What is the difference between Pipes and Tube?

People use the words pipe and tube interchangeably, and they think that both are the same. However, there are significant differences between pipe and tube.

The short answer is: A PIPE is a round tubular to distribute fluids and gases, designated by a nominal pipe size (NPS or DN) that represents a rough indication of the pipe conveyance capacity; a TUBE is a round, rectangular, squared or oval hollow section measured by outside diameter (OD) and wall thickness (WT), expressed in inches or millimeters.Pipes and Tubes

? What is Pipe

Pipes are hollow sections with round cross section for the conveyance of products. The products include fluids, gas, pellets, powders and more.

The most important dimensions for a pipe is the outer diameter (OD) together with the wall thickness (WT). OD minus pipes2 times WT (SCHEDULE) determine the inside diameter (ID) of a pipe, which determines the liquid capacity of the pipe

EXAMPLES OF ACTUAL O.D. AND I.D.

ACTUAL OUTSIDE DIAMETERS

  • NPS 1 actual O.D. = 1.5/16″ (33.4 mm)
  • NPS 2 actual O.D. = 2.3/8″ (60.3 mm)
  • NPS 3 actual O.D. = 3½” (88.9 mm)
  • NPS 4 actual O.D. = 4½” (114.3 mm)
  • NPS 12 actual O.D. = 12¾” (323.9 mm)
  • NPS 14 ACTUAL O.D. = 14″ (355.6 MM)

ACTUAL INSIDE DIAMETERS OF A 1 INCH PIPE

  • NPS 1-SCH 40 = O.D.33,4 mm – WT. 3,38 mm – I.D. 26,64 mm
  • NPS 1-SCH 80 = O.D.33,4 mm – WT. 4,55 mm – I.D. 24,30 mm
  • NPS 1-SCH 160 = O.D.33,4 mm – WT. 6,35 mm – I.D. 20,70 mm

Such as above defined, the inside diameter is determined by the oudside diameter (OD) and wall thickness (WT).

The most important mechanical parameters for pipes are the pressure rating, the yield strength, and the ductility.

The standard combinations of pipe Nominal Pipe Size and Wall Thickness (schedule) are covered by the ASME B36.10 and ASME B36.19 specifications (respectively, carbon and alloy pipes, and stainless steel pipes).

?What is Tube

The name TUBE refers to round, square, rectangular and oval hollow sections that are used for pressure equipment, for mechanical applications, and for instrumentation systems.

Tubes are indicated with outer diameter and wall thickness, in inches or in millimeters.
