Round Steel Cap

Nominal Bore (NB) is the inside diameter of the pipe

Outside diameter (OD) is the outside diameter of the pipe.

T - is the wall thickness of the pipe the greater the thickness the outside diameter expands not the inside diameter.

Pipe has always been supplied by this way mainly pipe is used in the Gas and water industry so the inside diameter is important moving water and gas the more pressure of gas and water the thicker the wall thickness needs to be.

Saying that there is round gal pipe being supplied designed for structural use.
