Hydrostatic Test Water Volume Calculator

How much water to fill the line for a hydrostatic test. Enter pipe OD, wall and length; get gallons and barrels.

Hydrostatic Test Water Volume

Pipe OD (in)

Wall thickness (in)

Line length (ft)

Volume to fill a full line: V = (pi/4) x ID^2 x L. Add makeup water for pressurization (pipe expansion plus water compressibility) on top of this fill volume. 1 bbl = 42 US gal. Confirm against your test procedure.
