What is the difference between "Pipe" and "Tube" ?
Pipe is measure by inside diameter and tube by outside diameter.
Pipe is for larger sizes and tube for smaller sizes
Pipe is measured by inside diameter and tube is measured by outside diameter
Pipe is used for conveying fluid for mass transfer applications, whereas tube is used for conveying fluid with heat transfer applications.
Pipe is identified by NB and thickness by Schedule whenever Tube identified byOD and thickness
In pipe the inside diametr is constant and outside dia varies with the higher schedule where it is viceversa in the case of tue
A pipe is used convey the fluids from one location to another location. Pipes are always in round shape. But in tubes it is in square or rectangular shapes.
BOTH USED FOR FLUID TRANSMISSION.PIPE IS MEASURED IN NB NOMINAL BORE(INSIDE DIA)WHERE AS TUBE IS MEASURED IN OD(OUTSIDE DIA)
Pipe is normally identified by NPS and generally used to transport gases or fluids. While Tube is identified by OD and Thickness and generally used for structural purposes
Pipe is used for conveying fluid for mass transfer applications, whereas tube is used for conveying fluid with heat transfer applications.
A pipe is a tube with a round cross section conforming to the dimensional requirements for nominal pipe size as tabulated in ANSI B36.10. A tube is a hollow product of round or any other cross section having a continuous periphery. Tubes can be used in structural applications.
Pipe is made seamless or rolled and welded (sometimes referred to as ERW pipe) . The pipe sizes up to 12' has a nominal size which is close but not the same as the actual O. D. Pipe in sizes 14" and larger have an O. D. the same as the nominal size
Tubing is normally "cold drawn" seamless with the O.D. the same as the size designation (i.e.: 1" inch tubing has an O. D. of 1 inch) . You can get different pressure ratings of 1" tubing by changing the wall thickness. Thus the I. D. is smaller
In Pipe OD is fixed and ID varies with Schedule whereas in Tubes ID is fixed and OD varies with Thickness (Tubes are specified based on the ID)
Tube application in: boilers, heat exchangers, radiators, etc.
Pipe is identified by NB and thickness by Schedule whenever Tube identified byOD and thickness is BWG.
Difference between pipe & Tube is measured of DIA. PIPE measured from INSIDE DIA & TUBE measurement from OUTSIDE DIA.
Pipe is for larger sizes (used in industral application) and tube for smaller sizes (used in domestic application)
