Is this metal flue likely to contain Asbestos? 1960s semi

[agulesin]

New owner of 1960s semi here. I've been through a lot of the Asbestos posts on the forum but can't find an answer, hence asking.

The metal flue in the photos runs from the kitchen ceiling through the back of the airing cupoard then roof. I'd like to remove it to make space, but i'm wondering whether I'll find asbestos gaskets in the joints. Apparently there used to be an air duct heating system before the combi was installed.

I've downloaded the HSE Asbestos Survey Guide (https://www.hse.gov.uk/pubns/books/hsg264.htm) as recommended by someone on this forum. It contains reference to metal flues called Durasteel:

Flues for wood-burning stoves were commonly constructed from a metalasbestos where the asbestos was added as insulation between the inner and outer layers of stainless steel to give a high degree of insulation when passing through floors and on the outside to prevent sudden cooling of the flue gases. ‘Durasteel’ metal panels were used to provide a strong construction with a certain degree of insulation, by incorporating a layer of asbestos paper.

Can anyone please advise on what this flue might contain and the amount I'm likely to be faced with? I'm assuming that I can remove it carefully with the right PPE and take to the local Waste Disposal centre. Thankfully I've had Asbestos Awareness training at work so have some idea what I'm looking for.

Thanks in advance for your help

Stephen

That looks like twin wall gas flue selkirk i l or similar just locked together metal joints no gaskets involved.
