API RP 14E Piping Mass And Weight

Calculate API RP 14E platform piping unit mass (mass per length), unit weight (weight per length), and total mass from length.

The mass per joint can be calculated from the joint length. Construction quantities can be calculated from the total pipe length.

Pipe mass and pipe unit weight (weight per length) can be calculated for multi layer pipelines (dry empty, dry full, wet empty and wet full pipelines). For multi layer pipelines, the first internal layer is the line pipe. Change the number of layers on the setup page. The line pipe layer diameter and thickness are calculated from the pipe schedule.

Use the Result Table option to display a table of pipe mass and weight versus wall thickness for the selected diameter.
