3/4 inch steel pipe if making a strong double layer frame.
It can be colored, polish, etc...The most beautiful are polished.
Yep, you can weld steel to stainless and you can weld stainless to steel. You can use steel or stainless welding rod in either case but the steel or steel welding rod will of course rust.
A Corncob pipe.
It depends on the type of system you have. 1 pipe in, or 1 pipe in and 1 pipe out. Single pipe in/out, try replacing the relief valve or simply shimming the end of the radiator opposite where the pipe comes in. This lets water bleed out of the radiator and stops the klanging.

The answer depends on the thickess of the pipe. The universal formula for carbon steel pipe weight is 10.6802 x T x (OD-T) T=Thickness of pipe OD=Outside Diameter If your pipe was carbon steel with a thickness of .375" it would be 238.8 lbs/ft
Schedule 40 PVC is the type and thickness of water pipe.
assuming it's hollow. 10.68*ID*(OD-ID)
7.227
Not sure what you mean by pressure fittings. Threaded fittings for steel pipe are pressure fittings. Steel pipe with a 3/4" O.D. is known as 1/2" I.P.S. (Iron Pipe Size) pipe.
Kindly adviseSCH20 are suitable for 18" exhaust pipe urgently and are there any spec to justify if suitable on SCH20 instead of SCH40 pipe?

OD is Outside Diameter - at least when you are talking about pipe...
id means inside diameter, od means outside diameter, copper pipe and tubing is measured by the od, therefore the od the pipe or tubing will be the same as the id of the fitting
