ASME B31.4 (2012) Liquid Pipeline Wall Thickness From Hoop Stress

ASME B31.4 (2012) Liquid Pipeline Wall Thickness From Hoop Stress Calculations

Calculate ASME B31.4 liquid pipeline wall thickness.

The wall thickness is calculated using Barlow's equation. The mid wall diameter option (Dm) should only be used for offshore pipelines. The girth weld factor does not apply to offshore pipelines.

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 can be calculated from either the outside diameter (constant OD), or the inside diameter (constant ID). The corrosion allowance is assumed to be on the inside of the pipeline.

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 (water depth is relevant for subsea pipelines only). The calculators do not check transient pressure.
