ASME B31.4 Pipe Wall Thickness Modules

Calculate ASME B31.4 oil and liquid pipeline wall thickness from hoop stress for onshore and offshore pipelines.

Select the appropriate line pipe schedule (ASME or ISO etc) and stress table (API, ASM, DNV etc), and material. Wall thickness is calculated using Barlow's formula. For offshore pipelines either the pipe outside diameter or the mid wall diameter can be used to calculate wall thickness. The wall thickness should be checked for all elevations. Use the Result Plot option to plot required wall thickness versus elevation, or hoop stress versus elevation for user defined wall thickness.
