Pipes & tubes have the same purpose for fluid transfer, however Pip is measured in terms of its Internal diameter (I.D) whereas tubes are measured in terms of its Outside Diameter O.D
e.g An 1 1/4 " Pipe will have 1.25" ID + Pipe thickness
A 1 1/4" Tube will be its actual OD i.e 1.25
Tube is measured by outside diameter, pipe is measured by inside diameter.
Pressure rises in the tube.
NB = inside diameter of the tube. OD = outside diameter of the tube.
Pipe n tube are same in shape etc. BUT only difference is Pipe is used for Transferring Material (Gas, Liquid etc.) AND where it is used for Heat Exchanging purpose , It is called TUBE.
Pipe organ has the most harmonics.
The main difference between tube and pipe arises while considering the standard dimensions. The nominal sizes for pipes and tubes are determined differently. For pipes, the ID or Internal Dimension is the pipe size and for tubes the OD or Outer Dimension is considered the tube size.
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.
Pipe n tube are same in shape etc. BUT only difference is Pipe is used for Transferring Material (Gas, Liquid etc.) AND where it is used for Heat Exchanging purpose , It is called TUBE.
A hose is usually made of plastic or rubber. A pipe, on a motor vehicle is made of metal,steel, copper , galvanised. A tube is also made of metal ,but has a much thinner wall . (ie the difference between the outer diameter and the inner diameter)
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/
Weldolet has a Bevelled end to butt weld the pipe whereas in sockolet the pipe/tube goes inside it and there it is fillet welded.
Tube is a made up of rubber, while pipe is a round solid material.
