Aus obviously differs from the UK
which can have distribution steam lines in screwed iron (but not with malleable fittings) as well as welded iron, pressures are generally restricted at boiler house exit, condensate lines (returns) were in my lifetime done in table 1 copper (which is threaded as well, not many around who can still do that!) later they were still in copper (table 3 then table X) but with silver soldered gunmetal fittings, today both stream and condense are being installed in thin wall stainless with hydraulic crimped fittings and ....but blow dows in seamless??? why???
LPHW central heating of almost any bore size is being installed in thermic welded plastic and for domestic use push fit plastic.
No wonder I have got 4 tons of pipework screwing, bending, welding plant that is now worthless, I was asked to bend a piece of heavy barrel the other day and couldn't even find the bender! (it is beyond reach in a corner of a shed full of 60 tons of scaffold piled in front of it)
