Compressor Station Piping - Pipe Diameter, Wall Thickness and Gas Velocity

This application uses gas velocity and flow rates to determine the minimum required pipe diameter for station piping.

𝑣  − Gas Velocity[ft/min]

𝑄  − Flow Rate[MMCFD]

𝑊_𝑡  − Wall Thickness[in]

𝑃 − Design Pressure[psi]

𝐹 − Design Factor

𝐸 − Longitudinal Joint Factor

𝑇 −Temperature Derating Factor

𝑃_𝑏 − Base Pressure[psia]

𝑇_𝑓 − Flowing Temperature[°R]

𝑍 − Compressibility Factor

𝐷 − Internal Pipe Diameter[in]

𝑃_𝑓− Flowing Pressure[psia]

𝑇_𝑏 − Base Temperature[°R]

Note: Gas velocity in piping should not exceed 2000(ft/min)
