont do that thats why the dont allow for new installs

I came across an OF boiler the other week with an asbestos flue and seal was degraded, double checked with local gas centre tutor where I take my ACS (hes an ex Corgi Inspector) and he said repack it with fire cement carefully and record it as NCS but its fine as long as it then passes the flue flow test.

You can't use it any more I'm afraid. Has to be rigid clip. We use the multifit pipe support. Found they are the easiest to retro fit. I've used the glow worm ones before and they're good apart from the wall bracket holes are too big and you need a washer with them if using normal wood screws.

The no galvy banding rule is retarded...

The problem with the galvanised-band is that it tends to pull on the flue and it moves. A rigid clip shouldn't do either and so keeps the flue it's it's correct location.

and bad fitting of the galv band

speak of the devil just seen this (i didnt take the pic)

Wow that's super rough I think the issue here is not the galv band but installers that don't have a clue. String may as well of been used in this instance!

another example of engineers not being able to make a decision using experience its by the book or not at all these days
