Do people still use BSP threaded pipes? I see them for gas on the outside of houses. And it struck me that it should be impossible to tighten them fully - what's the chances of the corner piece facing the right way?

Excellent, if you know what you are doing. I installed a combination of
2" and 1" steel pipe for airlines around two factory units, with
multiple branches. They all ended up facing the right way and there were
no leaks. You just need a couple of good Stillson wrenches.
BSP threads are available in both taper and parallel. The taper ones
seal on the threads, while the parallel ones use a sealing washer -
often these days a Dowty washer or similar, although I have seen OLD
specifications for "greased leather" washers!
IIRC it is known as maleable iron. I used 1" pipe as conduit to carry
network, phone and coaxial cables to the workshop, I used quite a few
conical couplings on the 70' straight run. this let me feed 6 cables
simultaneously up the pipe. Even then, the friction was a major problem.
The bends were female and aligned as required. The run needed to be
water tight, probably is airtight.
Wh not use nice copper pipe and compression fittings? What are you using outdated technology for?
