Name of this HVAC pipe, pic included

What is the name and purpose of this pipe ?

Condensate drain line.

Yeppers, “disconnected condensate drain line”.

Kinda scary that you didnt know that.

…in southern calif. 99 percent
of the units are on the ground split with the heater
in the attic…you just dont see them. I knew it was
a drain…I just wanted the correct term.

thanks for the correct term

Looks like a “Disconnected” condensate drain pipe, and I’d be commenting on it in my report.
