Is it for gas?

If not, you could try electrical conduit, which is 25mm diameter.

There are a number of different grades, but you should probably consider
hot-dipped galvanised (as opposed to electro-galvanised).

Have a look here for specs:

No - it is not for gas but it must have the same or better strength.
I fear your conduit is of a lesser wall thickness.
Thanks for the suggestion anyway.
