I've seen plenty of examples of MDPE brought up on external walls usually

I've got some exposed MDPE pipe feeding a tap outside a stable and
tack room. It's been there for upwards of 20 years now and must have
been frozen a few times at least. It's still watertight.

There's also some up in the fields feeding a horse waterer and that
generally survives the cold too.
