5) Pipes & Tubes

To determine weight in kgs of raw material used in 100 meter length
(dimension in mms.)
a) LD Pipes & Tubes = (OD+ID) x (OD-ID) x 0.0723
b) HD Pipes & Tubes = (OD+ID) x (OD-ID) x 0.075
c) Rigid PVC pipes = (OD+ID) x (OD-ID) x 0.11
d) Plasticised clear PVC = (OD+ID) x (OD-ID) x 0.1
e) Opaque PVC pipe = (OD+ID) x (OD-ID) x 0.10214
f) Cable coating = (OD+ID) x (OD-ID) x 0.114
g) Nylon = (OD+ID) x (OD-ID) x 0.8957
Example - HD pipe ID = 15 mm, OD = 18 mm
(18+15) (18-15) (0.075) = 33 x 3 x 0.075 = Wt. of 100 meter pipe of above size
Solid round extruded rods can be calculated as:
1 L. D. POLYTHENE D x D x 0.0723
2 H.D. POLYTHENE D x D x 0.075
3 RIGID P V C D x D x 0.11
4 Plasticized clear P V C D x D x 0.1
5 Opaque PVC Pipe D x D x 0.1021
7 Nylon D x D x 0.8957
