track pipe in concrete

[Ermintrude]

Stan, think sleeve needs to be non combustible and mechanically stable. Bit of iron tube? Or copper?

Trac pipe classed as pipe in pipe so along as both ends are above the finished floor it can vent itself if there is a leak.

I agree with that but had a quote for track pipe and nearly had a hart attack , so thinking of running 28mm copper in 1" 1/4 and each end venting out . Is that ok?

I agree with that , but track pipe it self is stainless still with some plastic cover and we are allowed to put that in concrete without additional protection , as long as there is no joints !!

You can use the plastic coated copper

 

[Ermintrude]

Plastic is bonded directly to stainless so no void and is not classified as a sleeve but mfr provided protection.

Don't think any gas pipe can be installed in concrete. Screed yes.

If there is 50mm of screed above duct plastic might be acceptable but I probs use denso when in screed. But I would in this situation mix a screed up and place it around denso pipe or use a steel pipe as a sleeve ( when poss)

Yeh it says concrete then says pour screed. You can install in screed but not a monolithic concrete slab due to structural forces on pipe.

 

[Ermintrude]

Check your viper book or what ever training material you have regarding pipe work

 

[Atouchofgas]

Yes, if you read further down 8.4.2 etc it's say you have to protect it against movement in concrete.

There has been a lot discussion between regulators and Tracpipe over the years about this question. I think it came down to following Tracpipes installation instructions.
