Pipe Weight Calculator

Pipe weight comes from the ring of metal in the wall, so the outside diameter, the wall thickness and the density are all it takes. Pick a nominal size and a schedule and the standard dimensions are filled in for you, or choose a copper water tube size and type, or enter a diameter and wall you have measured. Materials cover carbon and stainless steel, copper, brass, aluminium, cast iron, PVC and CPVC, and you can override the density with your own. It also gives the weight with water or oil inside, which is what the hangers actually carry once the line is in service.

Calculator Type
That Density Is In
Only used when you put a density in above. A US material sheet gives carbon steel as 0.284 lb per cubic inch or 490 lb per cubic foot; a European one gives 7850 kg/m3 and a metallurgist 7.85 g/cm3. They are the same steel.
Piece Length In
Pipe comes in 21 foot random lengths in the United States. Every row below that quotes a length follows this, and the weights are given in both pounds and kilograms either way.
Nominal size is a name, not a measurement. 2 in pipe is 2.375 in across the outside. DN is the same pipe under the metric name a European or Asian drawing uses: DN 50 is NPS 2, not 50 mm of anything.
In the unit picked just below. Leave it at zero and the density of the material above is used; zero means that in every unit.
Left blank it is one foot, so the weight per unit length above still means something on its own.

Copper tube is named half an inch small: 3/4 in tube is 0.875 in across the outside.
Left blank it is one foot, so the weight per unit length above still means something on its own.
