What is Pipe?

The pipe is pressure tight circular hollow section that used in piping systems to transport gases or fluids.


What is Tube?

Over the internet, you will find that tube is a circular structural member and the confusion start from here. In oil and gas industries, tubes are not just used as a structural part but also used in the heat exchanger and fired heater for a process application. Let’s check the difference. The first difference is how the size is defined for the pipe and tube.


PIPES TUBES
Size Pipe Size Specified in Nominal Pipe Size (NPS) or Nominal Bore (NB) or Diameter Nominal (DN) Tubes sized are specified in millimeter or in inches by outside diameter
Thickness Wall thickness is expressed in schedule number Wall thickness is expressed in millimeter, or inches, or BWG (Birmingham wire gauge.)
Diameter The outside diameter of pipe up to size 12” are numerically larger than corresponding pipe size Outside diameter of tubes is numerically equal to the corresponding size.
Use Used in all process & utility lines Generally used in tracing lines, tubes for heat exchanger & fired heater & in instrument connection.
Also used as a structural member Also used as a structural member Also used as a structural member
Availability Available in the small bore as well as the big bore. Normally small-bore tube is used in process piping.  For structural use, tubs are available in custom sizes.
