Pipe Weight Formula - This formula can be used to determine the weight per foot for any size of pipe with any wall thickness.
The formula is: Wt/Ft = 10.69*(OD - Wall Thickness)*Wall Thickness
Weight of empty pipe per unit length can be calculated as
wp = ρm Am
= ρm π (do2 - di2) / 4
= (π / 4) ρm (do2 - di2)
where
wp = weight of empty pipe per unit length (kg/m, lb/in)
ρm = density of pipe material (kg/m3, lb/in3)
Am = cross-sectional wall area of pipe (m2, in2)
do = outside diameter (m, in)
di = do - 2 t = inside diameter (m, in)
t = wall thickness (m, in)
Weight of pipe with liquid can be calculated as
w = wp + wi
= ρm Am + ρl Ai
= (ρm π (do2 - di2) / 4) + (ρl π di2 / 4)
= (π / 4) [ρm (do2 - di2) + ρl di2]
Weight of liquid in pipes per unit length can be calculated as
wl = ρl Ai
= ρl π (di / 2)2
= (π / 4) ρl di2
where
wl = weight of liquid in pipe per unit length of pipe (kg, lb)
Ai = cross-sectional inside area of pipe (m2, in2)
ρl = density of liquid (kg/m3, lb/in3)
