pipe volume

[hammers4spanner]

Seeing alot of stainless mapress these days on installs and curious if this is similar to barrell with delivering volume of gas to an appliance or is it more same as copper with volume??

 

[kirkgas]

Is it smooth bore or corrugated?
BS6891 has tables of delivery for copper, steel and corrugated stainless

I would have said it would be the same as copper. Iv been using it alot. Mostly galvanised LCS rather than stainless though?

 

[Scott_D]

Same as copper I believe.

Are you useing carbon steel on gas?

 

[hammers4spanner]

i believe i said stainless as far as i'm aware carbon is for water,heating,air

 

[Scott_D]

I ment Jimbob.
I didnt think you could get gas fittings in Carbon steel.

 

[hammers4spanner]

You cant they are stainlees yellow seals i believe , would be interested to know if you can put gas fittings on carbon steel tho as make it much cheaper

 

[Jimbob]

I don't use them for gas, I think you can though??? Just have to buy the gas seals
