ASME B31.4 (2009) Liquid Pipeline Wall Thickness

ASME B31.4 (2009) Liquid Pipeline Wall Thickness Calculations

Calculate ASME B31.4 liquid pipeline wall thickness.

The wall thickness is calculated using Barlow's equation. The corrosion allowance should include mechanical allowance (eg threads), erosion allowance and any other allowances. The design factor F includes an allowance for negative maufacturing tolerance or underthickness for approved pipeline specifications (403.2.1). The wall thickness for each pipeline section should be determined for the maximum static pressure or static pressure difference, allowing for local elevation and water depth.
