Not really, there are tiny lumps all over most of it.
It is pre galvanised pipe that is pipe manufacture GP SHEET/COIL
Depends on how long the pipe is

You will want to put a length of copper into the fitting and solder it before you put it on the galvanised so that you don't cook out the pipe dope. >>they also could have soldiered on a flange on copper and thread on galvanized pipe.would have been another choice

Yes, this is often done in well systems by using a mechanical fitting on both. ie, a fitting glued to the PVC, that can be threaded onto the galv. pipe.
Black pipe is used mainly for gas lines. Like it's name it is black in color and made from a heavy gauge steel. Galvanized pipe is pipe that has been coated with a material that reduces the effects of rust. It is silver in color.
The base metal is iron - the active metal is zinc (galvanized)
there is difference in material ms is mild steel and gi is galvanised iron, hence the properties will be different
It depends on the environments. If the two materials will be in contact with water or high humidity then you can have some corrosion on the galvanized steel.
It wasn't. Galvanised steel is a manufactured product.
