Tube is measured by outside diameter, pipe is measured by inside diameter.
take the outside diameter and subtract the thickness twice.
Pipe bore is the actual minimum inside diameter of a pipe, which is not necessarily the nominal pipe size.
NB = inside diameter of the tube. OD = outside diameter of the tube.
The first difference is actually pipe vs tubing. Pipe is measured at the inside diameter or ID vs tubing being measured at the outside diameter or OD. Dies for bending pipe and tubing are different because of the different measurements. A mandrel is pulled through tubing or pipe to keep the inner diameter constant.
The diameter of a pipe is its width across an open end of the pipe. The inside diameter is the width measuring on the inside of the pipe; the outside diameter is the width measuring on the outside.______________________________________________________________________________________________________For a pipe of circular cross section, its nominal diameter is the diameter of the cross section.The inner diameter is the measuring on the inside of the pipeThe outside diameter is the measuring on the outside of the pipe.
Three-quarter inch diameter pipe refers to the outside diameter. Different pipe types of the same outside diameter usually have different inside diameters. ASTM SCH 40 pipe of 3/4 inch diameter has an inside diameter of 0.824 inches. ASTM CL 200 pipe of 3/4 inch diameter has an inside diameter of 0.930 inches because of the thinner wall.
When dealing with pipe the volume is more important, therefore, I would use the inside diameter.
That would depend on the wall thickness of the pipe. 54 inches is the outside diameter so subtract the pipe wall thickness (x2) adn you have the inside diameter.
Tube is measured by outside diameter, pipe is measured by inside diameter.
take the outside diameter and subtract the thickness twice.
take the outside diameter and subtract the thickness twice.
take the outside diameter and subtract the thickness twice.
The inside diameter (ID) is 8 inches. The nominal pipe size (NPS) and outside diameter (OD) depend on the thickness of the walls of the pipe.
Pipe bore is the actual minimum inside diameter of a pipe, which is not necessarily the nominal pipe size.
2006 civic has 2 1/8 diameter of muffler pipe inside
