Pipe identification

lmorsino

this is a picture of a drain that is in my basement floor, near my furnace. i would like to drain the condensate fluid from the furnace into this drain. the condensate is slightly acidic, and i have heard that if the pipe is made of galvanized steel, it won't stand a chance. if it is cast iron, it will be OK. is this true?

i know its hard to tell as the pipe in the picture is 72 years old and there's a bunch of crud on it! but is there any way to tell if it is galvanized or cast? it is 2 inches in diameter and there is a slightly rusty hue along the inside rim, which leads me to think it is cast iron, but i wanted to get a second opinion. all the other drains in the house are cast iron. any help is appreciated...
thanks

That is a picture of an old bell trap. It is made of cast iron and set in concrete. Directly under the trap it transitions to 3 or 4 in. clay pipe.
you will be fine to drain into it.

Thanks everyone, for your opinions!

I see you got your answer from professionals that work with those.

For future reference, in a pinch you can tell the difference by lightly touching with a grinder. Cast iron will have very few sparks and they will be red. Steel will have many sparks and will be yellow.
