Condensing Furnace Exhaust Question

I have condensing furnace. I know the exhaust makes condensation. The piping all slants back to the furnace for drainage.

Outside the exhaust is about 1' in length off the wall of the house. That pipe too also has slope back towards the furnace. However, when looking into the pipe I see lots of droplets of water beading against the inner wall of the pipe.

Is that normal? How come these droplets don't freeze?

Tried to edit to add that I see the droplets/condensation on the inner wall of the pipe when looking thru the fitting at the end of the termination outside on the side of my house. Is that normal to see moisture in there like that?

Yes, it is completely normal. Even if those droplets freeze while the furnace is off, within a VERY short time after the furnace fires they will melt. Not to worry.
