API RP 1102 Pipeline Mass And Weight

Calculate API RP 1102 steel pipeline unit mass (mass per length), unit weight (weight per length), and total mass.

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

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

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

Reference : API RP 1102 : Steel Pipelines Crossing Railroads and Highways (2012)

Calculate API RP 1102 pipeline unit mass and unit weight including contents and buoyancy for multi layer piping.

Calculate unit mass and unit for either dry empty, dry full, wet empty, or wet full pipelines. Select the pipe schedule (NPS or ISO), pipe diameter and wall thickness, or use the user defined option. The line pipe is the first inside layer. The line pipe wall thickness is either taken from the selected schedule value, or the user input wall thickness is used if the user defined wall thickness option is selected. Details for each layer are displayed in the output view at the bottom of the page. Use the Result Table option to display a table of pipe mass and weight for the selected diameter.
