A nominal 2 valve or pipe refers to the inside or outside diameter?
The nominal pipe size is closest to the inside diameter; however, for exact calculations both should be looked up in a table based on the scheduled pipe size.
How do you calculate the center of a 90 degree pipe elbow?
If your elbow is a short radius it is 1 times your nominal pipe diameter. If it is a long radius it is 1 1/2 times your nominal pipe diameter.show me the exact pattern of long radius
What is 50NB pipe?
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.
What is the formula to ending-to-center dimensions on a long radius butt-weld elbow?
1 1/2 times the nominal pipe size
What does DN mean?
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".

What are those 2 pipe thingys at the ends of bike used for other people to stand on called?
Those "pipe thingys" are referred to as "Pegs".
What is the roundness tolerance for schedule 40 pipe?
The allowable deviation of diameter (schedule 20 and greater) at any point from nominal diameter is: Under 2": +.015/-.031 2"-12": +/-1%
Can a sink drain and a washing machine share a stand pipe drain successfully?
No, stand pipe for washing machine is meant only for washing machine. Tie sink into drain line that washing machine stand pipe is tied into. 2" minimum drain line should be what you tie into. Sink drain line use 1 1/2".
A four inch pipe carry how much more volume than a 2 inch pipe?
It is based on the flow area, which is proportional to the square of the diameter. 2 squared = 4. 4 squared = 16. So, the 4 inch pipe can take 16/4 = 4 times the volume of the 2 inch pipe. It might be less confusing if you had picked sizes other than 2 and 4. This is a rough calculation, since pipe inside diameters are not the same as nominal sizes, but close enough for most purposes.
What is the nominal external and internal diameter?
That is the accepted size of a given pipe. If you use precise enough measurements, it will vary very slightly. If you say a pipe is 1 1/2 inches, everyone knows what you mean and it is close enough for practically any operation.
What is diffirance pipe vs tube?
The purpose with a pipe is the transport of a fluid like water, oil or similar, and the most import property is the capacity or the inside diameter. For a ASME/ANSI B 36.10 Welded and Seamless Wrought Steel Pipe the inside diameter - ID - of a NPS 2 inches pipe with * schedule 40 is 2.067" * schedule 80 is 1.939" The inside diameters are close to 2" and the nominal diameter related to the inside diameter. Outside diameter are 2.375" for both schedules. Since the outside diameter of a single nominal pipe size is kept constant the inside diameter of a pipe will depend on the "schedule" or the thickness of the pipe. The schedule and the actual thickness of a pipe varies with the size of the pipe. It is common to identify pipes in inches by using 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". Nominal Bore (NB) may be specified under British standards classifications along with schedule (wall thickness). The tolerances are looser to pipes compared with tubes and they are often less expensive to produce. The nominal dimensions of tubes are based on the outside diameter. If we look at Copper Tubes - ASTM B88 the outside diameter of a 2" pipe is 2.125", relatively close to 2". The inside diameter of a tube will depend on the thickness of the tube. The thickness is often specified as a gauge. If we look at Copper Tubes - ASTM B88 the wall thickness of 0.083"of a 2" pipe is gauge 14. The tolerances are higher with tubes compared to pipes and tubes are often more expensive to produce than pipes.
