The thickness of 40mm NB MS Pipe is 4mm Regards, ZAFFAR EKBAL +91-9001798487
Yes, a diameter can be regarded as a special case of a chord. NB: NOT ALL CHORDS ARE DIAMETERS!
To find the diameter of a circle divide its circumference by pi
The Radius. NB The distance from any point on a circle , through the centre, to the opposite point on the circle ( a straight line) is the diameter.
YES!!! 46.23 = 46.230 NB The right hand 'zero' is trivial, unless there are further numbers to the right again. Similarly 046.230 - 046.23 = 46.23 NB The 'zeroes' to the left of the integers and to the right of the decimal digits are trivial and can be ignored. However, the 'zeroes' in such numbers as '406.23 or 406.203 or 46.203 etc., CANNOT be ignored.
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...
the inner diameter of the pipe Nominal bore (NB) is 40 mm
NB = inside diameter of the tube. OD = outside diameter of the tube.
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.
NB = Nominal Bore. Bore is the internal diameter of the pipe. The 50 is referring to 50mm (5cm). So it boils down to a pipe with an internal diameter of 50mm.
NB (nominal bore) is the European designation equivalent to NPS is DN (diamètre nominal/nominal diameter/Durchmesser nach Norm), in which sizes are measured in millimeters. NB (nominal bore) is also frequently used interchangeably with NPS.You can refer more details herehttp://www.piping-engineering.com/nominal-pipe-size-nps-nominal-bore-nb-outside-diameter-od.html
NB = Nominal Bore
The conversion factor to convert inches to "Nominal Bore" (NB) is 25.4 mm per inch. NB sizes are based on the internal diameter of a pipe, and they do not directly correlate to inches.
