CALCULATOR MODULE : API RP 1102 Pipeline Crossing Line Pipe Schedule ±

Calculate API RP 1102 steel pipeline diameter, nominal wall thickness and pressure containment wall thickness.

For API RP 1102, the fabrication tolerance is included in the design factor. The fabrication tolerance is not required provided that the tolerance is within the relevant specification. The pressure containment wall thickness equals the nominal wall thickness minus the corrosion allowance. The pipe diameter can be defined by either the outside diameter or the inside diameter.

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

CALCULATOR MODULE : API RP 1102 Pipeline Railroad Crossing ±

Calculate API RP 1102 pipeline railroad crossings.

API 1102 is suitable for cased and uncased steel pipeline railway crossings.

The design factors are calculated from the figures. Design factors are extrapolated for input values outside the range in the figures. Extrapolated values should be used carefully (select either constant value or constant slope option). The standard soil weight is 18.9 kN/m^3. Standard loads for single track and double track railroads are included. Soil weight and wheel loads can also be user defined.

Note : The calculations are based on the SI data values. User input values can be either US units or SI units. Change units on the setup page (click the Setup link on the calc bar). Units can be mixed, and do not need to be consistent.

CALCULATOR MODULE : AS 2885.1 Pipeline Road And Rail Crossing ±

Calculate AS 2885.1 pipeline road and rail crossing stress checks.

The methodology is taken from API RP 1102. A design factor of 0.72 should be used for highway and railroad crossings. A factor of 0.9 can be used in other cases. The hoop stress check is not required.
