Pipe Dimensions

The PipeDimensions function provides information on the size of standard pipes including the inner diameter, the outer diameter, the wall thickness and the flow area. This function is applicable for both english and metric size pipes. The data are from:

and

Inputs:
Size is any of the following accepted industry size specification in inches or mm. If units are set to English then use the inch sizes otherwise use the mm sizes.

0.250 8
0.375 10
0.500 15
0.750 20
1.000 25
1.250 32

Schedule$ can be 5s, 5, 10s 10, 20, 30, 40s, 40 60, 80s, 80, 100, 120, 140, 160 or DblEH

Outputs:
OD is the nominal outer diameter in inches or mm (depending if EES is configured in English or SI units)
ID is the inner diameter in inches or mm
WallThickness is the wall thickness in inches or mm
Flow area is the internal flow area in ft^2 or m^2

Example 1: (SI)
$UnitSystem SI
$VarInfo FlowArea units=m^2
$VarInfo ID units=mm
$VarInfo OD units=mm
$VarInfo WallThickness units=mm
Size = 15 [mm]
Schedule$='10'
Call pipedimensions(Size, Schedule$: OD, ID, WallThickness, FlowArea)

{Solution:
FlowArea=0.0002302 [m^2]
ID=17.12 [mm]
OD=21.34 [mm]
Schedule$='10'
Size=15 [mm]
WallThickness=2.108 [mm]}

Example 2: (Eng)
$UnitSystem Eng
$VarInfo FlowArea units=ft^2
$VarInfo ID units=in
$VarInfo OD units=in
$VarInfo WallThickness units=in
Size = 1 [in]
Schedule$='40'
Call pipedimensions(Size, Schedule$: OD, ID, WallThickness, FlowArea)

{Solution:
FlowArea=0.006002 [ft^2]
ID=1.049 [in]
OD=1.315 [in]
WallThickness=0.133 [in]}
