Pump Station Piping - Pipe Wall Thickness

Pipe wall thickness (WT) is based pipe diameter, SMYS, internal design pressure/factor, joint factor and sum of allowance WT.

𝑡_𝑛 − Nominal Wall Thickness />Satisfying Requirements for Pressure and Allowances [in]
𝑡 − Pressure Design Wall Thickness [in]
𝐴 − Sum of Allowances for Threading and Grooving
𝑃_𝑖 − Internal Design Gauge Pressure [psig]
𝐷 − Outside Pipe Diameter [in]
𝑆 − Applicable Allowable Stress Value [psi]
