Weight of one pipe: 0.584 713
Volume of one piece: 442.965
Weight per metre of length: 0.584 713 kg/m
Density used: 1320 kg/m3

Outside diameter = 50
Wall thickness = 3
Length = 1000
Number of pieces = 1
volume_mm3 = pi/4 * (50^2 - (50 - 2*3)^2) * 1000 = 442 965
Volume of one piece = 442 965 / 1000 = 442.965
Density used = 1320 = 1320
Weight of one pipe = 442 965 * 1320 / 1e9 = 0.584 713
Total weight = 0.584 713 * 1 = 0.584 713
Weight per metre of length = 442 965 / 1000 * 1000 * 1320 / 1e9 = 0.584 713

Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula

Volume = (pi / 4) x (OD^2 - ID^2) x length, where ID = OD - 2 x wall
Weight = volume x density, with density = 1320 kg/m3
One cubic millimetre of a material at 1000 kg/m3 weighs exactly one milligram, so the millimetre-to-kilogram step is a shift of the decimal point rather than a rounded factor.

Unfilled polyether ether ketone.

Dimensions are nominal. Mill tolerances on thickness, and the corner radii on formed sections, both move the real weight by a percent or two.

Every field takes inches or feet as readily as millimetres: change the unit next to it and the conversion is done exactly before the arithmetic starts.

Frequently asked

What is the density of PEEK?

1320 kg/m3, which is 1.320 g/cm3. Unfilled polyether ether ketone.

How do you calculate the weight of a PEEK pipe?

Volume = (pi / 4) x (OD^2 - ID^2) x length, where ID = OD - 2 x wall. Multiply the volume by the density of PEEK, 1320 kg/m3, taking care that both are in the same unit system.

Can I enter dimensions in inches?

Yes. Each dimension field has its own unit selector, and inch, foot, millimetre, centimetre and metre entries are all converted exactly before anything is multiplied.

Where the numbers come from

Densities are nominal room-temperature values for the grade named, drawn from the usual mill and handbook figures.
