Pipe is identified by NB and thickness is defined by Schedule whereas Tube is identified by OD. For more detail about piping click here : http://pipingguide.blogspot.com/

94 mm on a ruler is between 90 mm and 95 mm. On a typical ruler containing both mm and inches scales, where the scales are reversed with respect to each other, 94 mm is opposite 8 5/16 inches.

NB is nominal bore of that pipe, that doesn't mean that the pipe diameter (Inner or Outer)will be equal to the NB, but it is an digit nearest to the out side diameter of the pipe. That digit will be an easily memorable one like 25, 20, 32, 40 etc (Not like 23.25, 27.5, 41.8 etc). In standard pipes, the NB and the outside diameter will be same from 14 inches and above...

it is, probably, a pipe with nominal diameter (DN) 6 mm, and wall thickness 1.727 mm (SCHEDULE 40). See it here: http://en.wikipedia.org/wiki/Nominal_Pipe_Size
A 250 NP pipe is a pipe that is 250 millimeters in diameter and is 10 inches long. It comes in a variety of thicknesses. NB stands for nominal bore. Sometimes this is referred to as NPS which stands for nominal pipe size. NB is a standard for pipe sizes in North America.
Use this formula for weight calculation weight = (OD-Thk)*Thk*.02466 Kg/Mtr Where OD & Thk are in mm

Schedule 80 means "Pipe Wall Thickness as per Sch.80 of ASME B36.10M". Pipe 80 means "3 inch NPS or 80 mm NB pipe as per ASME B36.10M". Hope that it will answer your query adequately. Regards, Bhatta
Nominal bore which is designation for pipe size.
