Internal Pressure % SMYS

The calculation provides the maximum internal pressure given pipe specs and % SMYS. These factors are used in the design of roads and railroads. Pressure in the pipe i.e. gauge.
External loading on the pipe is additive and must be considered separately using PLTB API 1102 external loading calculations.
