A good number to use is 30,000,000 psi (207 GPa)
Black of course
Modulus of elasticity will be 2.06*10^5 N/mm2

Pipe is made of a wide variety of materials - like galvanized steel, black steel, copper, cast iron, concrete, and various plastics such as ABS, PVC, CPVC, polyethylene, polybutylene and more.Pipes are identified by "nominal" or "trade" names that are loosely related to the actual dimensions. For instance, a 2-inch galvanized steel pipe has an inside diameter of about 2 1/8 inches and an outside diameter of about 2 5/8 inches.In plumbing pipe size is referred to as nominal pipe size - NPS, or "Nominal Pipe Size". The metric equivalent is called DN or "diametre nominel". The metric designations conform to International Standards Organization (ISO) usage and apply to all plumbing, natural gas, heating oil, and miscellaneous piping used in buildings. The use of NPS does not conform to American Standard pipe designations where the term NPS means "National Pipe Thread Straight".
it's steel pipe without any processing and packing.
GI Pipe is "Galvanized Iron" Pipe. These days the pipe will likely be made from steel rather than iron.
Galvanized pipe will be silver/gray color. Copper will be copper. Use a magnet, it'll stick to galvanized pipe but not to copper. Drinking water lines should not be black steel pipe.
without touching it? no what you will have to do is sand or scrape the pipe then you will be able to tell the difference. if its a dull metal then its black iron but if it shines then it would be galvanized.

Any plumbing supply and it comes in galvanized steel , black steel, Brass
Ignore the zinc content. Just calculate the volume of steel in the given type (e.g schedule 40), size and length of pipe and multiply by the density of that grade of steel.
Any piping containing Iron, usually Cast Iron, Steel & Galvanized pipe.

if the pipe is structural for erecting a building it will be steel usually galvanized
Either one CAN be used. Galvanized would be preferred in an environment high in chlorine or corrosive materials. Normally though, black pipe, or carbon steel, is used for fire protection because it is much cheaper.
Answer These are different descriptions for a part. Tubular Steel describes the shape. Steel can be ordered in different sizes and shapes and material properties. Tubular Steel is one type of shape and the process for making the tube will cause the properties for that steel to be slightly different. Galvanized Steel describes a type of finish that protects the steel from corrosion. This process alters the surface of the steel that keeps it protected and thus can be used for construction where it is exposed to the elements. I'm sure you can order a steel tube that has a galvanized finish. Many chain-link fences are made from galvanized steel, including the round posts. Custermen
Depends on local codes I use Galvanized piping and fitting when I know the piping is going to be exposed to moisture (dampness) or the elements
